HONEYWELL C6045D1050 Gas & Air Differential Pressure Switch

Product Dimensions：

The Honeywell C6045D1050 is a highly reliable, international-grade Gas and Air Pressure Switch designed for industrial combustion systems. It is engineered to monitor positive pressure or differential pressure, acting as an essential safety interlock device in burner and boiler operations.

Product Detailed Description

The C6045D1050 features a sensitive internal diaphragm linked to a Single Pole Double Throw (SPDT) snap-acting microswitch. It continuously senses the line pressure against a user-adjustable mechanical setpoint. When the monitored gas or air pressure rises above or falls below the desired setting, the microswitch toggles, immediately changing state to signal the control system (PLC or burner management unit) to shut down or trigger an alarm.

Technical Parameters

Product Advantages

• Dual-Purpose Versatility: Can easily be piped to function as a positive pressure monitor or a differential pressure switch across filters or fans.
• External Visibility: The setpoint numerical scale and the actual mechanical switch position indicators are visible from the outside via a clear window, easing routine visual audits.
• Robust Microswitch: Built around a rugged Honeywell snap-acting microswitch that handles heavy inductive or resistive motor control loads directly up to 10 A.
• Integrated Safety Features: Includes a leakage limiting orifice inside the vent assembly to restrict gas flow if the internal sensing diaphragm is ever ruptured.

Important Considerations & Precautions

• Mounting Restrictions: The standard scale configuration is calibrated assuming horizontal or near-vertical installation. If mounted at angles greater than 20° from horizontal, gravity may shift the internal diaphragm weight and alter the actual trip point.
• Vent Piping (Combustible Gases): When managing combustible gases rather than simple air, the 1/8″ low-pressure/vent tapping must be safely piped away directly into the combustion chamber or a secure outdoor ventilation stack.
• Accuracy Verification: While a numerical scale is printed on the unit under the cover, always use an inline manometer/pressure gauge during commissioning to fine-tune and confirm precise cut-off pressure points.
• Electrical Safety: Ensure power is fully isolated before removing the plastic top cover to adjust the setpoint screw, as 230V mains terminals are exposed inside the housing.

Product Applications

The C6045D1050 is predominantly utilized within commercial heating and industrial process plant environments:

• Gas Train Monitoring: Serving as a low-pressure or high-pressure gas cutoff safety switch on gas burner manifolds.
• Combustion Air Proofing: Acting as a differential switch across main industrial air blowers to verify that proper airflow is established before gas valves are allowed to ignite.
• Exhaust & Ventilation Interlocks: Ensuring flue exhaust systems are drawing correctly on large boilers, kilns, or commercial ovens.
• Filter Monitoring: Measuring differential pressure drops across large air intake filters to flag blockage alarms for facilities maintenance teams.
