Applications
• Used for axial displacement (thrust position) monitoring in rotating machinery such as compressors and small turbines.
• Applied in pumps, motors, and fans where continuous thrust measurement is required for protection logic.
• Common in OEM machinery packages that require direct 4–20 mA output for control system integration.
• Used in industrial automation systems to feed axial position data into PLC or DCS platforms.
• Suitable for compact equipment designs where simplified wiring and transmitter integration are preferred.
Key Advantages
• Converts proximity probe signals into a direct 4–20 mA thrust output for control systems.
• Integrated transmitter design reduces the need for separate monitoring modules.
• Stable performance under continuous industrial operating conditions.
• Compatible with Bently Nevada 3300 NSv proximity probe systems.
• Compact form factor supports easy installation in OEM machinery panels.
