Tank linearization
Example:
Fig. 22: Example for tank linearization
You want to determine the amount of cereal filled into a silo, display this information on site and
transfer it to a process control system. A 4-20 mA level sensor determines the level in the
container, the connection between the level (m) and volume (m
proportional to the sensor current. The volume calculated is output as a 0-20 mA signal at the
analog output in proportion to the volume. In the event of a fault in the system, the analog
output outputs an error signal of 21.0 mA.
• Container empty:
– Sensor signal 4 mA
– Level 0 m
– Numeric display should show 0 (m
– Bar graph should show 0%
– 0 mA should be present at the analog output
• Container full:
– Sensor signal 20 mA
