Dwyer Photohelic Pressure Switch Gauge
$1,259.00Original price was: $1,259.00.$1,059.00Current price is: $1,059.00.
The Dwyer Photohelic Pressure Switch Gauge, Series A300, measures and controls positive, negative or differential pressures of air and compatible gases.
The Series A3000 Photohelic® Switch/Gauge functions as a versatile, highly repeatable pressure switch combined with a precise pressure gauge that employs the time-proven Magnehelic® gauge design.
Precision Instruments for Accurate Air Flow and Pressure Measurements
A3301: Pressure switch/gauge, range .5-0-.5″ w.c.
Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig.
Two phototransistor actuated, DPDT relays are included for low/high limit control.
Easy to adjust set point indicators are controlled by knobs located on the gauge face.
The individual set point deadband is one pointer width – less than 1% of full scale.
Set points can be interlocked to provide variable deadband – ideal for control of fans, dampers, etc.
The gauge reading is continuous and unaffected by switch operation, even during loss of electrical power.
Ships warehouse direct in 3-5 days.
