200350-02-00-01 Bently Nevada Hazardous Area Accelerometer

Product Overview

The 200350-02-00-01 is a premium seismic accelerometer designed by Bently Nevada for high-fidelity vibration monitoring in classified hazardous locations. Utilizing advanced shear-mode ceramic sensing technology, this transducer provides superior immunity to thermal transients and base strain, ensuring that your vibration data remains accurate even in fluctuating industrial conditions. With a 10 kHz frequency range, it is optimized for detecting early mechanical failures in high-speed turbines and compressors, allowing for proactive maintenance in environments where safety and reliability are non-negotiable.

Technical Configuration

The 200350-02-00-01 is specialized for international safety and mechanical standards. The "02" suffix denotes the inclusion of a 1/4-28 to M8 x 1.25 stainless steel adapter stud, facilitating installation on metric-threaded machinery. The "00" tolerance provides a calibrated 100 mV/g (±20%) output, while the critical "01" agency approval option certifies the unit for use under CSA, ATEX, and IECEx regulations. The sensor is built with a top-exit 2-pin Mil-C-5015 connector and a rugged 304 stainless steel housing, ensuring long-term hermetic integrity in the most challenging field conditions.

Technical Specifications

Installation & Maintenance Guide

To achieve the specified frequency response with the 200350-02-00-01, the mounting surface must be clean and machined flat. The M8 x 1.25 stainless steel stud should be torqued between 2.7 and 6.8 N-m (2 to 5 ft-lb) to ensure a rigid mechanical path. In hazardous area installations, it is mandatory to use the sensor in conjunction with an appropriately rated intrinsic safety barrier. While the IP68 rating allows for operation in 100% condensing humidity, the electrical connector should remain clean and dry during installation to maintain an isolation resistance of >10^8 ohms. A Certificate of Origin (COO) is available upon request for customs compliance.

Engineering Advantages

The 200350-02-00-01 excels in precision diagnostics due to its tight ±1% amplitude linearity and low transverse sensitivity (≤7%). The ceramic shear geometry significantly reduces error caused by machine base strain, a common issue in large industrial pumps and motors. Furthermore, the sensor features a rapid 2.0-second settling time and exceptional shock survivability of 5,000g peak, making it a robust choice for monitoring reciprocating machinery or assets prone to transient impact events.

Technical FAQs

Q1: What does the "01" agency approval option cover?
A1: The "01" option provides certifications for CSA, ATEX, and IECEx, making the 200350-02-00-01 suitable for intrinsically safe installations in Zone 0, 1, or 2, as well as various North American classes and divisions.

Q2: Can this sensor monitor very low-speed machinery?
A2: Yes, with a frequency response starting at 0.5 Hz (30 cpm), it can detect low-frequency vibrations typical of hydroelectric turbines or large industrial fans.

Q3: Why is the housing made of welded stainless steel?
A3: The welded hermetic construction provides an IP68 rating, protecting the internal ceramic elements from chemical ingress and moisture, which is critical for long-term reliability in harsh oil and gas environments.
