ĐỒNG HỒ ĐO ÁP SUẤT CÓ TIẾP ĐIỂM ĐIỆN INSTRUMATE MODEL 213

In industrial processes, there are times when you need to read the pressure values and at the same time have the ability to alter electric circuits (open/close) at desired set values. In case the media demands a stainless steel instrument, then InstruMate model 213 electric contact pressure gauges are the right choice. Contact-Mate 213 is a heavy duty pressure gauge with switch contacts of snap-action type.

InstruMate electric contact gauges 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, InstruMate Electric switch gauges come in handy.

Having them put into correct application, InstruMate Electric Contact Gauges with their robust design are a reliable choice fo switching  functions (normally closed, normally open, and change-over contacts).

Setpoint for contacts are adjusted easily by the use of a key supplied with the product and free movement of the value-pointer is guaranteed regardless of the setpoints.
