Thermostat products, also known as temperature controllers, are instruments made using electronic technology, automation technology, and control technology to control and regulate temperature. They are widely used in a variety of scenarios in homes, offices, factories, etc., such as in thermostatic laboratories, greenhouses, drinking fountains, air conditioners, thermostatic boxes, and other machines and equipment. The following is a detailed introduction to the thermostat products:

1.Working Principle
The working principle of the thermostat is mainly realized through the following steps:

Temperature sensor sampling and monitoring: temperature sensor is the key component of the thermostat, responsible for detecting the ambient temperature and converting the detected temperature value into an electrical signal, which is then passed to the control circuit for processing. Temperature sensors are generally used thermistors, thermocouples or infrared sensors.
Processing and judgment of the control circuit: the control circuit is the core part of the thermostat, which processes and judges the electrical signals transmitted by the temperature sensor, and starts or stops the heating or cooling equipment by controlling the actuator according to the difference between the set temperature value and the actual detected temperature value.
Actuator action: the actuator is the output part of the thermostat, according to the instructions of the control circuit to start or stop the heating or cooling equipment. The actuator usually uses electronic components such as relays, solenoid valves or transistors.
Display and Setting: The thermostat is usually also equipped with a display for showing the current ambient temperature and the set temperature value, which is convenient for users to set and adjust.

2.Product Classification
Thermostat products can be divided into various types according to different working principles and application scenarios, mainly including:

Sudden jump thermostat: model collectively referred to as KSD, mainly as a variety of electric heating products with overheating protection when the first level of protection, effectively preventing electrical burnout and safety accidents.
Liquid up type thermostat: using the principle of liquid thermal expansion and contraction, through the expansion or contraction of the membrane box to drive the switch on and off, stable and reliable, control temperature control adjustment range.
Pressure-type thermostat: through the closed temperature-sensitive material filled with the temperature package and capillary tube, the change of the controlled temperature into the space pressure or volume changes, to reach the temperature setting value automatically close the contact.
Electronic thermostat: using resistance temperature sensing method to measure the temperature, generally use thermistors as temperature measurement resistance, with high precision and fast response characteristics.

3.Purchase suggestions
When purchasing thermostat products, you can consider the following aspects:

Application scenarios: choose the right type of thermostat according to the specific application scenarios, such as home use can choose electronic thermostats, while industrial settings may require more durable liquid up or pressure thermostats.
Precision and stability: choose the right precision and stability according to the needs, high precision thermostat can provide more accurate temperature control.
Brand and quality: Choosing a well-known brand and high-quality products can ensure product reliability and after-sales service.
Functionality and ease of use: Consider the functionality and ease of use of the thermostat, such as whether it has a display and setting functions, whether it is easy to install and debugging.
