Antunes Controls 803114102 Pressure Switch

The Antunes Controls 803114102 Pressure Switch is a high-performance low gas pressure switch engineered for critical monitoring in industrial combustion systems and commercial HVACR applications. Operating within a 10-50" W.C. (water column) range, this RLGP-D model features an auto reset mechanism and a DPDT (Double Pole Double Throw) switch configuration, allowing for simultaneous control of two independent circuits. Designed for rugged environments, it utilizes a die-cast aluminum housing and a 1/4" NPT connection with a 1/8" NPT vent. This gas pressure safety switch effectively breaks the electrical control circuit if pressure drops below the user-defined setpoint, preventing equipment damage and ensuring operational safety. Technicians appreciate the 803114102 for its repeatability and its ability to be mounted horizontally without requiring precision leveling. It is rated for a maximum surge pressure of 10 PSI and functions reliably in temperatures ranging from -40°F to 140°F.

• Dual Circuit Control: The DPDT configuration allows the Antunes 803114102 to manage two separate voltages or signals upon pressure drop.
• Automatic Reset: Eliminates manual intervention by resetting the circuit once gas pressure returns above the setpoint.
• Heavy-Duty Construction: Built with a rugged die-cast aluminum housing to withstand industrial combustion environments.
• Flexible Installation: Features standard 1/4" NPT bottom inlet and can be mounted without hyper-accurate leveling.
• Broad Operating Range: Adjustable 10-50" W.C. range provides versatility for various low gas pressure monitoring requirements.

What is the difference between RLGP-D and standard LGP models?
The RLGP-D (like the 803114102) features a DPDT switch for controlling two circuits, whereas standard LGP models typically utilize an SPDT arrangement. The "R" designates its auto reset functionality.

Does this switch require a specific mounting orientation?
For optimal repeatability, Antunes recommends mounting the switch horizontally with the inlet stem pointed downward. It does not require precision leveling for accurate gas pressure monitoring.

Can the 803114102 handle high-pressure surges?
Yes, this unit is rated for a maximum surge pressure of 10 PSI, though its functional low gas pressure setpoints are restricted to the 10-50" W.C. scale.
