Field adjustable control set point |
Air sample line connectors will accept 1/8 in, 1/4 in or 3/8 in tubing |
Vertical operating mounting position for diaphragm |
All air switches come in a contractor kit that includes the hardware, replacement hoses and an adjustments tool for easy installation and calibration |
These reliable devices are designed to replace a wide variety of switches found in residential and light commercial applications |
These switches include features such as factory calibrated and factory-fixed set points, NEMA rated housings, manual resets and gold contacts |
Select air pressure sensing switches are practically insensitive to temperature change with an operating range of -40 to 190 deg F |
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 |
Electrical connection is 1/4 in spade |
