Antunes Controls 8102111304 Pressure Switch

The Antunes Controls 8102111304 is a specialized RHGP-G High Gas Pressure Switch designed for precise monitoring in industrial and commercial HVACR applications. This automatic reset pressure switch features an adjustable set point range of 5 to 35 inches water column, making it a critical component for safeguarding gas-fired equipment against over-pressure conditions. Engineered with a Single Pole Double Throw (SPDT) switch configuration, it provides versatile wiring options for both control circuits and alarm indicators. The unit integrates a standard 1/4" NPT connection, ensuring compatibility with common fuel gas manifolds and sensing lines. Built for high-reliability environments, the high gas limit switch prevents unsafe operation by interrupting the burner circuit if gas pressure exceeds the calibrated limit. This rugged field-adjustable control is frequently utilized in boiler systems, industrial ovens, and commercial heating units where maintaining specific WC pressure settings is essential for system integrity and combustion efficiency.

• Adjustable Range: Provides a broad 5-35" WC set point range for precise field calibration.
• SPDT Circuitry: Allows for simultaneous control of the primary load and external monitoring systems or alarms.
• Automatic Reset: Returns to normal operation once pressure falls below the set point, reducing downtime.
• Durable Construction: Designed to withstand the rigors of mechanical rooms and industrial gas trains.
• Standard Fitting: Features a 1/4" NPT inlet for straightforward installation on existing gas headers.

How do I adjust the trip point on the Antunes RHGP-G?
The set point is adjusted by removing the top cover and turning the adjustment screw to the desired inches water column setting indicated on the internal scale.

What is the function of the SPDT switch in this application?
The SPDT contact configuration allows the technician to break the main ignition circuit while simultaneously closing a secondary circuit to trigger a remote status light or building automation system (BAS) notification.

Can this switch be used for sensing air pressure?
While functionally similar to air switches, the 8102111304 is specifically rated and constructed for gas pressure monitoring; always verify fluid compatibility with the manufacturer's technical datasheet before installation.
