The Bently Nevada 200157-02-CN is a high-frequency acceleration enveloping accelerometer, typically used as a case-mounted seismic transducer with Trendmaster ProTIM systems for industrial vibration monitoring. It is designed for identifying bearing faults, featuring a wide frequency range and specialized approvals for hazardous environments.

The 200157 Accelerometers feature a hermetically sealed, stainless steel case. This design provides an extremely rugged transducer that is well-suited for harsh industrial environments. The transducer’s top-mounted, 5-pin connector allows for easy installation and removal of the interconnecting signal cable. A 3/8-24 threaded hole on the bottom of the sensor’s casing accommodates several mounting options.

The 200157 Accelerometers contain a piezoelectric sensing device that generates a charge when subjected to vibration. The accelerometers electronically convert this charge to a differential voltage signal, which is proportional to the acceleration parallel to the sensitive axis of the transducer.
