WNK Absolute Pressure Sensor With 4-20mA Output
Based on technology of A10 series, WNK80mA is low cost and high performance oil filled pressure transmitter. It is with completely welded stainless housing and installed ASIC to realize digits amplification, linearity and temperature compensation. Circuit design is highly integrated meeting lastest CE on electromagnetic interference standard.
The WNK80mA transmitter is in small size with various optional thread connection and wiring method; output standard 4~20mA or 0.5-4.5V, 0-5V etc industrial signal. We could also produce varied special structure and output products as per customers requirements.
