Dwyer Instruments 1950-10-2F Pressure Switch
The Dwyer Instruments 1950-10-2F Pressure Switch is a rugged, compact solution designed for contractors managing differential pressure monitoring in hazardous environments. This unit integrates the reliable switching of the 1900 series into a specialized explosion proof housing, rated for Class I, Div. 1, Groups C and D, as well as Class II and III atmospheres. With an adjustable range of 3 to 11 inches w.c., it provides precise control for air and non-combustible gases. The SPDT switch configuration, rated at 15A, allows for flexible normally open or normally closed wiring via internal screw terminals. Maintenance is streamlined by an external set point adjustment screw, permitting field calibration without violating the NEMA 7 or NEMA 9 enclosure seal. Built with a 1/8 inch female NPT process connection and a weatherproof O-ring seal, this NEMA 3 raintight device ensures long-term performance in demanding HVAC and industrial process applications.
Key Benefits- Dual-Rated Protection: Certified as both explosion-proof and weatherproof, eliminating the need for separate housings.
- Enhanced Deadband Stability: Maintains an approximate deadband of 0.40 at the minimum set point and 0.50 at the maximum for consistent switching.
- Streamlined Installation: Compact design is nearly half the weight of traditional explosion-proof switches, easing vertical mounting requirements.
- Simplified Calibration: Adjust the pressure set point using the top-mounted screw without opening the front cover.
Is the 1950-10-2F suitable for outdoor use?
Yes, the housing is NEMA 3 (IP54) rated and includes a drain plug and O-ring seal, making it suitable for rain-tight, all-weather installations.
What media can be used with this differential pressure switch?
It is designed exclusively for clean, dry air and non-combustible, compatible gases. It is not recommended for combustible gas media on the low-pressure port.
Can it be mounted in any orientation?
For specified accuracy and proper reset function, the switch must be mounted with the diaphragm in a vertical plane and the nameplate upright.
