Dwyer 43000-500PA

<p><strong>Dwyer, 43000-500PA, Series 43000 Capsu-Photohelic? Pressure Switch Gage, Range 0-500 Pa </strong> </p> <p>Lo-Limit and Hi-Limit Control, Aluminum Case </p> <p><strong>Capsu-Photohelic? Switch/Gage </strong> 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. </p> <p>? </p>
