Dwyer Instruments 1900-10MR Pressure Switch
The Dwyer 1900-10MR is a precision-engineered low differential pressure switch designed for critical monitoring of air and non-combustible gases. As part of the 1900 series, this model offers a versatile set point range of 3.0" to 11.75" w.c., making it a staple for contractors managing high-limit applications where safety and system integrity are paramount. The manual reset functionality ensures that any pressure excursion beyond the set point remains flagged until a technician performs a manual intervention, preventing hazardous cycling in HVAC duct static pressure or positive pressure cleanroom environments. Featuring a diaphragm-operated SPDT snap switch, this unit integrates seamlessly into automated building control systems. The silicone diaphragm provides excellent sensitivity and repeatability, while the compact enclosure fits easily into standard industrial pressure transmitter layouts. For field service pros, the Dwyer 1900 series wiring is straightforward, allowing for rapid installation and reliable differential pressure switch 1900-10MR replacement in existing commercial HVAC airflow monitoring assemblies.
Key Benefits for the Technician- Manual Reset Mechanism: Critical for safety interlocks, ensuring the system remains locked out after a trip until personally inspected.
- Precise Set Point Control: The calibrated scale allows for exact pressure switch adjustment within the 3.0" to 11.75" w.c. range.
- Durable Construction: Built with a silicone diaphragm and an acetal plastic housing to withstand standard mechanical room conditions.
- High Compatibility: Designed for use with air and non-combustible gases, making it the standard choice for cleanroom pressure monitoring.
Is the 1900-10MR suitable for outdoor use?
The standard 1900-10MR is intended for indoor applications. For outdoor installations or harsh environments, a weather-tight enclosure or NEMA 4 rated housing is recommended.
How do I plumb the high and low pressure ports?
Connect the high pressure line to the 'High' port and the low pressure or atmospheric reference to the 'Low' port using 1/8" NPT female connections. For vacuum sensing, the 'High' port should be vented to atmosphere.
Can this switch be used to monitor combustible gas lines?
No. This unit is strictly rated for air and non-combustible gases. Use an explosion-proof or intrinsically safe enclosure for combustible environments.
