Product Overview
The Bently Nevada 200150-09-05 is a general-purpose accelerometer designed for the Trendmaster 2000 and Trendmaster Pro systems. This industrial automation module delivers precise vibration measurements, enabling predictive maintenance and reducing unplanned downtime. With multiple approvals (CSA, ATEX, and IECEx), the 200150-09-05 meets rigorous safety standards for hazardous environments.
Each unit is manufactured in the U.S.A. and features a 3/8-24 to 3/4 NPT mounting stud option (09) and multiple approvals (05). The accelerometer is used with the ProTIM option standard acceleration-to-velocity channel type (-01), making it a versatile choice for general applications.

Applications
The 200150-09-05 is ideal for condition monitoring of pumps, motors, fans, compressors, and other rotating equipment. It integrates seamlessly with Trendmaster systems to provide continuous vibration monitoring, helping detect early bearing faults, unbalance, and misalignment. In general industrial plants, this accelerometer supports predictive maintenance programs that reduce unplanned outages and extend machinery life.
Installation & Setup
Mount the accelerometer using the 3/8-24 female thread. Apply a thin layer of coupling agent (e.g., silicone grease) for optimal frequency response. Tighten to the recommended torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). Ensure the mounting surface is flat and clean to avoid measurement errors. Connect the sensor to the ProTIM channel input, observing correct polarity (SIG+ positive).
Maintenance & Reliability
This accelerometer requires minimal maintenance. Periodically inspect the cable and connector for damage. Verify that the mounting stud remains tight. Because of the hermetic sealing and 316L stainless steel construction, the sensor provides long-term reliability even in humid or corrosive environments. Regular calibration checks (e.g., annually) help maintain measurement accuracy.
