The Bently Nevada 330707-00-20-10-12-00 is a high-precision, non-contacting eddy current sensor designed for industrial machinery protection. This 11 mm proximity probe specifically monitors radial vibration and axial position in critical rotating assets. By utilizing a larger tip diameter than standard 8 mm probes, it provides an extended linear range, which is essential for applications requiring greater clearance or measuring larger displacements.
Technical Characteristics
The 330707 series features a robust metric M14 x 1.5 threaded body, ensuring compatibility with standard metric machine housings. Furthermore, the FluidLoc cable technology prevents process fluids from wicking through the cable, which preserves signal integrity even if the jacket is compromised.

Material and Durability Standards
Because industrial environments are often corrosive, Bently Nevada constructs the probe tip from high-grade Polyphenylene Sulfide (PPS). This material offers exceptional resistance to chemical ingress and thermal degradation. Additionally, the ClickLoc connector system provides a positive-locking mechanism that resists loosening under high-frequency vibration, effectively eliminating the most common cause of signal loss in transducer systems.
