Description

The capacitive measuring systems of the TRUELeVeL® series are designed for analogue level measurement. The system consists of a level probe and evaluation electronics. The analogue level measurement automatically compensates for the DK change (DK = dielectric constant) of the product to be measured. This is particularly advantageous for level measurements with changing media. For the DK compensation a “reference” measurement is carried out, for this purpose there is a reference range in the probe tip.

The TRUELeVeL® probes are available in customised lengths from 400 mm to 2000 mm. The position and length of the measuring section can be freely defined within the possible measuring range and can thus be optimally determined for the respective application. There are different variants of the evaluation electronics, from analogue output voltage 0…10 V DC via current 4…20 mA up to frequency 0…10 kHz. The setting of the measurement is very simple and can be carried out completely in the empty state. The direction of action of the output signals as well as the LED display can be defined by dip switches. Sloshing movements can be faded out by an adjustable time delay (attenuator). A relay assigned to the reference section can be used as no-load protection.

Advantages are:

– Level measurements in containers, pipes up to approx. 5 m diameter.
– For liquids and bulk solids εr ≥ 1.2
– Also suitable for inhomogeneous media due to large measuring volume detection
– With appropriate mounting almost independent of the cone of repose
– Probe can be used in the range from – 70 °C to + 250 °C
– Insensitive to electrostatics
– Automatic compensation of dielectric constants means it can also be used with changing materials without recalibration
– Complete adjustment can be easily carried out in empty condition
