Product Overview

The 22810-00-05-10-02 is a high-performance proximity sensor engineered by Bently Nevada for the 7200 and 3300 series monitoring systems. This transducer is designed to provide high-fidelity, non-contact measurements of shaft vibration and position in critical rotating machinery. By utilizing an eddy current sensing principle, it translates the gap between the probe tip and the target surface into a precise voltage signal. This specific model features an integrated 2-foot (approximately 0.5-meter) lead cable, optimized for installations where a shorter integral connection is preferred before transitioning to an extension cable. It serves as a foundational component for Turbine Supervisory Instrumentation (TSI), ensuring real-time data for machinery protection and predictive maintenance.

Core Industrial Deployment Scenarios

This proximity probe is a versatile solution for various high-speed machinery monitoring needs:

• Radial Vibration Analysis: Measuring the side-to-side movement of shafts in centrifugal pumps and industrial fans to identify unbalance or misalignment.

• Axial Thrust Measurement: Monitoring the longitudinal position of rotors in steam turbines to prevent catastrophic internal contact.

• Phase Reference (Keyphasor): Providing high-accuracy timing pulses for rotational speed tracking and phase angle diagnostics.

• Oil & Gas Compression: Ideal for reciprocating and centrifugal compressors where precise gap measurement is required in oily, high-temp environments.

• Power Generation: Protecting base-load generators and large-scale electric motors through continuous condition monitoring.

FAQ

Q: How does the TipLoc molding benefit the sensor's performance?

The TipLoc molding creates a chemical and mechanical bond between the probe tip and the body that is significantly stronger than traditional adhesives, preventing the tip from detaching under extreme vibration or pressure.

Q: Can this probe be installed without a separate electrical isolator plate?

Yes, the 22810-00-05-10-02 is designed with internal electrical isolation at the mounting base, which simplifies the installation process and reduces the overall footprint of the sensor assembly.

Q: Is this probe compatible with standard 3300 XL Proximitors?

This probe is primarily a 7200 series design; while it can interface with various Bently Nevada monitors, you must ensure your Proximitor is calibrated for the specific scale factor of a 7200-style 8mm probe.

Q: Does the 0.5-meter cable require special protection?

While the integral cable is robust, in areas of high mechanical risk or extreme abrasion, it is recommended to use a stainless steel armored extension cable or flexible conduit to protect the signal path.

Q: Why is RFI/EMI immunity important for this probe?

High RFI/EMI immunity ensures that the vibration data is not distorted by radio signals or electromagnetic fields from nearby motors and variable frequency drives, which is essential for preventing false alarms.
