Dwyer Instruments A3050 Pressure Gauge, 0 to 50 in H2O

Description

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. 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. That is, the equipment will hold in these respective positions once activated and until manually reset. Relay-Transformer Features A plastic housing protects all electronic components. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Individual set point deadband is one pointer width - less than 1% of full scale. Loss of electrical power or loss of pressure provide "fail safe" protection. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Two phototransistor actuated, DPDT relays are included for low/high limit control. The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases.

Key Features

• 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.
• The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases.
