Honeywell C6097A3095 Gas Pressure Switch
The Honeywell C6097A3095 is a high-precision pressure switch designed for monitoring gas, air, or flue gas in industrial combustion and HVAC systems. This versatile safety device can detect positive pressure, vacuum (negative pressure), or differential pressure, making it a critical component for boiler fan monitoring and gas train safety.
This model is engineered to “Break on Fall,” meaning it will open the electrical circuit if the pressure drops below your setpoint—an essential feature for low gas pressure cut-off (LGPCO) and safety interlock strings.
Key Features
Precise Monitoring: Monitors positive pressure of gas, biogas, and air, as well as negative or differential pressure of air and flue gas.
Break on Fall Action: Automatically switches off or triggers an alarm when pressure decreases below the designated switching point.
Easy Calibration: Features an integrated setting dial, allowing for quick and accurate switching point adjustments without specialized tools.
High-Quality Contacts: Equipped with silver contacts rated for 24–250 VAC, supporting a current range of 0.05 to 5A.
Rugged Construction: Silicon-free design ensures compatibility with sensitive industrial processes and prevents contamination.
Certified Safety: UL Listed, FM Approved, and RoHS Compliant, meeting the rigorous standards required for industrial firing and ventilation systems.
