WIKA offers a variety of temperature calibration services. It is important to adhere to traceability in accordance with international standards when conducting calibrations. For high-precision calibration standards used in factories and laboratories, it is necessary to use even more precise references. One method is fixed-point calibration based on the International Temperature Scale ITS-90. This calibration utilizes specific points such as the melting points and triple points of substances. These specific points are extremely reproducible and stable, allowing for high accuracy to be achieved. At WIKA's German facility, it is possible to set the triple point of silver, the triple point of water, the melting point of gallium, the melting point of tin, the melting point of zinc, and the melting point of aluminum, enabling calibration between -38.8344 °C and 660.323 °C.

WIKA defines a "total error range" for all pressure sensors. The operating temperature of a pressure sensor consists of ambient temperature and medium temperature. It is more common to deviate from the ambient temperature that guarantees the accuracy of the pressure sensor. These temperature influences affect the sensor's accuracy. The total error range of WIKA pressure sensors indicates the maximum deviation. While deviations vary by instrument, they always fall within the total error range. The total error range is based on the reference temperature and displays deviations that can correspond to typical usage temperatures. The total error range of pressure sensors is listed in WIKA data sheets, reflecting the minimum accuracy here.

▬ Content of this video ▬▬▬▬▬▬▬▬▬▬▬▬ 00:00 Introduction 00:04 How does a thermocouple work? 00:55 Cold junction compensation 01:25 Voltage curve of thermocouples and pairing of materials 01:58 Types of thermocouples In general, in the industrial sector, either resistance temperature detectors or thermocouples are used for temperature measurement. The measurement principle of resistance temperature detectors is explained in the video below. Thermocouples use two different metals that are connected at the measurement point. Thermocouples with a solid weld of the two dissimilar metals have high vibration resistance, making them commonly used in the industry. When the temperature at the thermocouple measurement point rises or falls, the electron density of the two metals changes. This change in electron density generates a voltage at the output connection point. Thermocouples operate according to the principle of comparative measurement. In other words, the temperature at the measurement point is expressed as a thermoelectric voltage relative to the temperature at the output connection point. Since temperature measurement at the measurement point cannot be done with just the temperature difference, cold junction compensation is necessary. This ensures that the measurement results are not affected by the ambient temperature of the connection terminals.

(The mechanism of thermocouples is explained in this video: In temperature resistance sensors, temperature is measured using a resistance thermometer that measures ohmic values. The "Pt" in Pt100 represents the chemical element platinum, and the 100 indicates the resistance value of the sensor at 0 degrees Celsius. Therefore, the most commonly used measuring resistor, Pt100, means that its electrical resistance is 100Ω (ohms) at 0°C. For special applications, Pt1000 temperature sensors are also used. The change in electrical resistance due to temperature rise and fall conforms to the characteristic curve defined by international standards. Temperature can be measured with very high accuracy based on the measured resistance value.

Your measuring instrument can be checked for accuracy and calibrated at the WIKA calibration lab. Calibration can be performed either as a general calibration or as an ISO 17025 accredited calibration. The results of both types of calibration will be documented in a calibration certificate, and a calibration sticker will be affixed to the calibrated instrument. Only ISO 17025 accredited calibrations guarantee that testing is conducted using testing equipment certified by an international accreditation body. The traceability diagram is structured to show the hierarchy from the standard instruments used in the inspection factory to the test standards and national standards. Measurement uncertainty is documented by clarifying not only the factors of measurement error such as hysteresis and variation but also measurement deviation and the uncertainty of the reference instruments. Compared to general calibration, ISO 17025 accredited calibration is more accurate, broadly applicable, and internationally recognized. For general calibration, the instrument difference is determined by considering only hysteresis. The calibration performed at the time of factory shipment is issued as an inspection certificate in accordance with DIN / EN 10204.

