Baby origin: Guangdong, Shenzhen. Brand product quality is guaranteed
Principle, performance and Application
Principle performance: when the temperature of the controlled object changes, the working substance in the temperature sensing part of the temperature controller produces the corresponding physical phenomenon of expansion and contraction (the volume change of the working substance), and the bellows which are connected with the temperature sensing part produce expansion or contraction. Through the lever principle, drive switch on-off action, to achieve the purpose of constant temperature. WZ series liquid expansion temperature controller has the characteristics of accurate temperature control, stable and reliable, small temperature difference between open and stop, large temperature control range, high overload current and so on.
Uses: mainly used in household appliance industry (shower, drum type washing machine, heater, electric heating equipment (stainless steel) automatic boiling water heater, electric fryer, food machinery, medical equipment, refrigeration industry) (fresh cabinet, kitchen freezer, refrigerator, ice machine, fish pond, cold drink machine, heater temperature control etc.) use.
