Bently Nevada 990-08-xx-03-00 | 0-8 mils Range

Engineering Purpose

The 990-08-XX-03-00 is a 2-wire, loop-powered vibration transmitter designed to simplify machinery protection. It integrates Proximitor sensor technology and signal conditioning into a single unit, providing a 4-20 mA output proportional to radial vibration. With a 0-8 mils full-scale range, it is an ideal solution for monitoring the health of rotating machinery such as pumps, motors, and fans in diverse industrial environments.
