Material temperature compensation
When used in higher temperature ranges, the dielectric constant (ε
r
) of water and certain
materials being measured show a temperature dependency. Moisture is determined using
the dielectric constant, i.e. the dielectric constant is the actual parameter measured during
moisture measurement. If materials being measured, such as maize, display a very special
temperature dependency of the dielectric constant, such as a temperature dependency only
in very specific moisture ranges, it may be necessary to perform complex material
temperature compensation. This involves a considerable amount of work in the laboratory,
however. In addition to the measurement of the moisture, this also requires the
temperature of the material to be measured with the temperature sensor integrated in a
sensor. Parameters t0 to t5 can be set in each of the 15 calibration stages Cal1 to Cal15
(see the "Selecting the individual calibrations" section). If necessary, contact the
manufacturer's Service Department if you require assistance with this very complex
material-specific temperature compensation process.
