Dwyer Series 43000 Capsu-Photohelic Pressure Switch-Gage
Lo-Limit and Hi-Limit Control, Aluminum or Brass Case Available
The Dwyer Series 43000 Capsu-Photohelic Switch-Gage functions as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Capsu-Photohelic® switch/gage 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 gage 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.
