A.J. Antunes 8104116102 Pressure Switch

The A.J. Antunes 8104116102, model RLGP-G, is a precision-engineered low gas pressure switch designed for critical monitoring in industrial burner systems and HVAC applications. This auto reset pressure switch features a Single Pole Double Throw (SPDT) configuration, allowing for versatile wiring in safety limit circuits. Built to detect a drop in gas pressure below setpoints, it operates within an adjustable range of 0.5 to 4 inches Water Column (WC). The unit utilizes a standard 1/4 inch NPT connection for secure integration into existing manifold lines. It is constructed to withstand the rigors of mechanical rooms, providing high-repeatability switching for natural gas, propane, and air. Technicians rely on the RLGP-G series for its durable diaphragm design and electrical reliability in combustion control systems. Proper calibration of this gas safety switch ensures optimal fuel-to-air ratios and prevents equipment damage during low-pressure events.

• Precise Setpoint Control: Adjustable 0.5 to 4" WC range for fine-tuned pressure monitoring in sensitive gas trains.
• Automatic Reset Logic: Eliminates manual intervention by automatically restoring the circuit once gas pressure rises above the setpoint.
• Robust SPDT Contact: Provides flexibility for normally open or normally closed wiring depending on system interlocking requirements.
• Industrial Durability: NEMA rated components ensure longevity in environments prone to temperature fluctuations and vibration.

Common Technical Questions

What is the maximum operating pressure for the 8104116102?
This model is designed for a maximum surge pressure of up to 15 PSI, though it is optimized for low-pressure sensing between 0.5 and 4" WC.

Can this switch be mounted in any orientation?
For maximum accuracy and to maintain the specific setpoint, it is recommended to mount the diaphragm in a vertical position as calibrated by the manufacturer.

What media is compatible with the RLGP-G switch?
The internal components are compatible with natural gas, LP gas (propane), and air, making it suitable for a wide range of forced-draft burners.
