Product Overview

Sensor Design and Application

The Bently Nevada 200350-12-00-CN is an accelerometer from the 200350 series manufactured in the USA. Therefore, this sensor measures vibration in rotating and reciprocating machinery. The sensing element uses ceramic material in a shear geometry configuration. Consequently, the 200350-12-00-CN provides accurate acceleration measurements across a wide frequency range. The welded hermetic sealing ensures reliable operation in harsh environments.

Key Features and Benefits

The 200350-12-00-CN offers a sensitivity of 100 mV/g with ±20% tolerance. Therefore, it provides standard vibration measurements compatible with most monitoring systems. The frequency range extends from 30 to 600,000 cpm (0.5 to 10,000 Hz). Consequently, the sensor captures both low-frequency machinery vibrations and high-frequency bearing faults. The M8x1.25 adhesive stud mount enables installation on curved or irregular surfaces.
