    Capsu-Photohelic Switch/Gauges function as versatile, highly repeatable pressure switches combined with a precise pressure gauge employing the time-proven Magnehelic gauge design. The Capsu-Photohelic switch/gauge employs an encapsulated sensing element for use with both liquids and gases at pressures to 500 psig (34 bar). Optional cast brass case is available for water or water based liquids. 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. 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 pumps, etc.
