Dwyer 1635-1-MIL 548783 T44P-S11662601 Differential Pressure Switch

Dwyer 1635-1-MIL is a differential pressure switch that detects a pressure difference and actuates an electrical contact when the sensed differential reaches its programmed range. This unit is identified by the part numbers 548783 and T44P-S11662601 in DWYER’s catalog and is listed as the 1635-1-MIL variant within the DWYER differential pressure switch family. The documented sensing range is.20-1.0, indicating the span over which the switch responds to differential pressure. As a DWYER product, it is part of a lineup used to monitor pressure differences and trigger control or alarm circuits in equipment and systems that rely on differential pressure sensing. The combination of the model designation, the MIL suffix, and the internal part numbers helps verify exact compatibility with existing DWYER installations and catalog references. Differential pressure switches are commonly employed in instrumentation and automation to provide automatic signaling, control, or safety interlocks in response to changing pressure conditions.
