Bently Nevada 3300 XL 8mm Proximity Probe 330101-00-25-20-12-00

Technical Overview

The 330101-00-25-20-12-00 is a high-precision non-contacting transducer engineered for the Bently Nevada 3300 XL series. Designed specifically for critical machinery protection, this 8mm proximity probe provides accurate measurements of radial vibration and axial position. It plays a vital role in Turbine Supervisory Instrumentation (TSI) by monitoring shaft behavior in high-speed rotating equipment such as gas turbines, steam turbines, and centrifugal compressors.

The 330101-00-25-20-12-00 (Part Number: 330101-00-25-20-12-00) utilizes advanced eddy current technology to deliver a linear voltage output proportional to the gap between the probe tip and the target material. Its robust construction ensures long-term stability in harsh industrial environments, featuring enhanced resistance to moisture ingress and chemical exposure.

Key Features and Capabilities

• Precision Measurement: Offers a standard linear range of 2 mm (80 mils) with exceptional accuracy for both static and dynamic data acquisition.

• Environmental Resilience: The probe tip and cable are designed to withstand temperatures ranging from -51°C to +177°C, while the IP67-rated housing ensures protection in oil-mist environments.

• Interchangeability: Fully compatible with the 3300 XL Proximitor Sensor and extension cables, allowing for seamless integration without field calibration in most standard 4140 steel applications.

• Thermal Stability: Features an integrated compensation system that maintains signal integrity across varying thermal cycles, reducing drift in high-heat turbine housings.

• Safety Certifications: Rated for hazardous area installations with ATEX, IECEx, and CSA approvals, ensuring compliance in volatile Oil & Gas or Power Generation sectors.
