Description

21508-02-12-05-02 is a Probe Proximity Vibration developed by Bently Nevada. It is a part of the Bently Nevada 7200 5mm / 8mm Series Proximity Transducer System. The Bently Nevada 7200 5mm / 8mm Series Proximity Transducer Systems are non-contacting, gap-to-voltage transducer systems that measure static and dynamic distances between the probe tip and the observed target. The general use is any circumstance requiring an accurate, non-contact displacement measurement. However, the most prevalent application is for shaft position and vibration measurements on rotating and reciprocating machinery. They are intended for use with nearly any machine type, including gas and steam turbines, compressors, pumps, centrifuges, electric motors, and generators. The system has an 80 mil (2 mm) linear measuring range and is API 670 compliant.

Applications

Mount 21508-02-12-50-02 Probe on Rotating Shafts for Vibration Measurement
The 21508-02-12-50-02 Probe Proximity Vibration mounts directly on turbines, compressors, pumps, motors, or generators to measure static and dynamic displacement up to 80 mils (2.0 mm). Its DC–10 kHz frequency response supports automated vibration monitoring and high-speed shaft position tracking in industrial automation systems.

Connect 21508-02-12-50-02 Probe to Proximitor Inputs for Data Collection
The 21508-02-12-50-02 probe transmits 200 mV/mil signals through its 0.5 m integrated miniature coaxial cable to Proximitor or data acquisition modules, enabling real-time analysis for automated diagnostics.

Monitor Industrial Machinery with 21508-02-12-50-02 Probe
The 21508-02-12-50-02 Probe Proximity Vibration continuously records displacement and vibration data from turbines, pumps, compressors, motors, and generators, feeding automated monitoring systems for predictive maintenance.

Trigger Automated Maintenance Alerts Using 21508-02-12-50-02 Probe Data
The 21508-02-12-50-02 probe allows automated systems to detect abnormal shaft movement or vibration deviations (up to 600,000 cpm) and initiate maintenance actions before equipment failures occur.
