Photohelic® switch/gages series AT3-A3000 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. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure also available. Two phototransistor actuated, DPDT relays are included for low/high limit control. easy to adjust setpoint indicators are controlled by knobs located on the gage face (accessible opening case after de-enegizing instrument).
Individual setpoint deadband is one pointer width – less than 1% of full scale. Setpoints can be interlocked to provide variable deadband – ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power.
Several ranges available (see standard ranges table).
