Dwyer Instruments A3050 Pressure Gauge - 0 to 50 in H2O

Description

Easy to adjust set point indicators are controlled by knobs located on the gage face. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. High and Low Latching Circuits Dwyer Photohelic switch/gage can be wired for high-latching, low-latching, or combination high-low latching circuits. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. - Relay-Transformer Features A plastic housing protects all electronic components. Photohelic Sensing - How It Works In typical applications, these Dwyer switch/gages control between high and low pressure set points. For both OEM and in-plant applications, the Photohelic switch/gage is used to control pressures in air conditioning systems, clean rooms, fluidic and pneumatic control systems, materials handling equipment, alarm or control fume exhaust systems, control. Loss of electrical power or loss of pressure provide "fail safe" protection. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards. - Applications - Photohelic Switch/Gage In both series of pressure switch/gages, you get the convenience of a. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards.

Key Features

• Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating.
• Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. - Relay-Transformer Features A plastic housing protects all electronic components.
• Loss of electrical power or loss of pressure provide "fail safe" protection. - High and Low Latching Circuits Dwyer Photohelic switch/gage can be wired for high-latching, low-latching, or combination high-low latching circuits.
• Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc.
• The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases.
