The A/AFS Series differential pressure switches are general purpose
proving switches designed for both HVAC and Energy Management
applications. These pressure switches can be used to sense positive,
negative, or differential air pressures.
The A/AFS-222 has a field adjustable operating range of 0.07" to 12.0"
wc The A/AFS-222 has a field adjustable setpoint range of 0.05" +/- 0.02"
to 12" wc with a field adjustable release range of 0.04" to 11.2" of w.c..
The A/AFS-262 has a field adjustable operating range of 0.07" to 2.0"
wc. It also has a setpoint range of 0.05" +/- 0.02" to 2" wc with a field
adjustable "release range" of 0.04" to 1.9" w.c. The sampling connections
are located on each side of the diaghram.
Both the A/AFS-222 and A/AFS-262 will accept a 0.25" O.D. rigid metallic
tubing via the integral compression ferrule and nut. The enclosure cover
guards against accidental contact with the live switch terminal screws and
the setpoint adjusting screw. Both units also contain a 1/2" conduit
knockout in the cover of the enclosure as well as a diaphragm, calibration
spring, and a snap acting SPDT switch.
