Description

Series 43000 Capsu-Photohelic® Pressure Switch/Gage, Lo-Limit and Hi-Limit Control, Aluminum or Brass Case Available

 

DWYER Series 43000 Capsu-Photohelic Pressure Switch/Gage function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The DWYER Series 43000 Capsu-Photohelic Pressure 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 phototransistors 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.

Features

• Gage capsule permits high-pressure usage with small differentials
• Zero and range adjustments outside of gage means no disassembly in normal service
• Time-proven, simple, frictionless movement that permits full scale readings as low as 0.5 in w.c.
• Photo-electronic relays provide fast-acting switching with variable deadband control for chatter-free operation
