Antunes Controls 803112801 Pressure Switch

The Antunes Controls 803112801 (Model RHGP-A) is a specialized high gas pressure switch designed for critical monitoring in industrial and commercial combustion systems. This auto reset SPDT switch operates within a precise range of 2-16" W.C., ensuring high-limit protection for gas trains. Engineered for durability, it features a 1/4" NPT process connection and a 1/8" NPT vent port, facilitating seamless integration with existing piping. The SPDT electrical configuration allows for versatile signaling, enabling the controller to bridge a circuit or trigger an alarm upon sensing pressure exceeding the designated set point. Veteran technicians rely on the Antunes 803112801 for its repeatable accuracy and robust diaphragm construction, which resists common contaminants found in natural gas and propane applications. This gas pressure safety switch is essential for maintaining compliance with safety codes and protecting downstream components from over-pressure conditions in boilers, furnaces, and ovens.

• Field-Adjustable Set Point: Features a clear scale for precise calibration between 2" and 16" water column.
• Automatic Reset Logic: The RHGP-A resets automatically once pressure drops below the set point, minimizing downtime.
• Compact NPT Ports: Standardized 1/4" and 1/8" connections simplify field replacement and retrofitting.
• Rugged Housing: Designed to withstand the high-cycle demands of industrial gas burner manifolds.

Is the Antunes 803112801 suitable for outdoor installation?
The RHGP-A series is typically designed for protected environments; ensure the enclosure rating matches your specific job site requirements or utilize a weather shield.

Can this switch be used for low gas pressure sensing?
No, this model is a high gas pressure switch. For low-limit monitoring, a dedicated low gas pressure switch with a manual or auto-reset function should be specified.

What is the maximum surge pressure for this unit?
While the operating range is up to 16" W.C., these units are typically rated for a maximum surge pressure of 15 PSI to prevent diaphragm rupture.
