New air conditioning units at both ends of the filter differential pressure switch is why platinum and rhodium thermocouple, without using pressure (difference) sensor, what is the difference between the two, in the selection of which is connected at different pressures attention generated by the elastic deflection of the diaphragm pressure . This special diaphragm ensures long-term stability of the transition point. Each model is engraved with a separate scale for high precision adjustable temperature thermocouple, Youbisheng electromechanical, Gansu thermocouple provided by Changzhou gifted Litas Electrical Co., Ltd. established.
