[Video Introduction] How to Read Pressure Gauges and Thermometers Correctly | What to Pay Attention To?
What information is displayed on the dials of mechanical pressure gauges and thermometers? What is the difference between a pressure gauge and a thermometer? What should you be careful about when reading the values?
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).

basic information
The distinction between the scale range and the measurement range is only found in thermometers. The measurement range guaranteed by the accuracy grade is distinguished by a black triangle symbol. Pressure gauges also have a triangle, but this indicates the maximum pressure due to static load, meaning the pressure gauge can withstand without damage regardless of how much pressure load it is permanently exposed to. The interaction of errors such as zero point error, span error, non-linearity, hysteresis, and reproducibility is referred to as "accuracy." The term "accuracy" only exists in the user's documentation and is not clearly defined in any standard. The dial face also contains other important information printed on it. For example: - Instrument manufacturing standard - Wetted material - Instrument serial number Some pressure gauges have a symbol with an "S" inside a circle. This symbol indicates that it is a safety pressure gauge "S3" that complies with EN837-1 and is equipped with a solid baffle wall, blow-out disk, and laminated safety glass.
