Dwyer Instruments A3000-10KPA

Photohelic Pressure Switch/Gage Range 0-10 kPa.

Order #: A3000-10KPA

Mfg #: A3000-10KPA

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. 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 to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. 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 fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25" (0-6 mm) w.c. up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar).
