Dwyer Instruments 1823-00 Pressure Switch
The Dwyer Instruments 1823-00 Pressure Switch is a industrial-grade solution designed for precision monitoring of air and non-combustible gases in HVAC systems. Covering a set-point range of 0.07" to 0.22" w.c., this differential pressure switch is essential for verifying fan status, filter efficiency, and low-airflow conditions. It features an approximate deadband of 0.05", ensuring stable operation without excessive cycling in turbulent environments. Built for durability, the low differential pressure switch supports a 10 psig maximum pressure limit and utilizes standard 1/8" female NPT connections for seamless integration into existing pneumatic lines. For technicians managing building automation systems, the Dwyer 1800 series remains the industry standard for air pressure sensing due to its field-proven diaphragm design and repeatable set points. Whether you are troubleshooting air handler units or ensuring proper static pressure in ductwork, this HVAC pressure switch provides the reliability required for critical commercial and industrial applications.
Key Benefits- Precise Set-Point Adjustment: The 0.07" to 0.22" w.c. range allows for fine-tuning in low-flow environments.
- Compact Footprint: Designed for easy mounting in tight mechanical rooms and control cabinets.
- Rugged Construction: Durable housing handles a maximum pressure limit of 10 psig without compromising calibration.
- Universal Compatibility: Standard 1/8" NPT threads and versatile electrical ratings simplify field replacements.
What is the maximum operating temperature for the Dwyer 1823-00?
The 1800 series is typically rated for ambient temperatures between -30 to 180°F, making it suitable for unconditioned mechanical spaces.
Can I use this switch for combustible gas applications?
No, the 1823-00 is strictly rated for air and non-combustible gases. Using it with hazardous gases can lead to component failure.
How do I adjust the set point in the field?
The set point is adjusted via an internal screw; it is recommended to use a calibrated manometer to ensure accuracy during commissioning.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
