S-11 – Flush Pressure Transmitter
The WIKA S-11 Flush Pressure Transmitter is a robust electronic pressure sensor engineered specifically to measure the pressure of viscous, paste-like, adhesive, crystallising, or particle-laden media. Its specialized flush diaphragm design prevents the clogging and buildup that typical recess-diaphragm transmitters experience in harsh process channels.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The WIKA S-11 is a high-performance electronic pressure transmitter designed specifically for demanding applications involving thick, sticky, or contaminated fluids. Unlike standard sensors that use a recessed cavity where particles can settle, the S-11 features a flat, front-flush diaphragm. This seamless design eliminates dead space, preventing the media from clogging the sensor, hardening inside the port, or contaminating the process line.
