Hydraulic Pnematic Air Water Pressure Sensor With 4~20mA SS304 Housing
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.
The small pressure transmitter has characteristics of reliable operation, stable performance, easy installation and use, small size, light weight and high cost performance.
It can be widely applied to domestic drinking water system, air-conditioning, machinery and refrigeration plant engineering, hydraulic and pneumatic systems, process industries and environmental technology.
Application fields:
• Pressure measurement of gas, vapor or liquid in various areas;
• Liquid level, volume or mass measurement;
• Integrated in a variety of user-defined solutions;
• Smart water and gas management system, smart fire controlling, automotive electronics controlling, air compressor, HVAC, pump, valve and etc;
