Product Description
   WNK4S pressure transmitter is the cost-effective model of pressure transmitters provided by Anhui WNK Electronic Engineering Co., Ltd. It transforms the physical signal of pressure, differential pressure and level etc into standard signal, by collecting cell sensor and digital processing circuit.
  WNK4S series has the precision and signal uniformity by applying advanced specified integrated circuit digital technology. Each set of transmitter is ambient temperature compensated in our factory, to ensure max precision and mini drift in wide working temperature range.
   Accurate, Stable, Reliable.
