Industrial Tank Capacitive Differential Pressure Transmitter with
4~20mA + Hart Explosion Proof
WNK5 series pressure transmitter is the high-performance products
among WNK pressure transmitter series. It transforms physical
signal of pressure, differential pressure and level to standard
signal via collecting cell sensor and digital processing circuit.
WNK5 adopts advanced specified integrated circuit digital
technology to realize best uniformity of accuracy and signal. Each
set of transmitter is ambient temperature compensated, ensured
highest accuracy and lowest drift of transmitters in wide working
temperature range.
WNK55 capacitive differential pressure transmitter supports outputs
of 4~20mA and 4~20mA+ Hart. Its miminum measuring pressure is
10KPa. With good long-term stability and accuracy, WNK50 is widely
applied in oil&gas, cement, petrol, petrol chemical, power,
steel and many industrial fields.
