21747-085-00 - Proximitor Probe Extension Cable

SPECIFICATIONS

Part Number: 21747-085-00
Manufacturer: Bently Nevada
Country of Manufacture: United States (USA)
Product Type: Proximity Probe Extension Cable

21747-085-00 is a Proximitor Probe Extension Cable manufactured by Bently Nevada. It is an Extension Cable for the 7200 Proximity Transducer System. The 5mm and 8mm systems use the same type of proximitor. Both 5 and 9 proximitors are available. A 3 conductor, shielded cable provides the signal output and power source input between 7200 proximitors and Bently Nevada monitors. Operating on the eddy current principle, the proximity probe senses the distance between the probe tip and the observed surface. The 7200 system is currently in Phase 4 of obsolescence, and spare parts and system production are being discontinued.

Functional Description

• The non-contacting, gap-to-voltage 7200 5 mm and 8 mm Proximity Transducer Systems assess both static and dynamic distances between the probe tip and the target being examined.
• Any necessity for an exact, non-contacting displacement measurement falls within the general application. The most typical application, however, is for vibration and shaft position measurements on rotational and reciprocating machinery.
• They are made to work with almost any kind of machine, including electric motors, generators, pumps, centrifuges, gas and steam turbines, compressors, and turbines. The systems are in compliance with API 670 specifications and have a linear measuring range of 80 mils (2 mm).

Applications

The following types of measurements can be made using the 7200 5 and 8 mm Systems, which have a frequency response of 0 Hz (DC) to 10 kHz:

• Radial vibration is used to detect bad bearings and mechanical issues such as rotor imbalance and misalignment.
• Axial thrust position for assessing the wear or potential failure of the thrust bearings.
• An indicator of rotor stability is the shaft's average radial position, which is used to calculate attitude angle.
• Vibration amplitude and phase angle for Polar and Bode formats of plotting diagnostic data.
• Use of eccentricity to gauge rotor bow

Weight

• 0.23 Kg
