Temperature controllers are widely used in various home appliances, such as water dispensers and heaters. The refrigerator uses a temperature controller to adjust the temperature to keep food fresh. The temperature controller can always control the temperature inside the refrigerator within a specific range. When the temperature is higher than the specified range, the thermostat can automatically cool down.

Q1: What is a temperature controller?
A1: A thermostat is a series of automatic control elements that generate certain special effects by physical deformation inside the switch according to the temperature change of the working environment, resulting in an on or off action, also called temperature control switch, temperature protector, temperature controller, or thermostat for short. Or through the temperature protector will be temperature to the temperature controller, temperature the controller issues a switch command, so as to control the operation of the equipment to achieve the desired temperature and energy-saving effect.
Q2: What is the working principle of a temperature controller?
A2: Its working principle is to automatically sample and instantly monitor the ambient temperature through the temperature sensor, and the control circuit starts when the ambient temperature is higher than the control setpoint, and the control return difference can be set. If the temperature is still rising, the over-limit alarm function is activated when it rises to the set over-limit alarm temperature point. When the controlled temperature can not
be effectively controlled, in order to prevent the destruction of the equipment can also stop the equipment to continue to run through the function of tripping. It is mainly used in various high and low-voltage switchgear, dry-type transformers, box-type substations, and other related temperature fields used in the electric power sector.
Q3: What is the temperature controller used for?
A3: Digital electronic temperature controller is a precision temperature detection controller, that can be digital quantitative control of temperature, temperature controller is generally used NTC thermal sensor or thermocouple as the temperature detection element.
Tips: What is a relay output?
The relay output is an on/off output, which outputs 0 and 1 through on and off states. although relay output can be directly connected to PLC, it should be noted that the relay is mechanical and has a low speed. So it is not suitable for use at high-speed signals. Also, the relay output is an ON/OFF output, which is not suitable for continuously changing analog signals. In addition, the relay is just a switch. When pull-up or pull-down is required, voltage input cannot be used directly, and pull-up and pull-down resistors are required.
