4-20MA I2C Small Size Diffused Silicon Pressure Sensor For Air
Compressor
Product Description
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.

●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. |
