Antunes Controls 803112802 Pressure Switch

The Antunes Controls 803112802 is a high-performance RHGP-A high gas pressure switch engineered for precision monitoring in industrial and commercial combustion systems. Designed with an adjustable set point range of 5-28" W.C., this SPDT pressure switch provides reliable automatic reset functionality, ensuring consistent operation without manual intervention after a pressure trip. It features a standard 1/4" NPT process connection for straightforward mounting and a 1/8" NPT vent for required atmospheric referencing. The rugged construction makes it ideal for gas train safety applications where monitoring high-limit thresholds is critical for burner management. This switch is frequently utilized in boilers, furnaces, and ovens to prevent hazardous over-pressure conditions. By maintaining tight tolerances and high repeatability, the 803112802 ensures the HVACR system safety and compliance with rigorous industrial standards, providing professional contractors with a dependable solution for gas pressure monitoring and control.

• Adjustable Range: Provides flexibility for field calibration between 5" and 28" water column for varied application requirements.
• SPDT Switch Logic: Single Pole Double Throw (SPDT) configuration allows for versatile wiring options for alarm or control circuits.
• Industrial Durability: Robust housing designed to withstand the vibration and temperature fluctuations common in mechanical rooms.
• Auto Reset Mechanism: Eliminates the need for manual resets, streamlining operation in automated combustion sequences.
• Standardized Ports: 1/4" NPT inlet and 1/8" NPT vent simplify integration into existing commercial gas trains.

What is the difference between an RHGP-A and an RHGP-M switch?
The RHGP-A (like this 803112802 model) features an auto reset function, while the RHGP-M requires a manual reset by a technician once the pressure condition has been cleared.

Can this switch be used for sensing air pressure?
While primarily designed as a high gas pressure switch, it is compatible with air and other non-corrosive gases; however, always verify system-specific flow media against the manufacturer's chemical compatibility charts.

Is the set point factory-locked or field-adjustable?
The 803112802 is fully field-adjustable within the 5-28" W.C. range using the internal adjustment dial located under the protective cover.
