Product Overview

The Bently Nevada 200350-02-00-01 is a high-performance, general-purpose accelerometer designed for casing vibration monitoring on rotating machinery. Unlike proximity probes that observe shaft displacement, this sensor measures the absolute vibration acceleration of the machine housing. It utilizes a piezoelectric sensing element to convert mechanical motion into a precise electrical signal. This module serves as a frontline diagnostic tool for identifying high-frequency faults such as gear mesh issues, cavitation in pumps, and rolling-element bearing degradation in turbines and compressors.

Part Number Breakdown: 200350-AA-BB-CC

The 200350 series follows a modular ordering structure to meet specific global industrial requirements:

• 200350 (Base Model): General Purpose Accelerometer.

• -02 (Mounting Stud): Includes a 1/4-28 to M8 x 1.25 Beryllium Copper (BeCu) adapter stud.

• -00 (Tolerance/Sensitivity): Calibrated to 100 mV/g ±20%.

• -01 (Approvals): Multiple international agency approvals for hazardous area installations.

• -CN (Optional): Country-specific approvals for the Chinese market.

Technical Specifications

The 200350-02-00-01 offers a wide frequency response and a compact form factor for versatile mounting.

Engineering Advantages

• Optimized Mounting Architecture: The -02 option provides a Beryllium Copper (BeCu) mounting stud. This material ensures superior acoustic coupling between the machine casing and the sensor, reducing signal attenuation at higher frequencies compared to standard steel studs.

• Direct Casing Diagnostics: The 200350-02-00-01 excels at capturing "stiffness-controlled" vibration. This makes it the primary choice for monitoring machines with rolling-element bearings where shaft-to-casing vibration transmission is high.

• Hazardous Area Readiness: The -01 and -CN approval options certify the sensor for use in explosive atmospheres. This allows for safe deployment in refineries, chemical processing plants, and offshore platforms without additional shielding requirements.

• Rugged Environmental Sealing: The stainless-steel housing and MIL-style connector interface resist moisture ingress and chemical exposure. The sensor maintains calibration stability even under the continuous thermal cycling found in industrial pump and motor rooms.

FAQs

Q: Is the 200350-02-00-01 supplied as 100% Brand New?

A: Yes. We supply only 100% Brand New and Original Bently Nevada hardware in original factory packing. Every unit includes a 12-month factory warranty. A Certificate of Origin (COO) can be provided upon request.

Q: What is the difference between this accelerometer and a Velomitor?

A: While they look similar, the 200350 is an accelerometer outputting in mV/g (Acceleration), whereas a Velomitor (like the 330500) contains internal integration circuitry to output in mV/mm/s (Velocity). The 200350 is superior for detecting high-frequency bearing and gear noise.

Q: Does the package include the mounting stud?

A: Yes, the -02 suffix confirms the inclusion of the 1/4-28 to M8 x 1.25 BeCu mounting stud. This allows you to mount the sensor directly into metric-threaded machine casings.

Q: What is the estimated lead time for this product?

A: Due to high global demand and specialized factory calibration, the typical lead time is 8 to 10 weeks. We recommend planning maintenance outages accordingly.
