The 21504-000-020-10-02 is noncontacting, gap-to-voltage transducer systems that measure static as well as dynamic dis-tances between the probe tip and the observed target. The general application is any requircment for an accurate, non-contacting displacement mcasurement.
PPS Material Tip
Gold-Plated Connectors
Wide Temperature Range
The most common use is for shaft position and vibration measure-ments on rotating and reciprocating machinery. They are designed for use with virtually any machine type includ-ing gas and steam turbines, compressors pumps, centrifuges, electric motors and gencrators. The systems offer 80 mils (2 mm) of linear mcasuring range and are compatible with API 670 requirements.

Petrochemical Processing
Specifically used for radial vibration to indicate bearing condition and axial thrust position. It is designed to withstand unusually harsh, wet, and/or chemical environments.
Power Generation
Applied to monitor shaft average radial position and eccentricity in high-speed turbines. It provides critical data for vibration phase angle and bearing wear detection.
Natural Gas Transmission
Ideal for monitoring large compressors and rotating machinery in gas plants. The system functions reliably from -30°F to +350°F (-34°C to +177°C) in extreme field conditions.
Industrial Water Treatment The PPS (polyphenylene sulfide) probe tip is highly resistant to corrosive fluids. It is suitable for monitoring pumps and agitators operating in high-moisture or submerged environments.
Oil Refining
Used for continuous monitoring of critical rotating assets to prevent catastrophic failure. It measures both static and dynamic shaft motion with high precision and reliability.
Heavy Manufacturing
Appropriate for heavy-duty industrial machinery requiring long-term stability and EMI/RFI resistance. It supports a wide frequency response from 0 Hz (DC) to 10 kHz.
Operating on the eddy current principle, the proximity probe senses the distance between the probe tip and the observcd surfacc. The Proximitor generates a radio frequency signal, which is radiated through the probe tip into the observed surface. Eddy currents are generated in the surface, and the loss of strength in the return signal is detected by the Proximitor, which conditions the signal for linear display on a monitor.
The 5 mm and 8 mm systems use the same type of Proximitor. Both 5 and 9 metre Proximitors are available. A three- conductor, 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 dcgradation of performance.
What is the specific configuration of model 21504-000-020-10-02?
This model is a 7200 Series 8mm proximity probe with 0.0 in unthreaded length, 2.0 in overall case length, 1.0 metre (3.3 feet) total cable length, and a miniature male coaxial connector.
What is the linear measuring range of the 21504-000-020-10-02 probe?
The system offers a linear range of 80 mils (2.0 mm), which typically begins at approximately 10 mils (0.25 mm) from the probe face when used with an AISI 4140 steel target.
What material is used for the 8mm probe tip of the 21504-000-020-10-02?
The 8 mm probes are constructed of polyphenylene sulfide (PPS), a high-performance plastic capable of withstanding unusually harsh, wet, and/or chemical environments.
What are the environmental temperature limits for the 21504-000-020-10-02?
The probe and integral cable are designed to operate within a temperature range of -30°F to +350°F (-34°C to +177°C) according to official environmental limits.
What are the primary measurement applications for the 21504-000-020-10-02?
It is used for radial vibration to indicate bearing condition, axial thrust position for bearing wear, shaft average radial position, vibration phase angle, and eccentricity.
