AP27 series flush diaphragm sanitary 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, specially designed for viscous, pasty, adhesive, crystallized, particle-laden and contaminated media that can clog pressure channels in traditional process connections measurement in.

The flush diaphragm sanitary pressure transmitter design has been optimized through years of field experience, and the process connection of the flush diaphragm is adopted, which can give full play to the cleaning ability of the wetted diaphragm during the process. This ensures trouble-free and easy maintenance even for pressure measurement in critical applications with frequent media changes.
