消防系统压力表需要年检吗

一、仪表概述:
上自仪磁助式电接点压力表不仅具有设计新颖、结构可靠、品种齐全、动作稳定型好、适应性强的特点外,而且又具有测控并茂、安装简单、维护量小等优点,因此,它是一般无指示、无切换差调整和无外设定装置的压力控制器所无可比拟的压力测控仪表。
二、测量原理:
上自仪磁助式电接点压力表的由测量系统、指示系统、磁助电接点装置、外壳、调整装置和接线盒(插头座)等组成。
仪表的工作原理是基于测量系统中的弹簧管在被测介质的压力作用下,追使弹簧管之末端产生相应的弹性变形一位移,借助拉杆经齿轮传动机构的传动并予放大,由固定齿轮上的指示(连同触头)逐将被测值在度盘上指示出来。与此同时,当其与设定指针上的触头(上限或下限)相接触(动断或动合)的瞬时,致使控制系统中的电路得以断开或接通,以达到自动控制和发信报警的目的。
