Product Information:

The 330851-04-000-030-10-00-05 is the Bently Nevada 3300 XL 25mm eddy current displacement sensor probe. As a core industrial-grade sensing element, it utilizes the eddy current principle and is designed for high-precision, non-contact online monitoring of shaft vibration, shaft displacement, and thermal expansion in rotating machinery such as steam turbines, gas turbines, and large compressors. It is a critical component ensuring the safe operation of large industrial equipment.

The hardware specifications of the 330851-04-000-030-10-00-05 are defined by a strict coding system: it uses an M30x2 threaded housing with a cable outlet on the side; the housing length is 30mm, and all connections are threaded (no non-threaded connections); in addition, it includes a 1-meter unarmored cable. This compact design makes it ideal for installation in space-constrained large bearing housings or inside machinery.

Regarding safety and compliance, the suffix "05" in hardware configuration 330851-04-000-030-10-00-05 indicates that it has obtained multiple national/international explosion-proof safety certifications (such as ATEX, IECEx, etc.). This means that the probe can be safely used in high-risk industrial environments containing flammable and explosive gases or dust.

Features:

  • 3300 XL 25 mm Proximity Probe
  • 3300 XL 25mm Proximity Transducer System
  • Bently Nevada Machinery Condition Monitoring
The 3300 XL 25 mm probe is designed for maximum survivability in the harshest steam turbine DE environments. It can continually operate and maintain its accuracy in high temperatures up to 200 °C (392 °F), and can withstand intermittent high temperatures up to 250 °C (482 °F). The 25 mm probe has both a front and rear seal which, combined with the FluidLoc cable (standard on all 25 mm probes), prevents moisture from entering the probe tip. Special high-temperature ClickLoc connectors are also standard on the probe and extension cable. Each probe and cable are provided with connector protectors and a disposable connector protector installation tool to ensure that the connectors remain free of contamination.

The ClickLoc connector on the probe lead has a removable collar that facilitates routing the cable through tight clearances. The 3300 XL 25 mm probe is available in many probe case styles, including 1¼-12 or 1½-12 English threads, M30x2 or M39x1.5 metric threads, or side or rear exit probes with a 1.06 or 1.50 in diameter smooth probe case. Additionally, threaded 3300 XL 25 mm probe cases come standard with a locknut with predrilled safety wire holes.

The 330851-04-000-030-10-00-05 Bently Nevada 3300 XL 25 mm Proximity Probe may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

To build a complete functional loop using this probe, you will need to use it with compatible components from the Bently Nevada 3300 XL 25 mm sensor system family:
 
Total System Length: This probe uses a 1-meter cable, meaning it must be used with a 4-meter or 8-meter extension cable to form a standard 5-meter or 9-meter measurement system.
Proximity Sensor: A 3300 XL 25 mm proximity sensor is required that matches your chosen total system length (5 meters or 9 meters). This sensor is calibrated to convert eddy current changes into a linear voltage signal.
