VACUUMSWITCH压力开关产品的激励电源分为正比激励和固定激励。前者是将压力传感器电桥直接接到电源上，当电源改变时，压力传感器的灵敏度和零点都随之发生变化。后者内部有一个参考电压，压力传感器电桥由参考电压供电激励。参考电压是恒定的，与电源无关。只要电源电压在一X电压范围内变化，参考电压不变。因而传感器的输出不变，不受电源电压的影响。
VACUUMSWITCH压力开关产品是当系统内压力高于或低于额定的安全压力时，感应器内碟片瞬时发生移动，通过连接导杆推动开关接头接通或断开，当压力降至或升额定的恢复值时，碟片瞬复位，开关自动复位，或者简单的说是当被测压力X过额定值时，弹性元件的自由端产生位移，直接或经过比较后推动开关元件，改变开关元件的通断状态，达到控制被测压力的目的。压力开关采用的弹性元件有单圈弹簧管、膜片、膜盒及波纹管等。常见的使用范围有电力、石油、化工、冶金、锅炉、食品机械、环保设备等行业。
