Description
The Series A3000 Photohelic Switch/Gages function as
versatile, highly repeatable pressure switches combined with a precise pressure
gage employing the time-proven Magnehelic gage design. The photohelic
switch/gage measures and controls positive, negative, or differential pressures
of air and compatible gases. Standard models are rated at 25 psig (1.7 bar),
with options for 35 (2.4) or 80 (5.5 bar) psig. Two phototransistors actuated
by DPDT relays are included for low- and high-limit control. Easy-to-adjust
set-point indicators are controlled by knobs located on the gage face.
