机械压力开关工作原理:
压力开关的工作原理：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，碟片瞬时复位，开关自动复位，或者简单的说是当被测压力超过额定值时，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。
概要
400 系列压力,差压及温度开关是一种多用处的的系列开关，特别适用于需要多点输出和控制时。双点和 3 点设定提供多点的输出，可用于报警和关断，预警和报警，高/低限和液位控制功能。全天候系列开关有多种微动开关和多种过程接口的选择，使得 400 系列开关可以满足各种不同的需求。由于其自身的特性，400 系列广泛应用于保护与控制，工业过程装置及泵，气轮机，压缩机，纸浆和造纸，水及污水处理等行业。
