Air Compressor Water Pressure Sensor With SS304 Housing M12 Connector
WNK81MA pressure transmitter is a high stable pressure transmitter by using specific ASIC signal conditioning chip and high performance SS316L diaphragm diffused silicon pressure sensor. The internal specific ASIC integrated circuit transforms milivolt signal to standard voltage, current or frequancy signal. It can easily connect with PC interface card, controlling instruments, smart gauges or PLC. It is compact designed, light and stainless steel sealing structure, which enable it capability of working in corrosive environment.
WNK also provides high cost-effective ceramic capacitive pressure sensor. It can be applied to domestic drinking water system, air-conditioning, machinery and refrigeration plant engineering, hydraulic and pneumatic systems, process industries, environmental technology, IIOT and IOT system.
