3. PRINCIPAL OF SERVO MEASUREMENT
Principle of Measurement
Figure 4 Principle of Measurement
The principle is based on detection of variations in the buoyancy of a displacer. The
displacer is suspended from a strong, flexible measuring wire which is stored on a
precisely grooved measuring drum.
The shaft of the drum is connected to the stepper motor via a magnetic coupling.
The apparent weight of the displacer is measured by a force transducer. The actual output
of the force transducer is compared with a desired value for the apparent weight of the
displacer. If a discrepancy exists between measured and desired value, an advanced
software control module adjusts the position of the stepper motor.
