Temperature control components are products and related components that control temperature, such as temperature controllers, temperature sensors, heaters, etc. A temperature controller is a device that has the function of receiving the input of a temperature sensor, etc. and controlling the output of a heater, etc. via a relay or SSR. The control method can be selected from ON / OFF control and PID control according to the application. A temperature controller that integrates a temperature controller and SSR is also available, making it easier to use. Temperature sensors include K-type, J-type, T-type, etc. thermocouples, thermistors, RTDs, etc. Select from characteristics including heat resistance, waterproof, corrosion resistance, etc., and correspond to various tip shapes. Heaters can be selected from cartridge heaters, such as tubular heater and rubber heaters for air / liquid heating, according to the shape and material of the object to be heated, from contact or non-contact operating environment, etc.
