Applications
• Used on centrifugal compressors to monitor axial thrust and help prevent rotor-to-stator contact during unstable operating conditions
• Applied in pump systems where axial displacement needs to be translated into a standard control signal for PLC/DCS logic
• Used in fan and motor assemblies for basic thrust indication in packaged OEM machinery systems
• Integrated into skid-mounted industrial equipment where compact thrust monitoring is required without full vibration rack systems
• Used in general rotating machinery where reliable axial position feedback is needed for protection and shutdown logic
Key Advantages
• Converts axial shaft movement into a stable 4–20 mA output for direct control system use
• Works with Bently Nevada 3300 NSv proximity probe input for consistent measurement behavior
• Loop-powered design reduces wiring effort and simplifies field installation
• Compact transmitter housing fits easily into OEM panels and tight control cabinet spaces
• Signal conditioning is stable enough for continuous industrial operation
• Practical solution for applications that do not require full diagnostic monitoring systems
Technical FAQs
