Description
The primary purpose of the Dynamic Input module is to digitize the sensor signal at
a rate that completely encompasses the signal content and provides transducer power for various sensors.
The Orbit 60 Series Dynamic Input modules are a set of 4-channel input modules available
in both negative and positive dynamic input options. The inputs are also used for speed
or Keyphasor signals All dynamic input modules that support speed or Keyphasor signals
can be configured to have Primary and Backup Speed Source support,
to allow for speed redundancy functionality.
The module supports backup speed source functionality.
When configured, if the primary speed source enters an invalid state,
a backup speed channel will be utilized to provide a speed reference for
configured synchronous measurements. Compensations for differences in shaft
speed and phase reference timings can be configured to maintain measurement
accuracy upon transitioning to backup speed sources.
The Orbit 60 dynamic input modules are designed for use on a broad range of machine
trains or individual casings where the sensor point count fits the monitor’s channel
count and where advanced signal processing is desired.
The modules are optimized for intensive signal processing required on complex
machinery such as gearboxes, planetary gearboxes, reciprocating compressors,
and roller element bearing (REB) machines, as well as offering advanced measurement
capabilities on conventional monitoring methods such as radial vibration,
thrust position, piston rod monitoring, and casing absolute vibration.
