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.
Applications
Mount on Rotating Shafts for Distance Monitoring
The 21508-02-12-05-02 3300 XL 8mm Proximity Probe mounts directly on shafts or machinery housings to measure static and dynamic distances up to 80 mils, feeding real-time vibration data to automated monitoring systems.
Connect to Data Acquisition Modules
The 21508-02-12-05-02 3300 XL probe transmits 0–10 kHz vibration signals through its 0.5 m coaxial cable to Proximitor or data acquisition inputs for automated diagnostic analysis.
Monitor Industrial Pumps and Motors
Using the 21508-02-12-05-02 3300 XL 8mm Proximity Probe, vibration and distance data from pumps and motors can be logged continuously to track operational performance in automated control systems.
Enable Predictive Maintenance Alarms
The 21508-02-12-05-02 3300 XL probe provides high-frequency measurements and accurate scale factor data, allowing automated systems to trigger maintenance alerts before machinery failures occur.
