威卡电接点压力表 法兰式PGS23.100+821.22+990.27
描述
无论何种情况下，如果您希望在本地显示过程压力的同时，对电路进行通断操作，switchGAUGE系列的PGS21.1x0型压力表将是理想选择。
开关电接点（报警用电子式电接点）可根据仪表的指针位置接通和关断电气控制电路。开关电接点在全量程范围内可调（参见DIN 16085）。通常情况下，电接点都安装在表盘下面，只有少数是安装在表盘上面。仪表指针（实际值指针）可在整个量程范围内自由旋转，与设定无关。
设定指针可以通过窗口内的可拆卸调整键进行调整。
开关电接点不仅包含多个电接点，而且可以设置单个设定值。当实际值指针过或低于设定值时，电接点便会进行切换。
该型号压力表根据DIN 16085标准制造，并且符合所有相关标准（如EN 837-1）和规范的安全要求，完全可用于现场测量高压容器的工作压力。
开关电接点包括磁助式电接点、感应式电接点和电子式电接点，其中磁助式和感应式电接点符合ATEX要求，电子式电接点通用于触发PLC。
