Antunes Controls 803112704 Pressure Switch

The Antunes Controls 803112704 Pressure Switch is a high-performance RLGP-A series low gas pressure switch engineered for precision monitoring in commercial and industrial combustion systems. This automatic reset gas switch is designed to trip when gas pressure drops below the calibrated set point, featuring an adjustable sensing range of 10-50" W.C. to ensure burner safety and equipment protection. Built with a rugged die-cast aluminum housing, it utilizes an SPDT switch configuration to provide reliable electrical logic for control circuits in gas-fired furnaces, industrial ovens, and commercial boilers. The unit includes a 1/4" NPT gas inlet and a 1/8" NPT vent connection, facilitating a standard interface for HVACR technicians during field installation or OEM replacement. Rated for high-cycle industrial use, the 803112704 pressure sensor maintains UL, FM, and CSA approvals, making it a critical safety component for maintaining optimal performance in high-demand gas-fired equipment and preventing low-pressure flame instability.

• Adjustable Sensing Range: Precise field adjustment between 10" and 50" W.C. for versatile system integration.
• Automatic Reset Logic: Eliminates manual intervention by restoring the electrical circuit once the gas pressure recovers to safe operating levels.
• Industrial Duty Construction: Durable aluminum housing designed to withstand harsh ambient temperatures ranging from -40°F to 140°F.
• Versatile SPDT Contacts: Supports multiple wiring configurations for flexible control circuit safety interlocks.
• Ease of Installation: Standard NPT threaded connections for quick replacement in existing combustion manifolds.

What is the maximum surge pressure for this switch?
The Antunes RLGP-A series is designed to handle a maximum surge pressure of up to 10 PSI without damage to the internal diaphragm.

Can this pressure switch be mounted in any orientation?
For maximum accuracy and to maintain calibrated set points, it is recommended to mount the switch in a vertical position with the conduit entry facing down.

Is this switch suitable for outdoor gas-fired equipment?
Yes, its wide operating temperature range and rugged housing make it suitable for various environments; however, ensure the electrical connections are protected from direct liquid ingress.
