Bently Nevada 991-06-50-01-CN | 2-Wire Thrust Transmitter

Engineering Purpose

The 991-06-50-01-CN is a loop-powered transmitter specifically calibrated for axial position (thrust) monitoring. It converts the displacement signal from a 3300 NSv probe into a 4-20 mA output, allowing direct tracking of shaft movement relative to the thrust bearing. This model is certified for the Chinese market and is essential for preventing internal machine contact in turbines and pumps.
