Dwyer Instruments - Series A3000: A3003 Photohelic Pressure Switch/Gage • Air Conditioner Systems • Clean Rooms • Fume Exhaust Systems Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases.

The A25 Series Warm Air Control with Manual Reset is designed to shut down fans, burners, dampers, etc., when the temperature of the sensed air becomes greater than the controller’s setpoint. When the sensed temperature increases to the controller’s setpoint, the A25’s switch will open. Manual reset is required to reclose the electrical circuit.
