PTM350 Hygienic Flat Film Pressure Transmitter
Details
The PTM350 uses a flat membrane to directly sense the pressure signal, uses a diffused silicon pressure core as a sensitive element, and uses standard silicone oil or olive oil as a pressure transmission medium. The measuring end is made of 316L stainless steel, and the special isolation diaphragm is welded .
Features:
1. Pressure interface adopts 316L flat diaphragm structure.
2. Hygienic, anti-scaling.
3, Wide range, can measure absolute pressure, gauge pressure and sealing reference pressure.
4. Good sealing, can work stably for a long time.
5. With heat sink, high temperature medium application performance is excellent.
6. Output signal can be selected, can be customized according to customer requirements.
