Product Short Description
330106-A05-B30-C10-D02-E00 is a high-precision industrial eddy-current proximity probe manufactured by Bently Nevada (Baker Hughes). It belongs to the flagship 3300 XL product family. This product adopts non-contact eddy current sensing principle, forms a complete measurement system with original 3300 XL proximitors and extension cables. It converts gap distance between probe tip and conductive metal rotor targets into proportional DC voltage signals. It supports simultaneous static shaft radial/axial position monitoring and dynamic radial vibration displacement measurement.
