Product Information:

The 21501-00-16-05-02 is a standard 8mm eddy current displacement sensor probe from the 7200 series manufactured by Bently Nevada. As a classic front-end hardware component in early industrial rotating machinery protection systems, it utilizes the non-contact eddy current principle to achieve long-term real-time monitoring of shaft vibration, axial displacement, and rotational speed in equipment such as large turbines, compressors, and centrifugal pumps by measuring the dynamic, minute gap between the probe end face and the rotating shaft online.

Depending on the specific parameter selection code, the 21501-00-16-05-02 can be specially configured to meet the installation requirements of certain housing structures. In this configuration, 21501 represents the 7200 series 8mm threaded front mounting base model (using 3/8-24 UNF imperial thread); option 00 indicates that the probe is fully threaded (0mm non-threaded length); option 16 indicates that its total housing thread length is 1.6 inches. Option 05 corresponds to a standard coaxial cable length of 0.5 meters (approximately 1.6 feet); Option 02 indicates a standard miniature male ClickLoc coaxial connector at the end.

The overall configuration of 21501-00-16-05-02 is not explosion-proof certified and is suitable for general safe production areas. In actual industrial operation and spare parts maintenance, although this probe belongs to an earlier series from Bently Nevada, it still plays a crucial protective role in many older, in-service equipment.

Features:

  • 5 mm Standard Mount Probe
  • 7200 Proximity Transducer Systems 5 mm and 8 mm
  • Noncontacting, gap-to-voltage transducer systems
An improved 8 mm version of the 7200 System is now standard which includes Bently Nevada's Cable LoC™ feature. This new technique of securing the coaxial cable to the probe tip provides the strongest junction yet offered by Bently Nevada and increases the durability of the probe during installation and usage. Two new cable length options are now available on 8 mm probes. They are 5 metres and 9 metres of integral cable. Since the entire lead-length is built into the probe, an extension cable is not used with these length options.

Nine probe configurations are available to accommodate English and metric thread requirements. The 5 mm probes are constructed of fiberglass. The 8 mm probes are constructed of polyphenylene sulfide, (PPS), a high performance plastic capable of withstanding unusually harsh, wet and/or chemical environments. Both transducers are suitable for use in a confined space and offer 80 mils (2 mm) of linear range with a scale factor of 200 mV/mil (8 V/mm).

The 21501-00-16-05-02 Bently Nevada 5 mm Standard Mount Probe may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 7200 5 and 8 mm Systems have a frequency response of 0 Hz (DC) to 10 kHz and can be used to make the following types of measurements:
• Radial vibration for indicating bearing condition and such machine
malfunctions as rotor imbalance and misalignment.
• Axial thrust position for determining thrust bearing wear or
potential bearing failure.
• Shaft average radial position, for determining attitude angle, an indicator of rotor stability.
• Vibration amplitude and phase angle for plotting diagnostic information in Polar and Bode formats.
• Eccentricity to measure the amount of rotor bow.

Technical notes

The Bentley Nevada 21501-00-16-05-02 is a 7200 series 5mm axis vibration and displacement sensor with a wideband response from 0 Hz to 10 kHz and a high-precision sensitivity of 200 mV/mil. Its stainless steel housing and built-in armor protection make it particularly suitable for radial vibration or axial displacement monitoring in high-precision industrial environments.
