PS75 系列压力开关
坚固的圆柱型压力开关
概述/设计原理:
Gems PS75系列具有全金属表面以限制过载，在高压波动的环境下仍能出色的工作。内部设计耐磨盘和减震环以延长寿命。还采用活塞/隔膜设计，集活塞技术的耐高压特性和隔膜技术的高灵敏度于一身。现场可调或工厂设定.

* In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
** Operation of both switches in most cases will not be simultaneously but will occur within the specifications listed. Deadband figures already reflect the improvement from the -RD option which is automatically included in the -AA, -BB, and -CC circuits.
