Dwyer Instruments 1950-00-2F Pressure Switch

Dwyer Instruments 1950-00-2F Pressure Switch

The Dwyer Instruments 1950-00-2F Pressure Switch is a specialized solution for monitoring low-range differential pressure in hazardous environments. Engineered to detect set points between .07 to .15" w.c., this unit integrates the proven mechanics of the 1900 series with a compact, explosion-proof housing. The lightweight anodized aluminum enclosure provides robust protection for the SPDT switch, which is rated for 15A at up to 480VAC. For technicians in the field, the external set point adjustment screw is a critical feature, allowing for precise calibration without breaching the NEMA 7 or 9 enclosure. Designed for use with air and non-combustible gases, the 1950-00-2F utilizes a vertical diaphragm orientation and 1/8" female NPT process connections to ensure a reliable approximate deadband of .04 to .05". Its weatherproof design, complete with a drain plug and O-ring seal, makes it suitable for demanding HVACR and industrial process applications where volatile atmospheres are a factor.

Key Benefits
  • Explosion-Proof Protection: Compact housing is UL, CSA, and FM approved for Class I, Div 1 (Groups C, D) and Class II (Groups E, F, G) hazardous locations.
  • External Calibration: Adjust set points via the top-mounted screw without opening the housing, maintaining the internal seal during maintenance.
  • High Electrical Capacity: The SPDT relay handles up to 15A, providing versatile control for fans, dampers, and alarm systems.
  • Environmental Resilience: Features a raintight NEMA 3 (IP54) rating with a dedicated drain plug for outdoor or washdown installations.
  • Lightweight Design: Significantly smaller and lighter than traditional explosion-proof switches, simplifying mounting in tight mechanical spaces.
Common Questions

Is the Dwyer 1950-00-2F compatible with natural gas?
No, this specific model is designed for air and non-combustible, compatible gases. For combustible gas applications, the 1950G series should be specified.

How do I adjust the deadband on this switch?
The deadband on the 1950-00-2F is a fixed characteristic of the diaphragm and switch mechanism, approximately .04" at the minimum set point and .05" at the maximum.

Can this pressure switch be mounted in any orientation?
For accurate switching at the .07 to .15" w.c. range, the unit must be mounted with the diaphragm in a vertical plane. Consult factory specifications for other mounting positions.
