This is an introduction to thermistors and the characteristics of thermistor control (advantages and disadvantages). ● Advantages: They are used as sensors for temperature measurement. The temperature range is approximately from -50°C to 350°C. If the resistance value is known for a certain temperature, the temperature can be determined from the resistance value. An advantage is that when used in large quantities, they can be produced cheaply with a circuit board, electronic circuits, and power supply. ● Disadvantages: When used in small quantities, the cost increases, and the appeal of thermistors diminishes. Additionally, electrical components may not function properly due to cold, heat, or noise, making it necessary to be very careful about the installation environment.

This is an introduction to a glossary of thermostat terms. ● Differential (DIFF.) refers to the temperature difference in ON/OFF states (also known as hysteresis). Control-type thermostats can maintain high precision in temperature control due to their small ON/OFF differential, but if the DIFF. is too small, it can lead to an increased number of operations, resulting in a shorter lifespan. Therefore, it is important to select the optimal DIFF. in the design phase. ● Tolerance refers to the acceptable precision range for set temperatures, etc. It is expressed as OFF setting value: 30℃±3 (℃) and DIFF.: 3–6 (℃).

We will introduce knowledge for creating a good temperature control system. A thermal control system consists of four elements: [User], [Power source such as heater or cooler], [Thermostat], and [Object to be heated]. Let's thoroughly investigate whether these four elements are being used in the best possible way. If we refine this enough, there should be no defects. 1. For example, are you using an oversized heater to quickly raise the temperature of the object to the desired level relative to its heat capacity? If you can afford to wait a little for the initial temperature rise, the lifespan may increase by three times. 2. Let's first reconfirm the ultimate goal of this temperature control and consider surrounding materials. Let's reconsider such matters. For more details, please download the catalog.

I will explain the regional share of Temperature Power Sensors (TPS). It has been over 20 years since Temperature Power Sensors were introduced to the market. During this time, they have gradually penetrated the world with catchphrases such as "high-performance thermos that can replace electronic thermos at a fraction of the price." It is natural for advanced products like TPS to be adopted first in regions with significant technological accumulation. In developing regions, the manufacturing stage involves receiving blueprints from advanced regions, so it will take time before they reach the level of creating unique products using TPS.

As for the applications of the Temperature Power Sensor (TPS), even if electrical products of a nature that have never existed before are created, it doesn't necessarily mean they will become hits just because they are "cheap, high-performance, compact, and long-lasting." It has been a challenge to achieve this. Over the past 15 years, we have accumulated points such as: "This product excels in this aspect compared to similar products currently on the market," "This is more expensive compared to this, but it excels in this area," and "Household appliances were satisfactory with conventional products since they are used in large boxes, but for communication devices, conventional products do not fit, making the Temperature Power Sensor just right." I feel that finally, in the 21st century, it has been recognized and evaluated in the market. For more details, please download the catalog.

As a method of displaying the contact configuration, our company manufactures thermostats used as controllers, which makes the display method more complex than in the case of protectors. In written form, it can be expressed as follows: ● Items that open with an increase in temperature are designated as X, and those that close with an increase in temperature are designated as Y, indicating the operating temperature during temperature rise (high temperature side). For the same items, if the operating temperature during temperature drop (low temperature side) is emphasized, the symbols X-bar (a line over X) and Y-bar (a line over Y) are used. X-bar represents items that close with a decrease in temperature, while Y-bar represents items that open with a decrease in temperature. For more details, please download the catalog.

I will explain about crossbar contacts (micro-capacity contacts). Our 2Amp and 5Amp series set the minimum current for standard contacts at 50mA, and below that, we use crossbar contacts, referred to as K contacts. The range for crossbar contacts is defined as 1mA to 100mA, so the shared range between standard contacts and micro-capacity contacts is between 50mA and 100mA. Please consider the range of crossbar contacts to be from 1mA to 100mA. Due to the small contact area, the likelihood of minor debris getting trapped within the contacts and causing contact failure is low. For more details, please download the catalog.

As a practical method for measuring specific heat capacity, the thermal time constant is an accurate way to grasp the heat capacity of an object, but it is somewhat too academic for everyday practical use. Therefore, as a practical guideline, I have summarized in a table how well the thermostat's temperature can adapt to changes in ambient temperature compared to the thermostat's simple heat capacity. If the rate of change in ambient temperature is fast, the thermostat's thermal adaptation will be delayed, but if the change in ambient temperature is slow, it can be seen that the thermostat can sufficiently keep up with the temperature changes.

In the thermal time constant of temperature power sensors, those with good thermal conductivity become familiar more easily, while those with poor thermal conductivity take longer to become familiar. The degree of familiarity is represented by the thermal time constant. We measured the thermal time constants of the MQT8 series of temperature power sensors. The thermal time constant is expressed as the time it takes to reach 60% of the temperature change range; as shown in the difference table, regardless of whether the temperature change range is large or small, if the object and measurement conditions are the same, the same value is indicated. The thermal time constants measured in air with a wind speed of 1 to 1.5 m are 102 seconds for MQT8, 160 seconds for M2, and 195 seconds for M3. In water, heat is more easily drawn away from the object than in air, so the thermal time constant measured in water is smaller. For more details, please download the catalog.

When using a thermostat in a DC voltage circuit, one issue to be aware of is the wear on the contacts. Essentially, you should check the contact capacity according to the voltage/DIFF. rank. In other words, AC125V and DC12V can each handle, for example, 5A, while AC250V and DC24V can each handle, for example, 3A, up to the same current. The mechanism by which contacts are damaged by arcing consists of four elements: (a) the magnitude of the voltage, (b) the magnitude of the current, (c) the rate of contact separation and engagement, and (d) the material of the contacts and the condition of the contact surface.

This is an explanation about internal heat generation based on load. In electrical components such as relays, thermostats, and switches that open and close contacts, the load capacity is constrained by the heat generated at the contact points. Particularly, since thermostats are switches that operate based on temperature, the heat generated at the contact points affects the operating temperature and the differential. The contact capacity display of temperature power sensors is indicated with a margin for heat generation. For more details, please download the catalog.
