Product Overview

• PN: 330703-000-070-10-02-05
• Brand: Bently Nevada (Baker Hughes)
• Series: 3300XL Non-Contact Proximity Transducer System
• Type: 14mm Linear Range Straight Exit Probe

• Function: Non-contact eddy current sensor converting clearance between probe tip and metal target into analog voltage signal. Cooperates with matched proximitor oscillator to transmit signals to monitoring modules, realizing real-time measurement of large-range shaft radial vibration and thrust axial position, executing over-limit alarm and safety interlock for heavy-duty rotating equipment.
