Humidity meter with controllable drying device and continuous measurement processing

摘要

Humidity meter comprising a balance (1) for weighing the product to be measured (2), which is dried by an energy radiator (3). The humidity meter has an evaluation device (MP) for the weight measurement signal (G(t)) and a control circuit (PS), connected thereto, for controlling the energy supply to the product to be measured (2). The control is carried out by modifying the current flow (JL) to the energy radiator (3) or by means of a positioning device (Pv) for the energy radiator (3). The control circuit (PS) for the control device may be extended with the radiation sensor (Ph). The method carried out in the evaluation device (MP) makes it possible to complete the measurement in an optimum time with a specified accuracy. <IMAGE>
