PM1608 Flush Pressure Transmitter -0.0125…0.25 bar 4‑20mA IO‑Link | IFM

The Original New IFM PM1608 Flush Pressure Transmitter is a hygienic, flush‑mount pressure sensor designed for the food and beverage industry. Featuring a ceramic‑capacitive measuring cell in a fully welded stainless steel housing with G1 external thread sealing cone process connection, it enables dead‑space‑free installation to prevent product buildup and bacterial growth. Resistant to high‑pressure cleaning with aggressive cleaning agents and high temperatures, the transmitter provides a scalable 4‑20 mA analog output with IO‑Link communication.

Core Engineering Highlights:
