- Supports CU50/PT100/K/E/J/T/S/R temperature sensors
- Support 4-20 mA /0-10mA/ 1-5v/0- 10v/0- 5v current signal.
- Double-row four-digit digital tube display, four keys to operate the temperature control meter, display the measured value and the set value at the same time.
Control mode arbitrary switching
- Control mode has upper and lowers limit control, and PID controls two ways to switch at will.
- PID control has a parameter self-tuning function, which can achieve accurate measurement and efficient thermostats for temperature, pressure, flow, etc.
- The PID control has a parameter self-tuning function, which can achieve accurate measurement and efficient constant temperature and pressure control.
Temperature controllers are widely used in various home appliances, such as water dispensers, water heaters, etc. 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 certain 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 the meaning of PID in a temperature controller?
In a temperature controller, PID control is the setting of the parameter P to a non-zero value (setting the parameter P to zero is called ON/OFF control). The PID controller regulates the heater to change the measured value (PV), which is compared with the set value (SV) to obtain the deviation value (EV = SV - PV). The deviation value (EV) is fed back to the PID controller through the sensor, and the PID controller calculates the next adjustment of the heater on. The PID control system is a closed-loop control, and the heating equipment can work at different powers. In all time periods, the actual value and the set value are infinitely close to each other. Theoretically, it is possible to achieve error-free control between the actual temperature and the set temperature.
