200155-01-05 | Bently Nevada Low Frequency Accelerometer

The Bently Nevada 200155-01-05 is a Connector for industrial control and automation applications.

Bently Nevada 200155-01-05 is a low frequency Trendmaster Pro accelerometer designed for fin-fan and slow rotating shaft applications. It delivers a sensitivity of 10.2 mV/(m/s2) (100 mV/g) at 80 Hz with ±12% tolerance, making it a reliable choice for condition monitoring in demanding industrial environments.

What makes the 200155-01-05 suitable for slow-speed machinery?

The accelerometer covers a frequency range of 1.5 to 10,000 Hz (90 to 600,000 cpm) referenced to 80 Hz with ±10% tolerance. This wide range allows it to capture low-frequency vibrations typical of slow rotating shafts and fin-fan coolers. The measurement range is ±196 m/s2 (±20 g), and amplitude linearity from 1 to 10 g peak is ±2%. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), ensuring accurate data above the operating range.
