    Description

    The Photohelic A3002 Switch/Gauge is a highly repeatable pressure switch combined with a precise pressure gauge that measures and controls positive, negative or differential pressures of air and compatible gases.  Two integral phototransistor actuated DPDT relays provide low and high limit control.  Low and high setpoints are adjustable with knobs on the gauge face.  Gauge reading is continuous and is unaffected by the switch operation or loss of power.  A zero adjustment screw on gauge face adjusts zero pressure reading.  The 0 to 2" W.C. range is ideal for monitoring and alarming the loading of air filters on air handling units.
    Electronics are designed to operate on 50/60 Hz, 120 volt current with 10% over or under voltage.   Gauge cover is clear polycarbonate plastic.  Plastic enclosure protects electronic components and electrical connections.  Switch set pointers show switch settings at all times. Accuracy is +/-2% of full scale at 70 degrees.  Repeatability is +/-1% F.S.  Pressure connections are 1/8" female NPT. Gauge face measures 4 inches in diameter, 5 1/4" overall with mounting ring.  Hole cutout is 4-47/64".  Housing is 3-7/8" square. Overall length is 7-3/4".   Agency approvals include UL, CSA and CE.  Includes free shipping.
