VIM3*-IO-* Vibration Sensors
Process Data Structure
7 Process Data Structure
Four different measured variables are transmitted as process data by the VIM3*-IO-* vibration
sensor. These are each transmitted as a Measurement Data Channel (MDC) 1 ... 4. These are
Velocity RMS, Vibration Acceleration RMS, Vibration Acceleration Peak, and Temperature. The
figure below illustrates the process data structure:
Figure 7.1
Two independent adjustable switching signals (SSC) are transmitted for each measured vari-
able. In addition, adjustable thresholds and data allow a plant maintenance cycle to be defined
on the device. The "Maintenance request" switching information displays whether a plant main-
tenance cycle is necessary.
