Industry Applications
The Bently Nevada 330191-00-16-90-00 excels in critical machinery monitoring. Typical applications include:
-
Steam and Gas Turbines – Radial and axial shaft vibration measurement for early fault detection.
-
Centrifugal Compressors – Thrust position monitoring to prevent rotor damage.
-
Large Pumps and Motors – Bearing vibration surveillance to extend service life.
Maintenance and Reliability
The cable design of the Bently Nevada 330191-00-16-90-00 features a patented CableLoc method providing 330 N pull strength, reducing the risk of cable detachment. The FluidLoc option prevents oil leakage through the cable interior, ideal for lubricated environments. Routine inspection of the probe tip and cable integrity is recommended every 12 months or per OEM guidelines.
Compatibility and Integration
The Bently Nevada 330191-00-16-90-00 is fully compatible with Bently Nevada extension cables and proximitor assemblies. It meets entity parameters when used with BN extension cables and BN Prox systems. One-meter systems do not require an extension cable. The probe uses a standard 75Ω triaxial connection (FEP or PFA insulated for extended temperature ranges).
Selection Guide and Purchasing Advice
When ordering the Bently Nevada 330191-00-16-90-00, verify total length (9.0 m) and thread specification (3/8-24 UNF). This model is supplied without armor; optional flexible SST armor is available from the manufacturer. For high-temperature applications, specify extended temperature range cable (PFA). PLC Source PRO offers this genuine Bently Nevada 330191-00-16-90-00 in new, factory-sealed packaging with a 12-month warranty.
