This pressure switch with pressure transducer can be used to measure and control pressure for various industries, including Petroleum and chemical industry, Electric power, water & waste water treatment, Truck, Pumps and other automatic control industries.
WP401B pressure switch adopt advanced imported advanced sensor component, which is combined with the solid state integrated technological and isolate diaphragm technology. The pressure transmitter is designed to work well under various conditions. The temperature compensation resistance makes on the ceramic base, which is the excellent technology of the pressure transmitters. It has standard output signals 4-20mA and switch function (PNP, NPN). This pressure transducer has strong anti-jamming and suits for long distance transmission application.
