200157-06-05 | Bently Nevada Enveloping Accelerometer

The Bently Nevada 200157-06-05 is a Connector for industrial control and automation applications.

Bently Nevada 200157-06-05 is an Enveloping Trendmaster Pro accelerometer designed for roller element bearing monitoring and certain cavitation effects. It features a 3/8-24 to 1/4 NPT mounting stud option and multiple approvals (CSA, ATEX, IECEx).

What Is the 200157-06-05 Accelerometer?

This genuine Bently Nevada sensor is part of the Trendmaster Pro family. It provides a standard acceleration-to-velocity output with an acceleration enveloping channel type (-06). The accelerometer is made in the U.S.A. and uses a ceramic sensing element with shear geometry. Its hermetic sealing and wide temperature range support reliable operation in demanding industrial environments.

Comparison with Similar Product Categories

• vs. Standard accelerometers: This unit adds acceleration enveloping for early bearing fault detection, while standard units typically offer only raw acceleration.
• vs. Velocity transducers: This model provides acceleration-to-velocity output with a wider frequency range (10 to 10,000 Hz) than many velocity sensors.
• vs. Other Trendmaster Pro options: The -06 option specifically includes the enveloping channel, making it suited for roller element bearing monitoring.

Applications and Installation

This unit excels in monitoring roller element bearings and detecting cavitation effects. Its 3/8-24 female mounting thread and 3/4 inch hex stud allow secure installation. Mounting torque is 2.7 to 6.8 N·m (2 to 5 ft·lbf). The hermetic seal and 100% relative humidity rating (condensing, non-submerged) ensure durability.
