Product Introduction
The Bently Nevada 137365-01-20-02-05 Proximity Probe is an industrial sensor used in machinery monitoring systems to measure shaft position and vibration without direct contact. Rotating equipment such as turbines, compressors, and motors operate under conditions where precise monitoring of shaft movement is necessary to prevent mechanical damage.
The probe detects changes in distance between its sensing tip and the rotating shaft surface. These measurements are transmitted to monitoring systems that analyze machine condition and trigger alarms if abnormal behavior is detected.
With flexible length options and compatibility with industrial monitoring infrastructures, the probe supports reliable measurement in demanding machinery protection applications.
