Bently Nevada 990-08-XX-01-00 Vibration Transmitter

Engineering Purpose

The 990-08-XX-01-00 is a 2-wire, loop-powered vibration transmitter designed for robust machinery monitoring. It integrates the functionality of a proximitor and a signal conditioner, providing a 4-20 mA output proportional to radial vibration. This model is specifically scaled for a 0-8 mils range, making it suitable for larger vibration envelopes typically found in motors, pumps, and mid-sized turbines.
