Dwyer Instruments A3050 Pressure Gauge - 0 to 50 in H2O

Description

Loss of electrical power or loss of pressure provide "fail safe" protection. 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. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. That is, the equipment will hold in these respective positions once activated and until manually reset. Two phototransistor actuated, DPDT relays are included for low/high limit control. 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. High and Low Latching Circuits Dwyer Photohelic switch/gage can be wired for high-latching, low-latching, or combination high-low latching circuits. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Relay-Transformer Features A plastic housing protects all electronic components.
