Antunes Controls 8102111102 Pressure Switch

The Antunes Controls 8102111102, model RHGP-G, is a precision-engineered High Gas Pressure Switch designed for monitoring gas manifolds in commercial burner systems. This SPDT high gas pressure switch features an adjustable range of .8 to 4 inches water column (W.C.), ensuring reliable safety interlocking for gas-fired equipment. With an auto reset mechanism and a standard 1/4 inch NPT connection, this switch provides accurate sensing for natural gas, propane, and air applications. Field technicians rely on the RHGP-G for its rugged construction and repeatable setpoints, making it a critical component for industrial combustion safety and HVAC flame safeguard circuits. The Antunes 8102111102 is built to withstand high-demand cycles, providing high-limit protection by breaking the electrical circuit when gas pressure exceeds the calibrated threshold, preventing hazardous operating conditions in commercial boilers and process heating systems.

• Precise Pressure Regulation: Adjustable .8 to 4" W.C. range allows for exact calibration to specific burner requirements.
• Versatile Compatibility: Rated for use with air and various fuel gases, suitable for diverse gas pressure switch replacement needs.
• Automatic Reset Functionality: Minimizes downtime by automatically restoring the SPDT circuit once pressure returns to safe operating levels.
• Durable NPT Connection: Features a 1/4" NPT process connection for secure, leak-free installation in standard gas trains.

Common Questions

What is the maximum surge pressure for this switch?
The RHGP-G series is typically rated for a maximum surge pressure of 15 psi, but always verify specific manifold pressure against the technical data sheet to prevent diaphragm damage.

Can this switch be used for low gas pressure applications?
No, the 8102111102 is specifically calibrated as a high gas pressure switch. For low-limit sensing, an RLGP model should be sourced to ensure proper safety sequencing.

How do I verify the current setpoint?
Technicians should use a calibrated manometer to adjust the internal scale, ensuring the automatic gas pressure switch trips at the exact desired water column value.
