Bently Nevada 330702-20-30-10-01-05 3300 XL 11mm Proximity Probes

製品紹介

The Bently Nevada 330702-20-30-10-01-05 3300 XL 11mm Proximity Probe is a high-precision non-contact sensor designed for accurate measurement / vibration and shaft position in industrial rotating machinery. As part / the Bently Nevada 3300 XL series, this probe is specifically engineered for applications requiring long measurement ranges and superior linearity, particularly in heavy-duty turbines, generators, compressors, and other large rotating machines.

The 330702-20-30-10-01-05 model provides precise displacement measurements by detecting the distance between the probe tip and the target surface (usually a metallic shaft). It converts this distance into an electrical signal used by monitoring systems such as the Bently Nevada 3500 Series Machinery Protection System. Its 11mm tip ensures a wider linear range than 5mm or 8mm probes, making it ideal for large shaft applications where high amplitude motion and displacement are expected.

Built with durable materials, this probe ensures excellent stability, noise imm台y, and resistance to harsh industrial environments such as high temperature, vibration, and contamination. It is the trusted choice for critical condition monitoring systems across multiple industries.
