OverviewGefran KM transmitters are based on a thick-film sensing element deposited on a stainless steel diaphragm. With SMD electronics and a compact all-stainless-steel construction, these transmitters are certified for functional safety and designed for industrial use, notably mobile hydraulics exposed to high shock, vibration, pressure and temperature peaks.
Main features- Designed for mobile hydraulics and industrial applications
- Functional safety options: SIL2, PLd; regulatory options: E1; rail option EN50155 available
- IP69K rating available with automotive connector options
- Compact stainless-steel construction with thick-film sensing element and SMD electronics
Typical applications- Hydraulics: presses, pumps, power packs and fluid power systems
- Mobile machines operating under severe shock and vibration (construction, lifts, agricultural machinery, cranes)
- Industrial processes requiring high EMC immunity and functional safety
NotesDevices incorporate robust sensing and electronics to withstand pressure and temperature peaks typical of mobile and industrial environments. Mechanical and electrical customisation is available on request.
Technical specifications- Pressure ranges: selectable from -1…3 bar up to 0…1000 bar (extensive range codes including negative ranges)
