Principle performance:
When the temperature of the controlled object changes, the working fluid in the temperature sensing part of the thermostat will produce corresponding thermal expansion and contraction (the volume change of the working fluid), and the diaphragm is connected with the temperature sensing part. Produce expansion or contraction. Through the principle of lever, the switch can be turned on and off to achieve the purpose of constant temperature. WGA series liquid expansion thermostat has the characteristics of accurate temperature control, stability and reliability, small temperature difference between start and stop, large temperature control adjustment range, overload current and other performance characteristics.
1: When the temperature rises to the required control temperature, the power will be automatically cut off (the appliance stops working), and when the temperature drops, the power will be automatically switched on (the appliance starts to work)
2: When the temperature rises, the power will be automatically turned on, and when the temperature drops to the required control temperature, the power will be automatically cut off”
Wiring method:
The thermostat has three wiring copper pieces, namely 1, 2, and C(P).
When C and 1 are connected in series on the power circuit, the temperature rises to the required control temperature.
When C and 2 are connected in series on the power circuit, the power will be automatically turned on when the temperature rises (the appliance starts to work).
When the temperature drops to the required control temperature, it will automatically cut off the power (the electrical appliances stop working).
Uses: Mainly used in the home appliance industry (showers, drum washing machines, heaters), electric heating equipment (stainless steel automatic water boiler, electric frying Pot, food machinery, medical equipment), refrigeration industry (kitchen refrigerator, fresh-keeping cabinet, cold storage, ice maker, fish pond, cold drink machine, heater), etc. to control temperature
