PW220 Electronic Digital Pressureswitch

PW220 Pressureswitch is an intelligent digital pressure measurement and control product that integrates pressure measurement, display, output and control. The all-metal housing design, with a highlighted LED digital display with full electronic structure. The front end adopts the pressure sensor with isolation membrane and oil pressure resistance or ceramic pressure resistance sensor. The output signal is amplified and processed by the amplifier with high precision and low temperature drift, sent to the high precision A / D converter, converted into the digital signal that can be processed by the microprocessor. The signal processed by calculation controls two-way switches to measure and control the pressure of the control system. The product is flexible in use, simple in operation, easy in debugging, safe and reliable. It is widely used in hydropower, tap water, petroleum, chemical, mechanical, hydraulic and other industries to measure, display and control the pressure of fluid medium.
