Bently Nevada 21504-000-008-05-02 7200 Proximity Transducer Systems 8mm Stand Mount Probe
Description:
21504-000-008-05-02 is Bently Nevada 7200 Proximity Transducer Systems Improved proximity probes. 21504-000-008-05-02 is 8mm Stand Mount Probe, 3/8-24 UNF thread, 0.5 meter cable length with miniature male coaxial connector.

The 7200 5 mm and 8 mm ProximityTransduccr Systems arc noncontacting, gap-to-voltage transducer systems that measure static as well as dynamic distances between the probe tip and the observed target.The general applicationis 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 gencrators. The systems offer 80 mils(2 mm) of linear measuring range and are compatible with API 670 requirements.

A system consists of a probe with integral coaxial cable, an extension cable, and Proximitor. All 7200 proximity transducer systems are compatible with3300 and 9000 Monitoring 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.

Tvo new cable length options are now available on 8 mm probes. They are 5metres 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 areavailable to accommodate English and metric thread requirements. The 8 mm probes are construeted 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 scalefactor of 200 mV/mil (8 V/mm).

Specifications:
Specifications were determined with a-24 Vdc power supply, 10 kΩ load, and an AISI 4140 steel target at + 72°F(+22°C).
INPUT Power: -17.5 Vdc to -26 Vdc at 12 mA maximum consumption.
OUTPUT Calibrated Range:  80 mils (2.0 mm). Begins at approximately 10 mils(0.25 mm) from probe face.
Scale Factor: 200 mV/mil (7.87 V/mm), ±4%(measured in increments of10 mils over the calibrated range) if calibrated as a system. Within ±9.5% including interchangeability errors.
Linearity: Within 0.8 mils (0.02 mm) of a 200 mV/mil straight line if calibrated as a system. Within 2.3 mils (0.06 mm) of a 200 mV/mil straight line including interchangeability errors.
Frequency Response: 0 to 10 kHz(0 to 600,000 cpm); -596 at 10 kHz(600,000 cpm).
Temperature Sensitivity: Typically -3% change in scale factor at + 150oF(+65°C) at 50 mils gap(1.27 mm).
