Features:
- Interface Between the 25 mm Probe, Extension Cable, and Monitoring System
- Combines High-Precision Signal Conditioning with Extended Linear Range Capability
- Operates in Conjunction with the 3300 XL 25 mm Transducer System and Bently Nevada Monitoring Platforms
The 330850-50-00 operates as the Proximitor Sensor in the 3300 XL 25 mm Transducer System, providing reliable signal conditioning and conversion for all measurement components within the chain. It continuously processes the eddy current signal from the 25 mm probe and extension cable, converting it into a precise 0.787 V/mm (20 mV/mil) output to support accurate position and vibration monitoring of rotating machinery. Seamless signal integration is standard with the 330850-50-00, however using proper system calibration will ensure optimal linearity across the full 12.7 mm (500 mils) measurement range in demanding industrial environments.
The 330850-50-00 provides essential signal conditioning functions common to the entire transducer system, and is a critical component of the measurement path, directly affecting the proper, normal operation of the overall monitoring system. One 330850-50-00 Proximitor Sensor is required per measurement channel depending on the specific application requirements. The 330850-50-00 is typically mounted in a protected enclosure near the machine train and connected to the monitoring rack via standard coaxial cabling.
For Differential Expansion (DE) measurement applications, the 3300 XL 25 mm Transducer System requires the 330850-50-00 Proximitor Sensor installed with the appropriate 25 mm probe and extension cable. In addition to standard position measurement operation, the differential expansion configuration also performs continuous growth rate monitoring. The 330850-50-00 measurement chain executes accurate DE tracking using the internal circuitry specified in the proximitor design. Using this method, the 330850-50-00 continually monitors the relative thermal growth between the turbine rotor and machine stator.
The 330850-50-00 Bently Nevada 3300 XL 25 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Differential Expansion (DE): It measures the physical growth difference between a spinning turbine rotor and its stationary outer casing during thermal changes.
- Turbine Supervisory Instrumentation (TSI): It functions as a critical safety data link for automated machine shutdown and protection networks.
- Large Asset Monitoring: It tracks axial thrust position on massive steam turbines, heavy compressors, and large fluid-filmed bearing pumps.
- System Length Match: The -50 option dictates that this sensor requires a 3300 XL 25 mm probe and extension cable that equal an exact total electrical length of 5.0 meters.
- Output Scale Factor: The device delivers a linear voltage output of 0.787 V/mm (200 mV/mil) across a total measurement range of 12.7 mm (500 mils).
- Target Calibration: The system is calibrated at the factory for AISI 4140 steel targets. Other target metals require a scale adjustment factor inside your monitoring rack.
- Physical Installation: The unit features a panel-mount base design. It has the same physical footprint as older legacy systems for quick drop-in replacement.
- Approval Rating (-00): The -00 suffix specifies that this unit carries no hazardous area certifications. It must only be installed in safe, non-hazardous locations.
- Electrical Isolation: The integrated plastic mounting base electrically isolates the sensor from the physical mounting plate to prevent ground loop interference.
- Vibration Resistance: Field wiring connects via SpringLoc terminal strips. This design prevents wires from vibrating loose over long periods of machine operation.
- Signal Protection: The housing resists radio frequency and electromagnetic interference. It can operate inside non-metal enclosures without losing signal quality.
