The 990-04-50-01-00 Bently Nevada 990 Vibration Transmitter is designed for direct interface with a 3300 NSv proximity probe and extension cable, converting mechanical vibration into a proportional 4–20 mA output for process control and protection systems. Its compact design allows efficient installation on DIN rail assemblies and ensures dependable operation in continuous-monitoring environments.
Configured for a 0–4 mils peak-to-peak full-scale vibration range (equivalent to 0–100 µm)
Supports 5.0 m system length, compatible with NSv proximity probe assemblies
DIN-rail mounting clips included for fast, secure installation
Operates from a +12 to +35 VDC power source for flexible panel integration
Suitable for monitoring small-diameter shafts or lightly loaded rotating equipment
Provides a stable 4–20 mA output proportional to vibration amplitude
