Moisture measurement inthe concrete mixer
Nowadays, the concrete quality is ofvital importance for the industrialproduction process. In order to meetthe increasing quality demands, it isessential to control and regulate themoisturecontent. The Water Batching Computer BT-7000 determines themoisture of the concrete in the mixer fast and exactly. It calculates and doses the water to be added with high repeatability and is thus the basis for a constantly optimal concrete quality.
The Tuning Curve
The distinct advantage of the Bikotronic Water Batching Control System BT-7000 is the creation of the tuning curve. Every time we enter a new recipe, the system will create automatically a recipe specific tuning curve. This ensures the highest possible accuracy for the preparation of each concrete mix. Since recipe specific tuning curves are automatically created and saved by the BT-7000, the operator does not need to edit or calibrate these curves by using complicated water/cement ratio calculations. Temperature measurement
Typically, the amount of water to be added, to achieve a specific concrete property specification is based on a normal ambient temperature of approximately 20 °C (68 °F). To maintain the desired concrete quality at above normal temperatures, the BT-7000 not only measures the moisture content of the dry concrete mix, it also measures the temperature of the dry concrete mix. Temperature deviations are recognized and the amount of water added is adjusted in accordance to a temperature curve, which is stored in the background of the programme. This feature ensures the correct moisture content in the concrete, even at elevated product temperatures.
