Description

Technical Overview

The Bently Nevada 330707-00-25-10-02-00 is a high-precision 3300 XL 11 mm proximity probe engineered for mission-critical shaft vibration and position monitoring in industrial rotating machinery. Designed for integration with the industry-standard 3300 XL 25 mm and 50 mm sensor systems, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—ensuring reliable performance in demanding environments such as power generation, oil & gas, petrochemical, and heavy manufacturing facilities. Its robust construction features a stainless steel housing and high-temperature epoxy encapsulation, enabling continuous operation across extended temperature ranges and harsh mechanical conditions.

This probe operates on the eddy-current principle and is optimized for use with Bently Nevada’s 3300 XL 11 mm preamplifiers (e.g., 3300 XL 11 mm Proximitor®). It provides a linear output voltage proportional to the distance between the probe tip and the target surface—enabling accurate, real-time measurement of shaft displacement, runout, and dynamic vibration. With a nominal sensing range of 2.5 mm and a sensitivity of 4.0 V/mm, the 330707-00-25-10-02-00 supports stringent API 670 and ISO 10816 compliance requirements for machinery protection systems. Its precision-machined 11 mm diameter probe tip ensures consistent field performance, even under high-speed rotational dynamics and varying surface finishes.

Key Features

• High Accuracy & Repeatability: Maintains ±1% full-scale linearity and sub-micron resolution over its operational range, critical for predictive maintenance and condition-based monitoring.
• Rugged Industrial Design: IP68-rated stainless steel body with integral 5-meter coaxial cable (RG-178/U), rated for continuous exposure to oil, steam, and corrosive atmospheres.
