Product Overview

• PN: 330104-00-05-10-02-00
• Brand: Bently Nevada (Baker Hughes)
• Series: 3300XL Non-Contact Proximity Transducer System
• Type: 8mm Linear Range Straight Exit Probe

• Function: Non-contact eddy current sensor converting gap distance between probe tip and metal target into analog voltage signal. Cooperates with supporting proximitor to transmit signals to monitoring modules, realizing real-time measurement of shaft radial vibration and axial thrust displacement, and triggering alarm and interlock protection when values exceed preset limits.
