Dwyer Instruments A3050 Pressure Gauge, 0 to 50 in H2O

Description

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. Photohelic Sensing - How It Works In typical applications, these Dwyer switch/gages control between high and low pressure set points. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. That is, the equipment will hold in these respective positions once activated and until manually reset. Series A3000 Photohelic Pressure Switch/Gage, Range 0-50" w.c.3-in-1 Indicating Gage, Lo-limit and Hi-limit Control - Photohelic Switch/Gage function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the. 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. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Applications - Photohelic Switch/Gage In both series of pressure switch/gages, you get the convenience of a visual indication plus high-low limit switching.

Key Features

• Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc.
• 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.
• Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating.
• 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.
• The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases.
• 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.
