Viscous fluids pressure sensor and transmitter adopts AP27 series flush diaphragm sanitary pressure transmitter. The pressure transmitter is specially designed for viscous, pasty, adhesive, crystallized, particle-laden and contaminated media that can clog pressure channels in traditional process connections measurement in.
Viscous fluids pressure transmitter is a high-precision, high-stability pressure sensor designed and produced using precision compensation technology. The measuring range features a flat-embedded diaphragm, robust design and state-of-the-art workmanship.
* No cavity corrugated flat membrane
* High reliability
* Wide measurement range
* Optional live display
