　　II. Product Overview

The 330130‑070‑01‑05 belongs to the 3300XL 8mm series eddy current probe and is a core component of Bentley’s proximity sensor system. The probe, along with the extension cable and preamplifier, forms a complete sensor system, converting changes in the gap between the probe and the shaft surface into a voltage signal for online measurement of shaft vibration, shaft displacement, key phase, and speed in rotating machinery. Widely used in large units such as steam turbines, compressors, fans, and pumps, as well as power plants, petrochemical plants, and oil refineries, it is a key sensor spare part for unit condition monitoring and interlocking protection.

　　III. Functional Features

8mm eddy current measurement principle, 7.87V/mm standard sensitivity, stable linear range, high measurement accuracy. Complete 10-meter integrated cable, ClickLoc quick-lock coaxial connector, tensile strength resistant, high cable tensile strength. Stainless steel probe housing, PPS probe head, high temperature resistance, oil and water vapor resistance, suitable for power plant and petrochemical unit internal operating conditions. Measures dynamic vibration and static shaft displacement, and supports key phase speed acquisition. The entire sensor assembly is interchangeable; probes, cables, and preamplifiers do not require pairing calibration. EMI/RFI immunity, suitable for strong electromagnetic field environments. Meets API-670 petroleum industry machinery protection standards, data access to 3500 and other monitoring frameworks, enabling alarm and interlock protection outputs.

　　IV. Applications and Operation

Mainly used for condition monitoring and protection of rotating machinery such as steam turbine units, compressor units, fans, and water pumps. The probe, with an M8 thread, is installed on the probe bracket in the unit’s bearing housing, with the probe head aligned with the metal surface of the shaft being measured. A coaxial cable runs to the preamplifier, which in turn connects to the 3500 monitoring module. When the system is powered on, the preamplifier provides -17.5~-26VDC power. The probe collects changes in shaft clearance and outputs a corresponding voltage signal. The monitoring module performs vibration and displacement calculations, enabling display, alarm, and interlocking. When replacing parts, screw in the new probe, adjust the clearance voltage to the appropriate operating point, and tighten the lock nut. Verify the clearance voltage, check the vibration and displacement readings, test the alarm and interlocking functions, and confirm that everything is correct before putting it into unit operation.

　　V. Design and Structure

Stainless steel threaded housing, M8×0.75 standard mounting thread, matching lock nut. Probe head PPS insulation material, built-in induction coil. Integrated 10-meter shielded coaxial signal cable, oil-resistant and high-temperature resistant. ClickLoc miniature coaxial quick-lock connector for connecting extension cables or the preamplifier. The probe features an integrated sensing unit, facilitating easy disassembly and replacement, and reducing unit downtime for maintenance.

　　VI. System Features

Natively compatible with the Bently 3300XL preamplifier and 3500 series monitoring frame, components are interchangeable and compatible. 0-10kHz wideband response, accommodating both low-frequency displacement and high-frequency vibration acquisition. Minimal temperature drift, maintaining measurement accuracy across a wide temperature range within the unit. Resistant to internal oil mist, high temperatures, and vibration conditions, supporting long-term uninterrupted online monitoring. Probes, cables, and preamplifiers can be combined arbitrarily without separate pairing calibration, facilitating convenient on-site replacement. Widely used in existing systems, it is a mainstream spare part for petrochemical power plant unit maintenance and replacement.

　　VII. Warranty Information
