US UE pressure switch 400-126 J400-134 J400-137 J400-144 J400-146 J400-156 J400-164 application   The 400 series pressure switch is a multi-purpose series switch, especially suitable for when multiple output and control are required. Two-point and three-point settings provide multi-point output, which can be used for alarm and shutdown, early warning and alarm, high/low limit and liquid level control functions.  All-weather series switches have a variety of micro switches and a variety of process interface options, so that the 400 series switches can meet various needs. Due to its own characteristics, the 400 series is widely used in protection and control, industrial process equipment and pumps, steam turbines, compressors, pulp and paper, water and sewage treatment and other industries.   .
