Key parameters
Measuring range
Linear range 27.9 mm (1100 mils) — longest in Bently eddy-current line; recommended gap approx. 1.3–29.2 mm yielding approx. −1.5 to −12.5 Vdc
Accuracy
Average Scale Factor (ASF) 394 mV/mm (10 mV/mil) nominal; relative humidity <3% ASF change per IEC 68-2-66 test
Output
Proximitor voltage output identical to 7200 / 50 mm DE Integral (0.394 V/mm); SpringLoc field wiring
Supply
−17.5 to −26 Vdc without barriers at 12 mA max; −23 to −26 Vdc with barriers
Approvals
CE
Mounting
Thread options including 1/2-20 and M14×1.5; sliding-bracket accessories; replaces 7200 50 mm systems
Fits very large-gap eddy-current proximity where you need a Bently Nevada 3300 XL 50 mm system. Probe plus extension and Proximitor with 27.9 mm (1100 mils) linear range—the longest in the Bently eddy-current line—average scale factor 394 mV/mm (10 mV/mil) nominal, and −17.5 to −26 Vdc supply without barriers.
Key advantages
- Linear range — 27.9 mm (1100 mils)
- ASF — 394 mV/mm (10 mV/mil) nominal
- Compatibility — Output matches 7200 / 50 mm DE Integral class
- Supply — −17.5 to −26 Vdc (no barriers)
- Wiring — SpringLoc
Typical applications
- Very large-gap proximity.
- Differential expansion long stroke.
- Legacy 50 mm replacements.
