Product Overview

• PN: 330104-00-05-10-02-CN
• 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 that converts the gap distance between probe tip and rotating metal target into continuous analog voltage signal. Paired with matching proximitor oscillator, it transmits signals to monitoring modules to realize real-time measurement of shaft radial vibration, axial thrust displacement and shaft position, supporting equipment over-limit alarm and safety interlock protection for critical rotating units.
