I2C Water Pressure Sensor 3.3V Power Supply And High Accuracy 0.5%FS
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.
We also have WNK80MA ceramic capacitive pressure sensor. WNK80MA and WNK81MA both have outputs of 4~20mA, SPI, I2C, 0.2-2.9v, 0.5-4.5v, 0-5v and other outputs. With small size, stainless steel housing and high accuracy, WNK80MA and WNK81MA are widely applied to air compressor, HVAC, water and gas management system, smart city, and etc.

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.
