C6097A3004 Honeywell Pressure Switch

The Honeywell C6097A3004 pressure switch

Overview

The Honeywell C6097A3004 is a diaphragm-type pressure switch used to monitor gas or air pressure in combustion and ventilation systems. It is designed to sense falling pressure (break on fall), triggering a control or safety shutdown when pressure falls below a set threshold. Ideal for burner gas safety interlocks, blower pressure monitoring, or air/fan differential monitoring.

Features

• Detects positive gas (or air) pressure with reliable diaphragm actuation

• Break-on-fall switch logic (breaks control circuit when pressure drops below setpoint)

• Auto-reset capability (unless configured for manual reset)

• Setting range: 0.4 to 5.0 in. W.C.

• ¼” NPT pressure connection

• Transparent cover over adjustment dial and scale plate

• Adjustment knob protected to prevent tampering

• Durable housing rated for IP54 enclosure

• Silver contacts rated for resistive and inductive loads

• Compatible with natural gas, LPG, or air service

• Optional vent connections and pressure taps available

Specifications

Applications

The Honeywell C6097A3004 switch is commonly used in:

• Gas burner safety systems (monitoring gas inlet pressure)

• Vent or draft pressure detection in furnaces and boilers

• Combustion air blower monitoring and interlock

• Low-pressure differential monitoring for HVAC systems

• Gas valve train interlock systems

It protects downstream equipment by detecting pressure drop and triggering safe shutdown.

Benefits

• High sensitivity for low-pressure detection

• Simple dial adjustment for setpoint tuning

• Auto-reset (or lockout option) improves safety flexibility

• Tamper-resistant design supports compliance

• Robust construction suited for industrial environments

• Universal compatibility with gas, LP, or air systems
