Features:

  • Chemical‑Resistant Ceramic Tip for Harsh Media
  • Full 3300 XL System Interchangeability
  • Hermetic Pressure Sealing for Rotating Machinery
Unlike standard polymer‑tipped probes, the Bently Nevada 146054-08-05-02-05 uses an alumina ceramic cap specifically validated against anhydrous ammonia, hydrogen sulfide, and acidic process gases – preventing tip degradation and extending service life in chemical and fertilizer plants.

The Bently Nevada 146054-08-05-02-05 is electrically and mechanically compatible with the 3300 XL Proximitor Sensor and extension cable family, supporting component‑level replacement without bench recalibration. This directly reduces maintenance turnaround time.

The front‑end ceramic‑to‑metal interface is helium leak‑tested, enabling the Bently Nevada 146054-08-05-02-05 to reliably operate at static pressures up to 34 Bar (500 psi). It is suitable for compressor casings, turbine bearing housings, and high‑pressure pump monitoring.

The 146054-08-05-02-05 Bently Nevada 3300 Ceramic Capped Proximity Probes may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer Bently Nevada
  • Model 146054-08-05-02-05
  • Condition New Original ready stock
  • Product Family 146054-12-10-02-05,146054-12-10-02-00,146054-12-10-01-052
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Full temperature range requires correct mounting – The -51°C to +177°C rating applies only when the probe body is properly threaded into a metal housing. Free‑air or conduit‑only mounting degrades rating.
  • Pressure seal is directional – The 34 Bar (500 psi) rating is for static pressure acting on the ceramic tip. Reverse pressure or rapid decompression cycles are not fully characterized in standard documentation.
  • Not rated for subsea or continuous liquid immersion – While corrosion‑resistant, the Bently Nevada 146054-08-05-02-05 is not a submersible sensor; it is intended for sealed casings and pressurized gas environments.
  • EMI immunity supports installation without metal conduit – RFI/EMI performance allows use in fiberglass or non‑metallic junction boxes, but interconnecting cable shielding must be properly grounded per installation drawing.
  • Intrinsic safety installation required – For Zone 0/1 use, the Bently Nevada 146054-08-05-02-05 must be installed with approved zener barriers (drawing 141092) or galvanic isolators, not as a simple standalone device.
  • Rear of probe is NOT sealed – The probe prevents ingress only at the ceramic front end. The connector and cable area must be routed away from water, ammonia, or H₂S; otherwise, process fluid can enter the rear and cause failure.
  • Thread engagement limit enforced – Maximum thread engagement is 0.563 inches (3/8‑24 thread). Exceeding this limit may bind or damage the probe case and voids warranty.
  • No field repair or modification allowed – Any disassembly, cable splice, or connector change compromises hazardous area certification and manufacturer safety compliance.
  • Compressor surge & vibration monitoring in high‑pressure gas and refrigerant services
  • Turbine shaft eccentricity during startup and coast‑down
  • Thrust bearing position in axial compressors and steam turbines
  • Chemical process pumps exposed to acidic or caustic media
Description
The Bently Nevada 146054-08-05-02-05 is purpose‑built for environments where standard proximity probes fail prematurely. Its alumina ceramic (Al₂O₃) tip and AISI 304 stainless steel case provide robust protection against corrosive gases, anhydrous ammonia, and high‑moisture conditions, ensuring consistent measurement integrity in chemical processing, power generation, and oil & gas facilities.

As part of the 3300 XL system architecture, the Bently Nevada 146054-08-05-02-05 maintains full compatibility with 3300 Proximitor Sensors and extension cables. It delivers a linear measurement range of 1.52 mm (60 mils) and an incremental scale factor of 7.87 V/mm, enabling precise shaft vibration, thrust position, and eccentricity monitoring without field recalibration when using standard target materials.

The Bently Nevada 146054-08-05-02-05 is rated for extreme service conditions, including operating temperatures from -51°C to +177°C and static pressures up to 34 Bar (500 psi). It carries multiple hazardous area approvals (CSA, ATEX, IECEx), making it suitable for global installation in Zone 0/1 and Class I, Division 1 environments.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What rotating machinery applications is the Bently Nevada 146054-08-05-02-05 intended for?
It is designed for non‑contact vibration, thrust position, shaft eccentricity, and differential expansion monitoring on gas/steam turbines, centrifugal compressors, blowers, pumps, and electric motors in petrochemical and power generation plants.
Can the Bently Nevada 146054-08-05-02-05 be used with standard 3300 XL extension cables?
Yes. It is fully compatible with 3300 XL series extension cables, provided the total electrical length (probe + cable) does not exceed the Proximitor Sensor’s specified loop length.
Is the Bently Nevada 146054-08-05-02-05 suitable for anhydrous ammonia environments?
Yes. The ceramic cap is specifically rated for NH₃ service. However, the rear of the probe (connector and cable end) is not sealed; it must not be exposed to water, NH₃, NH₄OH, or hydrogen sulfide. This is a critical installation constraint.
How does the linear range differ from standard 3300 XL probes?
The linear range (0.25–1.78 mm / 10–70 mils) is shifted slightly. If configured using standard 3300 XL monitor settings, the probe tip may contact the shaft before reaching the lower OK limit. Monitor configuration adjustments may be required.
