Dwyer Instruments 1823-40 Pressure Switch
The Dwyer Instruments 1823-40 Pressure Switch is a high-performance low differential pressure switch engineered for general industrial service where compact form factors and reliable repeatability are required. This SPDT pressure switch features an adjustable operating range from 5" w.c. to 44" w.c., making it ideal for monitoring air and non-combustible gases in mechanical equipment control and process applications. It maintains a ±2% repeatability across most settings, with an approximate deadband ranging from 0.56" w.c. at the minimum set point to 1.10" w.c. at the maximum. Designed for versatility, the 1823-40 utilizes 1/8" female NPT connections and a screw-type set point adjustment located inside the mounting spud, allowing for easy access when panel or wall-mounted. With a 15A electrical rating at 120-480 VAC and a 10 psig continuous pressure limit, this unit provides a robust solution for HVACR technicians seeking a durable, industrial-grade Dwyer 1800 series alternative for precise pressure monitoring.
Key Benefits- Precise Switching: Delivers 2% repeatability for consistent performance in critical industrial differential pressure monitoring.
- Versatile Mounting: The internal set point adjustment allows for clean installations on walls or panels with adjustment accessibility from the opposite side.
- Broad Compatibility: Rated for 15 Amps at up to 480 VAC, supporting a wide variety of electrical loads and motor control circuits.
- Rugged Construction: Capable of withstanding a 10 psig continuous pressure limit and up to 25 psig surge without compromising the diaphragm-operated mechanism.
How do I adjust the set point on the 1823-40?
The set point is adjusted via a screw-type mechanism located inside the mounting spud. This design allows for the switch to be mounted on one side of a panel while remaining adjustable from the other.
What is the proper mounting orientation for this switch?
For maximum accuracy and to maintain calibrated set points, the switch must be mounted with the diaphragm in a vertical position. Mounting in other orientations may require recalibration.
Can this pressure switch be used with combustible gases?
No, the 1823-40 is strictly designed for use with air and non-combustible, compatible gases. Contact our technical team if you require a switch for hazardous or combustible media.
