| The photohelic
switch/gauges function in the same manner, as versatile, precise
pressure switches combined with a pressure gauge utilizing the time
proven magnehelic design. Available with 1 or 2 LED/phototransistor
actuated relays. Gauge reading is unaffected by switch operation. Easy
to adjust set points with knob controls. Apply pressure and switch set
points are fully visible. Deadband is 1 pointer width—less than 1%
full scale. DPDT relays can easily be interlocked to provide variable
deadband control. For positive, negative or differential pressures as
low as 0.25" water column to 0 to 300 psi full scale; set points as
low as .01 w.c. on .25" scale unit. |
