Description
The ifm PM1703 and related PM17/PM16 series are flush pressure sensors designed for hygienic and industrial applications requiring dead-space-free media contact. These sensors utilize a ceramic capacitive measuring cell with a flush stainless steel diaphragm, preventing clogging in viscous or particulate media. Models such as PM1703 (-1…25 bar), PM1714 (-1…16 bar), PM1708 (-0.0125…0.25 bar), PM1707, PM1689 (-0.005…0.1 bar), PM1608, PM1704 (-1…10 bar), and PM1604 cover a wide range of pressure measurements from micro-pressure to medium-high pressure. All feature 4–20 mA analog output with IO-Link communication, G1 process connection, and IP67/IP68/IP69K protection for washdown environments.
Key Features
- Flush Diaphragm: Dead-space-free design prevents blockages in sticky or fibrous media.
- Measuring Ranges: From -1…25 bar (PM1703) down to -0.005…0.1 bar (PM1689) for micro-pressure.
- Output: 4–20 mA analog + IO-Link (smart configuration via ifm moneo / PLC).
- Process Connection: G1 thread (aseptoflex vario on PM17xx; sealing cone on PM16xx).
- Protection Rating: IP67 / IP68 / IP69K — suitable for CIP/SIP cleaning.
- Wetted Materials: Stainless steel 316L + ceramic Al₂O₃ diaphragm.
- Country of Origin: Germany
