Model designation method

The model differs in the case of temperature power sensors and electronic thermostats.

The model designation method, for example, in the case of a temperature power sensor (TPS) [MQT8K K35XC1.5(DS)], includes the model name, a space, K for crossbar contacts, operating temperature, contact configuration (X,X,Y,Y), DIFF. rank display, tolerance display (for custom orders only), and double shield (indicating compliance with overseas standards). This varies significantly in the case of electronic thermostats (temperature variable type), electronic thermostats (temperature fixed type), high-temperature thermostats, and disc-type thermostats (for protectors). For more details, please download the catalog.

Issues when using a thermostat in a DC voltage circuit.

When using in a DC voltage circuit, care must be taken regarding contact wear.

When using a thermostat in a DC voltage circuit, it is important to pay attention to contact wear. Essentially, you should check the contact capacity according to the voltage/DIF. rank. In other words, for example, AC125V and DC12V can both handle up to 5A, while AC250V and DC24V can handle up to 3A at the same current. The mechanism by which contacts wear due to 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. For more details, please download the catalog.

Display method of connection configuration

Due to manufacturing reasons, the display method of the thermostat as a controller is complex.

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 rising temperature are designated as X, and those that close with rising 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, we use the symbols X-bar (a line over X) and Y-bar (a line over Y). 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.

Knowledge for creating a good temperature control system.

The thermal control system consists of four elements: the user, the heated object, and others.

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 sufficiently, 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 wait a little longer for the initial temperature rise, the lifespan may increase threefold. 2. Let's first reconfirm the ultimate goal of this temperature control and consider the surrounding materials. We should reconsider such matters. For more details, please download the catalog.

Glossary of Thermostat Terms

This is an introduction to terms such as differential (response) tolerance (tolerance).

This is an introduction to the glossary of thermostat terminology. ● Differential (DIFF.) refers to the temperature difference in the ON/OFF state (also known as hysteresis). Control-type thermostats can maintain high precision in temperature control due to their small ON/OFF differential, but if the differential 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 differential in the design. ● Tolerance refers to the allowable precision values for settings such as the target temperature. It is expressed as OFF setting value: 30℃±3 (℃) and DIFF.: 3–6 (℃). For more details, please download the catalog.
