Dwyer Instruments 1910-0 Pressure Switch
As a core component for field technicians, the Series 1900 pressure switches are engineered for precision in low-pressure HVAC applications. The Dwyer 1910-0 Pressure Switch is a versatile differential pressure switch designed specifically for air and non-combustible, compatible gases. With an adjustable operating range of 0.15" to 0.55" w.c., this unit provides the high repeatability required for critical clogged filter detection and duct static pressure monitoring in commercial air conditioning systems. The SPDT switch mechanism allows for flexible wiring configurations (N.O. or N.C.), making it compatible with a wide variety of air volume controllers or alarm circuits. Built with a silicone diaphragm and metallic housing, it withstands a 45" w.c. continuous pressure limit. The set point adjustment screw is conveniently located inside the conduit enclosure to prevent unauthorized tampering in the field, ensuring long-term system stability and reliable HVAC pressure monitoring without the bulk of larger, more expensive units.
Key Benefits:- Precision Control: Features a low differential pressure range of 0.15" to 0.55" w.c. with a repeatability of ±3% for accurate performance.
- Rugged Reliability: Designed with a zinc-plated steel housing and high-grade silicone diaphragm to handle non-combustible gases and inert dry air.
- Tamper-Resistant Design: The internal adjustment screw protects your set points, crucial for maintaining calibrated air pressure sensing in high-traffic commercial environments.
- Universal Compatibility: Includes standard 1/8" female NPT process connections and 3-screw terminals for easy integration into existing mechanical systems.
- Safety Focused: Fully certified with UL, CSA, FM, and CE approvals for industrial and OEM standards.
How do I adjust the set point on the Dwyer 1910-0?
To adjust the pressure set point, remove the conduit enclosure cover. Turn the internal range screw clockwise to increase the set point or counter-clockwise to decrease it. For best results, mount the switch in a vertical position to maintain the factory calibration.
Can this switch be used for refrigerant leak detection?
No, the 1910 series is specifically for use with air or compatible gases. It is commonly used for filter pressure drop, coil icing detection, and defrost cycle initiation in air handling units, but it is not intended for use with corrosive or combustible refrigerants.
What is the maximum pressure this switch can handle?
The unit has a 45" w.c. continuous pressure limit. Exceeding this limit or experiencing significant surges beyond 10 psig may damage the internal silicone diaphragm and compromise the accuracy of the differential pressure sensor.
