Real-World Applications for the 200150-20-05

In general industrial applications, this accelerometer monitors vibration on pumps, fans, compressors, and motors. Its 100 mV/g sensitivity captures both low- and high-frequency signals. The multiple approvals (CSA, ATEX, IECEx) allow use in hazardous environments. For example, a petrochemical plant can rely on the 200150-20-05 to detect early bearing wear and prevent catastrophic failure.

Installation and Setup Guide

Mount the accelerometer using the 3/8-24 female thread. Apply a mounting torque between 2.7 and 6.8 N•m (2 to 5 ft•lbf) for proper coupling. The 3/8-24 thread, 1 magnetic mount base option (stud option 20) simplifies temporary installations. Ensure the mounting surface is clean and flat to achieve the specified frequency response. After mounting, allow 24 hours cure time if using adhesive. Connect the excitation voltage between 4.7 and 5.5 Vdc. Verify the output bias voltage is +2.5 ± 0.23 Vdc before operation.

Maintenance and Reliability Tips

Regularly inspect the accelerometer cable and connector for damage. The hermetically sealed 316L stainless steel housing protects against moisture and corrosive atmospheres. Because the unit operates in 100% condensing humidity, verify the sealing integrity annually. Replace the unit if the output bias voltage drifts outside the specified range. This proactive approach extends service life and reduces unexpected downtime.

Compatibility and Integration

The 200150-20-05 works with Bently Nevada ProTIM option standard acceleration-to-velocity channel type (-01). It integrates into Trendmaster 2000 and Trendmaster Pro systems. The accelerometer outputs a positive signal (SIG+ positive with respect to SIG-) for acceleration from base to connector. For system-specific wiring details, consult the official Bently Nevada documentation.
