Description

Engineered for high-accuracy shaft vibration, axial position, and rotational speed measurements on critical machinery, the Bently Nevada 21501-24-40-10-02 serves as a robust proximity vibration probe within industrial protection systems. This 5mm eddy current sensor transmits high-frequency signals to monitor dynamic motion and static position of target shafts relative to the probe tip, enabling early fault detection in rotating equipment. Designed to operate under severe temperature, pressure, and chemical exposure, it provides essential diagnostic inputs for continuous machinery health monitoring and emergency trip systems.

Features

  • Standard 5mm probe tip diameter optimized for applications with restricted physical clearances.
  • Rugged 3/8-24 UNF threaded casing constructed for extreme industrial environments.
  • Premium miniature male coaxial connector (Option 02) ensuring stable signal connection with minimal attenuation.
  • High-durability insulation and sealing to resist degradation from oils, moisture, and chemical exposure.
  • Direct integration with Bently Nevada Proximitor sensors for linear calibration and reliable data acquisition.

Applications

  • Steam, gas, and hydro turbine shaft vibration monitoring.
  • Centrifugal, axial, and screw compressor displacement tracking.
  • High-speed gearbox shaft vibration and thrust measurements.
  • Large electric motor and generator bearing housing monitoring.
  • Boiler feed pump shaft alignment and runout testing.

Connections and Interfaces

Connector Component Function
Miniature Male Coaxial Pin Transmits high-frequency RF signal from the probe coil to the Proximitor extension cable.
Coaxial Outer Shield Provides system ground return and EMI shielding to prevent signal corruption.

Installation Guidelines

  • Always use a calibrated digital voltmeter to verify output voltage gap settings during mechanical installation.
  • Maintain appropriate clearance between the probe tip and surrounding conductive metals to prevent side-viewing interference.
  • Route probe extension cabling through dedicated, grounded metal conduits to shield against electromagnetic interference.
  • Do not exceed the specified installation torque limits on the locknuts to prevent thread deformation or probe casing failure.

What is the primary application of the Bently Nevada 21501-24-40-10-02 probe?

It is used to measure radial dynamic vibration and axial position of rotating machinery shafts, such as turbines, compressors, and high-speed pumps.

What configuration options do the suffixes -24-40-10-02 represent?

They indicate a 2.4-inch unthreaded length (Option 24), a 4.0-inch overall case length (Option 40), a 1.0-meter total sensor length (Option 10), and a miniature male coaxial connector (Option 02).

Does this probe require a Proximitor sensor to function?

Yes, this 5mm proximity probe must be connected via an extension cable to a matching Proximitor sensor to translate the RF signal into a usable voltage output.
