Belimo 01APS-50R Pressure Switch
The Belimo 01APS-50R is a field-adjustable differential pressure switch engineered for precision monitoring of air and non-combustible, non-aggressive gases in commercial HVAC systems. This passive duct sensor provides critical feedback for overpressure, vacuum, and differential pressure applications with a tunable setpoint range of 0.08 to 1.20 inches WC (20 to 300 Pa). Designed for high-reliability air flow proving and filter status monitoring, the unit features an integrated SPDT contact rated for 1.0 A at 250 V AC. The assembly includes a 1/2 inch NPT conduit adapter, 2 meters of PVC tubing, and two plastic pitot tubes, ensuring a complete HVAC pressure switch installation kit for the job site. The housing is rated for IP54 / NEMA 3 protection, maintaining performance in challenging mechanical room environments across a wide temperature spectrum from -5°F to 185°F. For accurate switching, veterans know to install the 01APS-50R vertically; horizontal mounting can shift the switching point by approximately 20 Pa.
Key Benefits- Field Adjustable Setpoints: Allows for precise calibration of switching differentials to meet specific system requirements.
- Automatic Reset: Simplifies operation by eliminating the need for manual intervention after pressure stabilization.
- Comprehensive Installation Kit: Includes 1/2 inch NPT adapter, 6-foot PVC hose, and pitot tubes for immediate duct pressure sensor deployment.
- Versatile Application: Ideal for monitoring fan status, filter pressure drops, and frost detection in air handling units.
- Reliable SPDT Output: Provides flexible wiring options for normally open or normally closed logic in energy management systems.
What is the maximum operating pressure for this switch?
The Belimo 01APS-50R is designed to handle a maximum overpressure of 40 inches WC (10 kPa) without damaging the internal sensing diaphragm.
Can this switch be used for liquid flow applications?
No, this model is specifically engineered for air and non-aggressive, non-combustible gases; liquid media will damage the differential pressure sensing element.
How does mounting orientation affect the setpoint?
Calibration is factory-set for vertical mounting. If installed horizontally, the switching point may increase by roughly 0.08 inches WC (20 Pa), so recalibration in the field is necessary.
