Fireye FGPS-GMH-0120 Switch

The Fireye FGPS-GMH-0120 is a heavy-duty manual reset high pressure switch designed for critical monitoring of air, LP gas, or natural gas pressures in industrial combustion systems. Featuring a calibrated range of 1 to 20 inches water column, this diaphragm-operated switch ensures precise setpoint accuracy for safety interlocking. The NEMA 4 rated enclosure provides superior protection against water ingress and dust, making it suitable for demanding boiler room environments. Engineered for reliability, the SPST normally closed contacts open when pressure exceeds the manual setpoint, requiring a physical reset to resume operation. This gas pressure limit switch utilizes a 1/4" NPT connection for seamless integration into standard manifolds. By monitoring for overpressure conditions, the FGPS-GMH-0120 serves as a vital component in preventing hazardous fuel-rich conditions or mechanical damage to burner assemblies and gas trains.

• Precise Pressure Monitoring: Adjustable 1-20" WC range allows for exact calibration to technical specifications.
• Rugged Durability: NEMA 4 housing ensures the Fireye pressure switch performs in harsh industrial applications.
• Enhanced Safety: Manual reset functionality prevents automatic restarts until the technician verifies the fault condition.
• Universal Compatibility: Standard 1/4 inch NPT threading for easy field replacement in HVACR gas trains.

What is the maximum operating pressure for the FGPS-GMH-0120?
This switch is rated for a maximum pressure of 15 PSI (1034 mbar) to ensure integrity across high-flow commercial burner applications.

Can this switch be used for differential pressure sensing?
The FGPS-GMH series is primarily designed as a single-point high gas pressure switch manual reset for safety interlock circuits.

Is the setpoint adjustable in the field?
Yes, the internal scale allows for direct adjustment between 1" and 20" WC, providing flexibility for specific burner manifold requirements.
