Description

Product Overview

The Bently Nevada 330104-00-12-10-11-00 is a high-precision 8mm proximity probe within the 3300 XL series, engineered to measure shaft vibration and position in critical rotating machinery. This industrial sensor provides non-contacting displacement measurements, ensuring accurate data for machinery protection systems in demanding environments.

Advanced Measurement Performance

This 3300 XL 8mm probe delivers a standard sensitivity of $7.87 V/mm$ ($200 mV/mil$), allowing for extremely precise detection of shaft movement. The sensor operates effectively within a broad temperature spectrum, maintaining signal stability from $-51°C$ to $+177°C$ ($-60°F$ to $+350°F$). Furthermore, Bently Nevada designed this probe with significantly improved resistance to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI). This technical advancement often allows for installation without expensive shielded conduits, thereby reducing overall deployment costs.

Engineering and Installation Flexibility

The 330104-00-12-10-11-00 model features a robust mechanical design that simplifies the retrofit of legacy vibration monitoring hardware. It supports multiple mounting configurations, including high-density DIN-rail and traditional 4-hole panel mounts. Because the system utilizes an isolated mounting base, it effectively prevents ground loops and electrical noise interference. Additionally, the probe’s frequency response ranges from $0 Hz$ (DC) to $10 kHz$, enabling it to capture both static position changes and high-frequency dynamic vibrations with equal reliability.

Compliance and Hazardous Area Reliability

This proximity probe meets stringent global safety standards, including ATEX and IECEx certifications for use in explosive or hazardous atmospheres. It functions optimally on $-24 VDC$ input power and produces a linear output signal typically between $-2$ and $-18 VDC$. Consequently, it has become a global standard for monitoring essential assets in oil and gas refineries, power generation facilities, and heavy industrial plants. The probe’s durable construction ensures long-term calibration stability, minimizing the need for frequent field adjustments.
