Overview Manuals Principle

Features:

  • 5 mm and 8 mm Standard Mount Probe
  • 7200 Proximity Transducer Systems 5 mm and 8 mm
  • Noncontacting, gap-to-voltage transducer systems
The 7200 5 mm and 8 mm Proximity Transducer Systems are noncontacting, gap-to-voltage transducer systems that measure static as well as dynamic distances between the probe tip and the observed target. The general application is any requirement for an accurate, noncontacting displacement measurement. However, the most common use is for shaft position and vibration measurements on rotating and reciprocating machinery.

They are designed for use with virtually any machine type including gas and steam turbines, compressors, pumps, centrifuges, electric motors and generators. The systems offer 80 mils (2 mm) of linear measuring range and are compatible with API 670 requirements.

The 21505-00-40-10-02 Bently Nevada 8 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).
Bently Nevada 21505-00-40-10-02 8 mm Standard Mount Probe Manuals(Datasheets), Link 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.
The 5 mm and 8 mm systems use the same type of Proximitor. Both 5 and 9 metre Proximitors are available. A threeconductor, shielded cable provides the signal output and power source input between 7200 Proximitors and Bently Nevada monitors. Proximitors can be located up to 1,000 feet from standard Bently Nevada monitors without degradation of performance

Ask our team:

  • What functional role does 21505-00-40-10-02 perform within a 7200 Proximity Transducer System architecture?
    The 21505-00-40-10-02 serves as a precision eddy-current proximity probe engineered for non-contact measurement of shaft displacement and vibration in rotating machinery. Within the 7200 system topology, 21505-00-40-10-02 operates as the primary sensing element, converting mechanical displacement into a proportional electrical signal for downstream signal conditioning and dynamic analysis.
  • How does 21505-00-40-10-02 achieve high-fidelity radial vibration measurement under industrial operating conditions?
    The 21505-00-40-10-02 utilizes eddy-current transduction principles, wherein an oscillating RF signal induces eddy currents in the conductive target. Variations in the probe-to-target gap modulate the oscillator amplitude, thereby producing a linearized voltage output proportional to displacement. The electromagnetic field geometry and coil design in 21505-00-40-10-02 ensure exceptional linearity, thermal stability, and immunity to contaminants such as oil mist or process vapors.
  • What mechanical and dimensional specifications characterize 21505-00-40-10-02?
    The 21505-00-40-10-02 is configured according to the ordering code parameters embedded within its part number, typically defining probe tip diameter, thread configuration, overall case length, cable length, and connector type. These mechanical attributes ensure compatibility with turbine, compressor, and motor bearing housings requiring tight installation tolerances and repeatable positioning accuracy.
  • Why is the linear measurement range of 21505-00-40-10-02 critical for machinery protection applications?
    The 21505-00-40-10-02 is designed to provide a calibrated linear range suitable for accurate shaft position and dynamic vibration monitoring. Maintaining operation within this specified linear span ensures minimal scale factor deviation and phase distortion, which is essential for reliable machinery diagnostics, orbit analysis, and condition-based maintenance strategies.
  • How does 21505-00-40-10-02 interface with extension cables and proximitor sensors within the 7200 system?
    The 21505-00-40-10-02 forms one integral component of a matched transducer system, operating in conjunction with a calibrated extension cable and proximitor (signal conditioner). The total electrical length—including the probe cable—must match system specifications to preserve calibration constants, sensitivity (mV/mil or mV/µm), and frequency response bandwidth.
  • How does 21505-00-40-10-02 ensure signal stability across varying target materials?
    The 21505-00-40-10-02 is calibrated for specific conductive materials (commonly steel-based alloys). Variations in material conductivity and magnetic permeability influence the electromagnetic field interaction; therefore, system calibration must correspond to the intended target metallurgy to maintain amplitude accuracy and phase consistency.
