What Is the 146054-08-90-01-00?
When vibration monitoring in rotating machinery demands precision and durability, the Bently Nevada 146054-08-90-01-00 Option: -0 1= provides a reliable solution. This 3300 Ceramic Capped Proximity Probe measures shaft displacement and vibration in critical assets like turbines, compressors, and pumps. Its alumina ceramic tip and AISI 304 stainless steel case withstand harsh environments, while the 9.0 meter (29.5 feet) standard cable offers flexible installation.
Technical Specifications Breakdown
The 146054-08-90-01-00 delivers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. This range covers from 0.25 to 1.78 mm (10 to 70 mils), corresponding to approximately –4 to –16 Vdc. The incremental scale factor (ISF) for a 9-metre system is 7.87 V/mm (200 mV/mil) ±6.5% including interchangeability error, measured over the 60 mil linear range from 0°C to +45°C (+32°F to +113°F). The probe case thread is 3/8-24 UNF with a maximum thread engagement length of 0.563 inches. The probe nominal DC resistance from center conductor to outer conductor is 9.87 ± 0.90 ohms for the 9.0 meter length.
Industry Applications
In steam turbine monitoring, the 146054-08-90-01-00 detects shaft radial vibration and axial position. Its ceramic tip resists wear from high-speed rotation, and the –51°C to +177°C operating temperature range suits turbine environments. For centrifugal compressors, the probe's 1.52 mm linear range captures small displacement changes, helping operators avoid surge conditions. The probe is rated to seal 34 Bar (500 psi) nitrogen, making it suitable for pressurized casings.
Installation Guide
Mount the 146054-08-90-01-00 using the 3/8-24 UNF thread into a drilled and tapped hole. Ensure the probe tip does not contact the rotating shaft during operation. The standard miniature coaxial ClickLoc connector with connector protector simplifies cable attachment. Use the provided 9.0 meter coaxial cable for connection to a compatible Proximitor Sensor. Verify the target material is AISI 4140 steel for accurate performance as specified.
Maintenance & Reliability
Inspect the probe cable and connector periodically for damage. The FEP insulated coaxial cable resists chemicals and high temperatures. The alumina ceramic tip maintains its properties over time, reducing drift. Follow the manufacturer's guidelines for periodic system calibration checks. The 146054-08-90-01-00 carries a 12-month factory warranty from SpareTechPLC, ensuring long-term reliability.
Selection Guide & Purchasing Advice
Before ordering, verify the overall case length (0.8 inches for -08 option) and total length (9.0 meters for -90 option). The -01 connector option includes the miniature coaxial ClickLoc connector with protector. Agency approval option -00 indicates not required. SpareTechPLC supplies this Bently Nevada probe as new and original in factory packing. Contact SpareTechPLC to confirm current lifecycle status and availability.
