continuous surveillance vibration transmitter
Condition Monitoring and Protection
for continuous surveillance
The 990 Vibration Transmitter is used for centrifugal air compressors with fluid-film bearings. The transmitter's 4-20mA signal output is proportional to the vibration levels of machinery being monitored. While this signal is primarily used for trending, using the 999 test adapter allows viewing of actual waveform of the actual vibration.
