Non-contact displacement sensing: Measures the gap between the probe tip and a conductive target (shaft, collar, or ramp) using eddy-current technology.

Shaft position measurement: Provides continuous monitoring of rotor axial and radial position in rotating machinery.

Vibration detection (system-level function): Enables measurement of dynamic shaft motion when used with a 3300 XL Proximitor Sensor and monitoring system.

Differential expansion (DE) monitoring support: Used in turbine applications to track thermal growth differences between rotor and stator components.

Signal generation for monitoring systems: Works with the Proximitor Sensor to convert mechanical displacement into a proportional voltage signal for control and protection systems.

Wide linear measurement capability: Supports accurate measurement over a long linear range suitable for large industrial turbines.

High-temperature operation capability: Designed for stable operation in harsh environments such as steam turbines with elevated temperatures.

Mechanical robustness for industrial use: Sealed probe design with FluidLoc cable to resist moisture ingress and maintain measurement reliability.

Flexible installation compatibility: Supports threaded or smooth case configurations for different turbine and machinery mounting requirements.

System integration compatibility: Fully compatible with Bently Nevada 3300 XL monitoring systems and backward-compatible with legacy 7200-series systems.
