Dwyer 43204 43000 Pressure Switch Gage

Dwyer, 43204, Pressure switch/gage 0 to 4 psid

Lo-Limit and Hi-Limit Control, Aluminum

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 employ an encapsulated sensing element for use with both liquids and gases at pressuresto 500 psig (34 bar). 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.

• Single Contact, right set point, for actuation on increasing or decreasing pressure.
• Power Supply, 24 VAC or 220 VAC powered relay pack.
• Remote-Mounted Relay, relay pack may be mounted remotely from gage. Specify cable length required.
• Tamper-proof Knobs, low temperature option, special scales, voltages and other features and modifications are available.
• Special Housings, available include Weatherproof (NEMA 4) and Explosionproof (NEMA 7 CD, 9 EFG; NEC Class I, DIV. 1 & 2, Groups C, D, Class II, Div. 1 & 2, Groups E, F, G, Class III. Contact Customer Service for detailed dimension drawings.
