Applications
• Used on centrifugal compressors to monitor axial thrust position and prevent rotor contact during load changes
• Applied in pumps and small rotating equipment where axial displacement needs to be converted into a 4–20 mA signal
• Used in motors and fan systems for basic thrust indication in OEM control and protection packages
• Integrated into packaged machinery skids where simplified thrust monitoring is preferred over full diagnostic systems
• Used in industrial systems where compact installation and direct control-system input are required
Key Advantages
• Converts axial shaft movement directly into a 4–20 mA output for easy PLC or DCS integration
• Designed for use with 3300 NSv proximity probe systems for stable measurement input
• Loop-powered design reduces wiring complexity and simplifies field installation
• Compact transmitter structure fits well in OEM panels and skid-mounted equipment
• Stable signal conditioning helps reduce noise influence in industrial environments
• Suitable for continuous monitoring of thrust position in rotating machinery
Technical FAQs
Q1: What is the main function of this device?
It converts shaft axial displacement (thrust) into a standard 4–20 mA signal.
Q2: What probe system does it work with?
It is used with Bently Nevada 3300 NSv proximity probes and matching cables.
Q3: Is it a standalone sensor?
No, it requires an external proximity probe input.
Q4: Where is it typically used?
On compressors, pumps, motors, and fan systems.
Q5: Does it output vibration signals?
No, it outputs axial thrust position only.
Q6: Is it suitable for OEM systems?
Yes, it is widely used in OEM machinery packages.
Q7: Does it require external power?
It is loop-powered (2-wire 4–20 mA configuration).
Q8: Can it be used for protection logic?
Yes, it is commonly used as an input for control and shutdown logic.
Q9: Does it require calibration after replacement?
Normally no field calibration is required if installed correctly.
Q10: What is its main limitation?
It provides basic thrust monitoring, not advanced vibration diagnostics.
