200350-02-00-00 Bently Nevada Vibration Sensor 100mV/g

Product Overview

The 200350-02-00-00 is a high-performance seismic accelerometer engineered by Bently Nevada for demanding industrial vibration analysis. Manufactured in the USA, this sensor utilizes a shear-mode ceramic sensing element to deliver superior stability and reduced sensitivity to base strain and thermal transients. With a frequency response extending to 10 kHz, it is specifically designed to capture high-frequency mechanical faults such as gear mesh issues and early-stage bearing wear, providing the essential data required for modern predictive maintenance programs.

Technical Configuration

The 200350-02-00-00 configuration is tailored for international mechanical standards. The "02" mounting option features a 1/4-28 to M8 x 1.25 stainless steel adapter stud, allowing for seamless integration into machinery with metric mounting points. The "00" tolerance provides the industry-standard 100 mV/g (±20%) sensitivity, while the final "00" indicates a standard industrial version without specific hazardous area agency approvals. The unit features a top-exit 2-pin Mil-C-5015 connector and a rugged 11/16” hex base for secure installation in tight industrial spaces.

Technical Specifications

Installation & Maintenance Guide

For optimal high-frequency performance, the 200350-02-00-00 must be installed on a flat, machined surface with a maximum torque of 2.7 to 6.8 N-m (2 to 5 ft-lb). Ensure the M8 x 1.25 mounting stud is fully seated to prevent signal resonance that can occur at the 25 kHz resonant frequency. While the housing is IP68 rated and hermetically sealed, the 2-pin Mil-C-5015 connector should be protected from direct fluid spray or chemical contaminants to maintain electrical isolation (>10^8 ohms). A Certificate of Origin (COO) can be provided upon request for international shipping compliance.

Engineering Advantages

The 200350-02-00-00 excels in precision monitoring due to its ±1% amplitude linearity and exceptionally low transverse sensitivity (≤7%). The shear-mode sensing geometry ensures that the accelerometer remains unaffected by machine base bending or thermal expansion, which often cause errors in compression-style sensors. With a rapid settling time of 2.0 seconds and a low broadband electrical noise of 350 μg, this sensor provides clean, actionable data immediately upon power-up, even in electrically noisy industrial environments.

Technical FAQs

Q1: Can this sensor be used in wet or condensing environments?
A1: Yes, the IP68 rating and welded hermetic seal allow the sensor to operate in 100% condensing humidity. However, for continuous submersion, specialized waterproof cabling is required.

Q2: What excitation voltage is required for the 200350-02-00-00?
A2: The sensor requires a constant current excitation of 2 to 20 mA at a voltage range of 18 to 28 VDC, which is standard for most Bently Nevada monitoring systems.

Q3: What is the benefit of the Stainless Steel M8 mounting stud?
A3: The stainless steel construction offers high corrosion resistance and high stiffness, ensuring the mechanical connection does not degrade in harsh industrial settings, which is vital for maintaining frequency response accuracy.
