SS304 4~20mA 0.2-2.9V SPI, I2C Water Pipe Water Pressure Sensor
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.
WNK81MA is solution for below applications:
• 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;
• Specific high performance ASIC conditioning circuit;
• Diffused silicon pressure sensor;
• Stainless steel, aluminium and copper housing;
• 0.5…4.5V, 4…20mA, 1...5V and 0...10V analog output or I2C and SPI digital output;
• Fast respond, no hysteresis ;
• Various process thread or other customization port acceptable;
• Accurate, stable and reliable

Power Supply

 Supply voltage 5V 24VDCregulated power supply,
 Supply voltage effect

 5V supply voltage effect: min.3V/max.5.5V
●For 0.5…4.5V output sensor, voltage has no effect for linearity and temperature compensation, voltage is proportional to LRV and FRV.
●For I2C and SPI digital output sensor, voltage has no effect for linearity, LRV, URV and compensation temperature.
 24V supply power effect: min.9V/max30V
●For 4…20mA current output sensor, voltage has no effect for linearity, LRV, URV and compensation temperature.
