描述

所有需要在本地显示过程压力、同时又必须切换电路的应用都可以使用532.5x型开关触点压力表。

开关触点（也称“报警触点”）会根据显示测量仪表的指针位置接通或断开控制电路。可以在满量程范围内调节开关触点（参见DIN 16085），此类触点主要安装在表盘下方，有些安装在表盘顶部。仪表指针（实际值指针）可在整个量程范围内自由转动，不受设置的影响。

可在窗口内使用可移除式调节钥匙对指针进行调节。

可将包含多个触点的开关触点设置至一个设***。当实际值指针超出或低于所需的设***时，触点就会被激活。

该压力计根据DIN 16085标准制造而成，满足相关标准(EN 837-3)的所有要求以及现场显示压力容器工作压力的有关规定。

根据ATEX的相关要求，可以选择使用开关触点、磁助式电接点、舌簧开关和电感式电接点或电子式接点来触发PLC。
