ĐỒNG HỒ ĐO ÁP SUẤT CÓ TIẾP ĐIỂM ĐIỆN INSTRUMATE MODEL 212

212 Contact-Mate electric contact gauges have a brass connection and and stainless steel case, making them the economic choice for most industrial switching demands.

Contact-Mate products are a group of InstruMate electric contact gauges that open or close electric circuits depending on the position of the indicating pointer. So if pressure value monitoring and switching application are needed at the same time, a Contact-Mate comes in handy.

In the case of a normally-open function, the rising pressure value pointer takes the contact arm with it, thus closing the circuit when the set-point is exceeded.

In the case of a normally-closed function, the rising actual-value pointer takes the contact arm with it, thus interrupting the circuit when the set-point is exceeded.
