MEASURING PRINCIPLE
RINGBALANCE AS PRESSURE GAUGE
MEASURING PRINCIPLE
This is how the rixen-ringbalance works
FUNCTIONALITY
A hollow ring, freely rotating on bearings and half filled with liquid, is divided into two chambers by a partition “A”.
Positive and negative or differential pressures are applied to the chambers of the ring body through flexible tubes “S”.
The pressure differential across partition “A” causes the ring body to rotate until it is in equilibrium with the counterweight “G”.
LONG-TERM-ACCURACY
The calibration of a Ringbalance is entirely determined by the mass of the counterweight “G”.
A weight cannot “age” or become “overloaded”.
THE FILLING FLUID
Since the differential pressure is ultimately balanced by the counterweight “G”, it follows that neither the quantity nor the density of the filling fluid play a role in the actual measurement or in the Ringbalance-Equation.
