The Dwyer Instruments A3015-RMR Photohelic Pressure Switch/Gauge is a versatile and precise instrument designed for measuring and monitoring pressure in various applications. This pressure switch/gauge comes with an innovative photoelectric sensing technology that offers several advantages over traditional mechanical pressure switches.
The A3015-RMR features a clear, easy-to-read 1-1/2-inch (38.1 mm) dial gauge with a red pointer against a white background, providing excellent visibility and accuracy. The dial face is graduated in 5 psi (0.34 bar) increments from 0 to 3000 psi (206.8 bar), making it suitable for high-pressure applications.
This pressure switch/gauge operates on a photoelectric principle, meaning it uses a light beam to detect pressure. The sensing element consists of a diaphragm and a light source. When the pressure acting on the diaphragm reaches the set point, the diaphragm deflects, breaking the light beam. This interruption of the beam triggers the switch output, which can be configured to activate an alarm, turn on a light, or perform any other desired function.
The A3015-RMR is designed for rugged use in industrial environments, with a heavy-duty, cast aluminum housing and a borosilicate glass dial window. It is also equipped with an adjustable zero feature, allowing users to set the pressure at which the switch activates to zero. This feature ensures accurate and reliable pressure measurement and switching.
The pressure switch/gauge can be easily installed and configured using the provided mounting bracket and wiring terminals. It also comes with a 10-foot (3.05 m) cable and a 1/8 NPT (6 mm) pressure connection. The switch has a voltage range of 100-240 VAC and a switch output of 5 mA or 24 VDC.
Overall, the Dwyer Instruments A3015-RMR Photohelic Pressure Switch/Gauge is an excellent choice for users who require accurate, reliable, and easy-to-use pressure monitoring and switching solutions in industrial applications. Its innovative photoelectric sensing technology, rugged design, and versatile output options make it a valuable addition to any industrial control system.
