Dwyer Series 43000 Capsu-Photohelic

Lo-Limit and Hi-Limit Control, Aluminum or Brass Case Available
 

Capsu-Photohelic® Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® design. The Capsu-Photohelic® 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 setpoint indicators are controlled by knobs located on the gage face. Individual setpoint deadband is one pointer width — less than 1% of full scale. Setpoints can be interlocked to provide variable deadband — ideal for control of pumps, etc.

 
Set points are instantly adjusted with front knobs.
