The ANGUSENS inclinometers generally sense and measure the angle of tilt (Inclination/Slope/Elevation) of an object, with respect to the relative change in electrical conductivity.
Measurement Setup
It consists of two identical Platinum electrodes deposited in pairs on the base of the sensor’s cell. The chamber of the sensor’s cell is partially filled with an electrolytic liquid and placed parallel to the sensitive axis of measurement.
Measurement Principle
When alternating voltage is applied to the electrodes, the electric current will create an electric field. At the parallel position both the electrodes will measure the same field. By tilting the sensor, the liquid level is not parallel anymore; it is less at one electrode and more at the other. The electric field is confined to the liquid level and because of the constant specific conductivity of the electrolyte a variation of conductivity is formed. The more the electrolyte liquid level higher is its conductivity. For example, in the figure given below the liquid level at electrode 2 is more than that of electrode 1. Hence the conductivity at electrode 2 is greater. The relative difference in conductivity between the electrodes corresponds to a particular angle of inclination on a pre-calibrated scale. To achieve highest accuracies the measurement is carried out as a differential measurement.
