The Series DX is a Differential Pressure Switch that makes a contact output based on the differential between two pressure sources. Wetted Materials of Brass and Fluoroelastomer are suitable for use with most Gases and Water-based solutions. Standard is a Weatherproof, UL type 4X, an enclosure for dust-laden, outdoor, or wash-down installation environments. Series DX incorporates an externally adjustable set point, integral mounting flange and a removable electrical terminal block for quick and easy installation. The DX uses opposing diaphragms to sense the high and low pressure with a pivot mechanism that transfers the difference of the two pressures to the SPDT Switch.

Product Applications:

Indicating Filter Differential Pressure. For example initiating Water Filter backwash as the filter becomes clogged on increasing Differential Pressure.Proof of flow indicator monitoring differential pressure from a sensing device. For example sensing the pressure across an orifice plate to prove water flow.Proving flow through a pump by sensing the pressure across the pump to make sure the pump does not run dry.Proving flow through a chiller. Often called evaporator water pressure drop.Proving flow through a heat pump or AC unit. Often called a condenser water lock-out switch.
