200350-00-00-00 Bently Nevada 10kHz High Frequency Sensor

Product Overview

The 200350-00-00-00 is a rugged, hermetically sealed industrial accelerometer designed by Bently Nevada for continuous vibration data collection. This sensor is optimized for a broad range of applications, providing the high-fidelity signal needed to monitor turbines, motors, and gearboxes. By converting mechanical acceleration into a proportional 100 mV/g electrical output, it enables maintenance teams to identify high-frequency faults such as bearing degradation or gear mesh issues. Its robust design ensures that even in high-vibration environments, the sensor provides stable and repeatable measurements for long-term asset health tracking.

Technical Configuration

The 200350-00-00-00 represents the standard configuration of the 200350 series, prioritizing broad compatibility and mechanical durability. The first "00" suffix specifies a 1/4-28 stainless steel mounting stud (0.5" length) featuring a brass tip for optimized surface contact. The second "00" indicates a standard ±20% sensitivity tolerance, while the final "00" confirms the model is a standard version without specific regional agency approvals. The unit's welded stainless steel housing is rated to IP68, ensuring complete protection against dust and moisture ingress, which is vital for outdoor or wash-down industrial locations.

Technical Specifications

Installation & Maintenance Guide

For the 200350-00-00-00 to perform at its specified 10 kHz limit, it must be installed on a properly prepared, flat-machined surface. The 1/4-28 mounting stud should be torqued precisely to ensure rigid mechanical coupling, as any looseness will attenuate high-frequency signals. Because this model features an IP68-rated hermetic seal, it can be used in submerged or extremely damp conditions; however, cabling should be protected with conduit if mechanical abrasion or chemical exposure is expected. A 12-month calibration interval is recommended to account for the typical <2% annual drift.

Engineering Advantages

The primary engineering advantage of the 200350-00-00-00 is its rapid thermal stabilization, reaching a stable bias shift of ±1% in less than 5 seconds. This allows for immediate, accurate data collection upon system startup. With an output impedance of less than 150 Ω and a wide excitation range (18–28 VDC), it integrates seamlessly with most industrial vibration monitors and DAQ systems. Its low broadband noise (350 μg) and tight transverse sensitivity (≤ 7%) ensure that the vibration data represents true machine motion with minimal interference from cross-axis forces.

Technical FAQs

Q1: What is the significance of the brass tip on the mounting stud?
A1: The brass tip provides a slightly softer interface than stainless steel, which helps in creating a more conforming mechanical contact between the sensor base and the machine casing, improving high-frequency transmission.

Q2: Can this accelerometer be used in hazardous areas?
A2: This specific "00" agency approval version is intended for non-classified areas. For installations requiring ATEX or IECEx certifications, a version with the appropriate agency approval suffix must be selected.

Q3: How does the IP68 rating benefit my application?
A3: IP68 means the sensor is completely dust-tight and protected against long-term immersion in water under pressure, making it ideal for cooling tower fans or wastewater treatment pumps.
