Technical Specifications

Functional Description

The probe uses eddy‑current technology to measure shaft displacement and vibration. Its compact design allows installation in tight spaces, while the FEP cable ensures durability and chemical resistance. The probe delivers a linear signal compatible with Bently Nevada monitoring systems, enabling accurate diagnostics of machine health.

Key Applications

• Compressors: Centrifugal air, refrigeration, and process gas compressors

• Restricted Clearances: Areas where standard probes cannot be installed

• Small Targets: Radial vibration measurement on shafts under 51 mm (2 in)

Frequently Asked Questions

• What makes the NSv probe different from standard probes?  It is designed for narrow side‑view (NSv) applications, fitting into restricted clearances where larger probes cannot be installed.

• Can this probe be used on small shafts?  Yes, it is optimized for shafts under 51 mm (2 in).

• What is the advantage of the FEP cable?  It provides chemical resistance and durability in harsh industrial environments.
