Device to determine absolute moisture content of concrete in container; has measuring probe to determine moisture content or temperature of concrete and to transmit signal by wireless method

摘要

The device has at least one measuring probe (4,5) to determine the moisture content or the temperature of the concrete. The probe signal is transmitted by a wireless method. The probe has a detector or transmitter to transmit the signal to an evaluation unit. Preferably, the probe is powered by an accumulator. The absolute moisture content is determined at regular time intervals and an average value is calculated.
