differential pressure switch for water pump

Specifications ; Electromechanical pressure switch · Fresh water (-30125 °C) · 172.37551.58 kPa · 137.90206.84 kPa · 1516.85 kPa.

Using a differential pressure sensor will enable the VFD to modulate the pump speed to track the 2 way valve position. A pressure sensor has no way to track the valve position as it is only looking at static pressure which can be influenced by fill pressure, expansion tanks, leaks, etc.

A differential pressure switch compares two pressures and acts on the difference. When the set differential pressure is exceeded, the contact system activate

These switches are rated NEMA 4 for protection from dirt and washdowns. They operate based on the difference in pressure between two process lines. When the differential pressure exceeds your setpoint, the switch is activated. Often used to indicate clogged filters, they are designed to automate controls or activate an alarm in your process. Switches are single pole,
