Product Details
Industrial IP67 Explosion Proof Smart Differential Pressure Level
Transmitter 4~20mA, Hart
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.
