Cleveland Controls RFS-4001-037 Pressure Switch
The Cleveland Controls RFS-4001-037 is a high-performance adjustable pressure switch designed for sensing differential air pressure in HVAC systems and industrial process applications. This field-proven air pressure sensing switch features a versatile setpoint range, allowing for precise differential pressure control from 0.15" w.c. ± .02" up to 2.0" w.c. Engineered with an SPDT contact configuration, the unit triggers contact status changes upon increasing pressure, making it an essential component for monitoring blower motor proof of airflow and filter status in commercial air handling units. The RFS-4001-037 supports a maximum pressure rating of 1/2 PSI and is rated for electrical loads up to 277Vac. Its robust design ensures reliable performance in demanding environments, whether utilized for low-limit safety cut-off or high-limit pressure monitoring. For contractors performing system maintenance, this switch provides the HVAC pressure switch calibration flexibility needed to match specific manufacturer requirements without carrying multiple fixed-setpoint units.
- Wide Operating Range: Adjustable setpoint from 0.15" w.c. to 2.0" w.c. handles various static pressure requirements.
- Universal Application: Compatible with positive, negative, or differential pressure sensing applications.
- Durable Construction: Rated for 1/2 PSI max pressure and high-voltage 277Vac electrical circuits.
- Precision Sensitivity: Maintains tight tolerances of ± .02" w.c. at the lower end of the adjustment scale.
- Standardized Integration: Features standard terminals and a compact footprint for easy field replacement.
The setpoint is adjusted by rotating the calibration screw. Rotating the screw clockwise increases the pressure required to actuate the switch, while counter-clockwise decreases it. Always use a calibrated manometer to verify the trip point during installation.
Can this switch be used for both vacuum and positive pressure?Yes, the RFS-4001-037 is designed to sense positive, negative (vacuum), or differential air pressure by utilizing different port configurations on the housing.
What is the maximum electrical load for this pressure switch?This unit is rated for pilot duty and general-purpose applications up to 277Vac, making it compatible with most commercial control circuits and line-voltage safety loops.
