About Dwyer Series 43000-0 Capsu-Photohelic Pressure Switch Gage 0-.5" w.c.

Dwyer Series 43000-0 Capsu-Photohelic Pressure Switch Gage 0-.5" w.c.

Model	Description
43000-0	Pressure Switch/Gage, Range 0-.5" w.c.

Lo-Limit and Hi-Limit Control, Aluminum Case

Capsu-Photohelic® Switch/Gages function 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. 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.