A pressure gauge is a pressure measuring device equipped with a flexible measuring element, and millions have been used in various industrial applications. Depending on the application of the pressure gauge, pressure elements such as Bourdon tubes or diaphragm elements are used. In the case of Bourdon tube pressure gauges, pressure is measured through a Bourdon tube, which is a C-shaped curved tube with a non-circular cross-section located inside the gauge. The Bourdon tube exhibits a movement known as "tube internal movement." Bourdon tube pressure gauges are highly versatile and can be used for most applications. Bourdon tubes have the following advantages compared to diaphragm elements: - They can accommodate pressure ranges from 0 to 0.6 bar for low pressure to 0 to 10,000 bar for high pressure. - They can achieve accuracy up to class 0.1, which is the calibration standard. - They are easy to manufacture. - Connections and sealing with pressurized components are straightforward. Depending on the material and pressure load, they can be attached using soldering, welding, or screwing methods.

Many WIKA pressure gauges have a vent valve shaped like a yellow lever on the top of the case. The valve is closed upon delivery of the product, but in order for the pressure gauge to function correctly, the valve should be opened during the commissioning process. The internal pressure of a highly airtight pressure gauge can change due to temperature variations, such as direct sunlight. Changes in pressure within the case can lead to unacceptable deviations in the accuracy of the pressure gauge. Pressure compensation between the inside of the pressure gauge case and atmospheric pressure is performed by the vent valve. However, not all WIKA pressure gauges are equipped with a vent valve. If a higher protection rating is required, pressure compensation is performed through a diaphragm mounted on the back of the case. In pressure ranges above 16 bar, the measurement errors caused by pressure increases within the pressure gauge case can be ignored, and the pressure gauge operates within the specified accuracy. Why is the yellow lever closed? Pressure gauges are typically transported in a horizontal position. If the vent valve of a filled pressure gauge is left open, the filling liquid may leak out of the instrument. Please keep it closed during transport to prevent oil leakage.

Basically, diaphragm seals are used in pressure measurement applications where direct contact between the measuring instrument and the medium must be avoided. Furthermore, diaphragm seals are also used when the measuring location is difficult to access for instrument installation or reading. In both cases, the pressure is transmitted to the measuring instrument through the system filling liquid within the case of the diaphragm seal. The diaphragm seal components can be made from various materials such as stainless steel, Hastelloy, Monel, and tantalum. Additionally, coatings with ECTFE, PFA, and gold are also possible. Diaphragm seals coated with the patented Wikaramic are highly wear-resistant and can be used with abrasive media.

The dials of mechanical pressure gauges and thermometers contain various pieces of information. This is defined by standards such as EN 837 and EN 13190, and care must be taken when reading them. What information is provided? What is the difference between pressure gauges and thermometers? And what should be noted when reading them? In mechanical pressure gauges and bimetallic or gas thermometers, the measured values are indicated by a pointer. The dial contains the following information: Units: For pressure measurement, units such as bar, psi, and kPa are used, while for temperature measurement, Celsius and Fahrenheit are used. Accuracy class: For pressure gauges, this indicates how much the measured value can deviate from the scale in percentage. Typical accuracy classes for pressure gauges are 0.6, 1.0, 1.6, and 2.5. For mechanical thermometers, the accuracy classes are 1 and 2. The accuracy class indicates the maximum error based on the scale range (in accordance with EN 13190). The scale is very important for correctly reading the measuring instrument. The scale of the pressure gauge is displayed accurately within a range of 270 degrees (angle). In the case of mechanical thermometers, this scale can deviate by up to 20 degrees (angle).

What does the accuracy of a pressure sensor mean, and how does the inaccuracy that leads to errors in the desired measurement results arise? This video explains the most important factors related to the accuracy of pressure sensors: zero point error, span error, and non-linearity. Non-linearity refers to the maximum error in the characteristic curve of the ideal straight line. There are various methods to determine the ideal straight line. The two most common are the terminal method and the best fit straight line (often referred to as BFSL in data sheets). When comparing the two methods, the terminal method typically yields deviations that are twice those of the best fit straight line. Therefore, even when comparing the non-linearity of electronic pressure gauges from different manufacturers, compatibility exists only when non-linearity is measured using the same method. The interaction of zero point error, span error, non-linearity, and other errors such as hysteresis and reproducibility is referred to as "accuracy." The term "accuracy" exists only in the user's documentation and is not clearly defined in any standard.

