- The new Robertshaw® universal air pressure sensing switch and optional probe kit add a new level of flexibility and options to our pressure sensing switch offering
- The available probe adds greater installation and application flexibility by allowing remote installation of the switch by significantly extending the reach of your air sources
- The new universal air pressure sensing switch has field adjustable set points using the included adjustments tool
- The Switch comes in a contractor kit that includes the hardware and replacement hoses
- Like other Robertshaw® air pressure sensing switches, this switch is NEMA rated and is practically insensitive to temperature change with an operating range of -40 to 190 deg F (-40 to 88 deg C)
- The available sensing probe kit works with the universal switch as well as the rest of the Robertshaw® air pressure switch products to provide a form-fit extension from your air sources to the switch, limiting the need to install the switch directly on the air sources
- Conditioned air filters that accumulate particulate matter used to sense the differential pressure or airflow drop across the filter
- Defrost cycle is initiated by sensing differential pressure or airflow drop across the refrigeration coils when they ice
- On gas-fired units, the switch senses draft down from the blower; switch actuation allows ignition start-up or system shutdown upon insufficient draft
- On air-supported structures and enclosures, sensing switches ensures proper inflation or internal pressure; switch actuation controls the blower to maintains pressure
- Exhaust fans and fume hoods employ switches to sense draft down from the exhaust fan, switch actuation signals condition upon fan failures of insufficient draft
- 28 VA pilot duty at 24 VAC/5 A at 24/120/277 VAC
- Silver contacts
The Robertshaw® 2374-510 Air Pressure Sensing Switch has a glass-filled polycarbonate housing containing a sensing diaphragm and an integral snap-acting switch with three male 90 deg quick-connect terminals. The switch can sense positive, negative or differential air pressure. The field adjustable set point range of this switch is 0.10 in WC to 10.0 in WC. Using the switch accessories contained in this kit, the switch can be applied to a wide variety of residential and light commercial HVAC applications.
