Document Type and Number:
Japanese Patent JP2540350
Kind Code:
B2
Abstract:
A drying balance with a radiation source (11) for heating and drying a substance distributed on a balance scale (5), with a temperature sensor (8) for monitoring and controlling the output of the radiation source (11) and with electronic evaluating circuitry (33) for evaluating the measured values of the balance and for controlling the drying balance that a temperature gauging disk (14) with another temperature sensor built in be used in order to determine in a temperature gauging cycle the deviation of the output signal of the temperature sensor (8) from the output signal of the other temperature sensor built into the temperature gauging disk (14) and to calculate a correction factor from them and to store this correction factor. Then, the output signal of the temperature sensor (8) is multiplied by this correction factor during dryings in order to obtain the true temperature of the substance. Different coefficients of absorption of different substances can be mimiced by surfaces on the temperature gauging disk which exhibit different sizes and a high absorption capacity or a low absorption capacity.