• Measurement and Analysis Equipment

The measuring medium is pressurized through the pressure receiving part (often referred to as the process connection) to the pressure sensor section. The connection methods for the pressure receiving part include internal diaphragm and flush diaphragm. The choice of which connection method to use depends on the measuring medium. The connection method using an internal diaphragm is easier to handle and can be manufactured at a lower cost compared to the flush diaphragm connection method. It is mainly used for gaseous or liquid pressure media. For all pressure media that may block or damage ports, such as crystalline, viscous, corrosive, adhesive, or abrasive media, the use of a flush diaphragm is recommended. Additionally, in applications where it is necessary to eliminate residues in the pressure connection, a flush diaphragm should be used instead of an internal diaphragm. In the connection method with an internal diaphragm, the measuring medium reaches the sensor diaphragm inside the connection through the pressure port. In the pressure connection with a flush diaphragm, the pressure port itself is flush-sealed using an additional stainless steel diaphragm, allowing the transmitting fluid inside the sensor to transmit pressure to the internal sensor diaphragm.

• Measurement and Analysis Equipment

A bimetallic thermometer operates through a measurement system shaped like a spiral or helical tube. The measurement system consists of two metals with different coefficients of expansion that are joined together to prevent separation. The mechanical deformation caused by temperature changes in the bimetal strip generates rotational motion in the spiral tube. This motion is transmitted to the thermometer's pointer via the pointer shaft. A gas-filled thermometer consists of a stem, capillary, and Bourdon tube within the case. It is configured by combining these components. The measurement system is filled with inert gas under pressure. Temperature changes cause variations in the internal pressure of the stem. The change in internal pressure causes the measurement tube to bend, which is transmitted to the pointer through the movement.

Compared to pressure gauges without liquid filling, liquid-filled pressure gauges have the following advantages: The filling liquid buffers vibrations, protecting the moving parts of the gauge and significantly extending its lifespan. When a pressure gauge experiences strong vibrations, a gauge without filling liquid will have the pointer vibrating greatly, making it difficult to read the values. The filling liquid stabilizes the pointer, making the values easier to read. In cases of low or high ambient temperatures, using filling liquid prevents condensation on the glass surface, greatly improving the readability of the pressure gauge.

Rapid temperature changes do not affect the accuracy of the measurement data. The metal shield inside the device ensures that electric field strengths up to 100 V/m do not affect measurement accuracy. There are also no concerns about functional failures or signal interference due to electronic component interference.

Are you aware of the troublesome situation where, when measuring process temperature and process pressure, it is necessary to read the measurement values on-site and transmit them as electrical signals, requiring two measurement methods? intelliTHERM (temperature gauge with output signal) and intelliGAUGE (pressure gauge with output signal) provide an optimal solution as a replacement for standard temperature and pressure measuring instruments. They offer a 2-in-1 solution, enabling not only visual observation from the display but also the transmission of electrical output signals. A special design with a magnet attached to the pointer transmits changes in the magnetic field, which are measured by a Hall sensor and converted into electronic signals. The movement of the pointer alone generates electronic signals non-contact. The biggest advantage is that there is no need to install two measuring instruments; only one needs to be installed, allowing for cost reduction.

The MTF-1 is available in two sizes, 19 mm and 27 mm, thanks to its simple and flexible options. The 19 mm type, in particular, is designed to be very compact, making it suitable for use in tight spaces. The digital I2C signal used by the MTF-1 transmits data very efficiently with low power consumption, making it ideal for battery-powered solutions. Additionally, the long cycle between battery replacements helps reduce maintenance costs. The I2C protocol transmits temperature signals simultaneously with pressure signals, allowing for equipment condition monitoring. If unexpected temperature changes occur, there may be an issue with the application. This enables the coexistence of condition monitoring and preventive maintenance, significantly extending the system's lifespan and making it easier to plan repairs. The MTF-1 features a dry stainless steel measuring cell that is welded to the process connection, and since the measuring cell is not oil-filled, the risk of media contamination is minimized. The MTF-1 pressure sensor module is provided to customers with a corrected output signal. It does not require field calibration, leading to savings in maintenance time and costs.
