Example: The congured range is 10 to 90 mils and the current gap is 30 mils.
Boom Scale Gap = 10 mils
Top Scale Gap = 90 mils
Current = 16 * (30 -10) / (90-10) ) +4mA = 8mA
NOTE: Tolerance is + 0.15 mA.
4.2.1.2 RADIAL VIBRATION
The transmier current output is linearly proporonal to the full scale vibraon range
between 4 mA and 20 mA. The following equaon represents the relaonship between the
vibraon and the loop current:
Vibraon = (Current (mA) -4) / 16 * (Full Scale Range)
