Antunes Controls 803112502 Pressure Switch

The Antunes Controls 803112502, model LGP-A, is a precision-engineered low gas pressure switch designed for critical monitoring in industrial and commercial combustion systems. It features a set point range of 2 to 14 inches Water Column (W.C.) and incorporates a manual reset mechanism, ensuring the system remains locked out after a low-pressure event until a technician manually clears it. This SPDT pressure switch is constructed with a durable diaphram and robust housing to withstand field conditions while maintaining high repeatability. The unit utilizes a 1/8" NPT connection for seamless integration into various gas manifolds. Whether you are performing a commercial boiler repair or replacing an aging Antunes gas pressure switch, this component provides the essential safety interlocking required for safe burner operation. Its compact footprint and reliable electrical contacts make it a standard choice for HVAC safety controls and combustion air or fuel gas monitoring applications.

Key Technical Benefits:

• Precise Set Point Control: Adjustable range from 2" to 14" W.C. allows for exact calibration to OEM specifications.
• Manual Reset Safety: Prevents automatic equipment restarts during fluctuating gas pressure conditions, enhancing overall system safety.
• Industrial Build Quality: High-tolerance internals ensure long-term stability and minimize nuisance tripping in combustion system maintenance.
• Versatile Compatibility: Standard electrical ratings and porting allow this Antunes 803112502 to replace a wide range of low gas pressure sensors.
• Clear Status Feedback: The Antunes LGP-A design provides clear mechanical feedback for field troubleshooting and diagnostics.

Common Technical Questions:

How do I calibrate the trip point on the LGP-A?
Use the internal adjustment screw to set the desired low gas pressure threshold, ensuring you verify the trip point with a calibrated manometer during commissioning.

Can this switch be used for high gas pressure applications?
No, the 803112502 is specifically designed as a low gas pressure switch; a high-pressure model with a different spring tension and configuration would be required for high-limit monitoring.

What is the purpose of the manual reset on this model?
The manual reset ensures that a technician must inspect the gas line or regulator issues before the combustion cycle is allowed to resume, adhering to strict safety protocols.
