Continuous panel weight measurement

CONTI-SCALE measures the board weight continuously and very precise – also in “endless production” (without gaps between panels).

Because the measurement is non-contact the tare weight of the conveying system has no influence to the measurement accuracy which is the case in mechanical scale systems. Also high speed and vibrations have no negative effect.

CONTI-SCALE consists out of several measuring tracks which are located crosswise to production. This allows evaluating the distribution of the weight per unit area lengthwise and crosswise. Taking the known board dimensions (length x width) into consideration the weight will be shown. If in addition the board thickness also is fed in the system the distribution of the density can be displayed.

Is this an isotopic smoke detector?
This question could be raised by local acceptance authorities, which have been asked to approve the handling of the CONTI-SCALE. The designation 35MBq (1mCi) equates to the radiation of an isotopic smoke detector. In comparison: Weight-per-Unit-Area Gauges (used in earlier times) located before the press employed Americium sources of 100mCi. The radiation level of the CONTI-SCALE is just 1/100th of that figure. It can, therefore, be concluded that an exposure problem doesn’t exist. The advantages of using an Americium source are considerable. The high stability of the low-energy isotopic measuring radiation results in high accuracy. No other supplier of measuring technology can offer this today.
Furthermore: The cost to the plant to install equipment of this high technical level is very reasonable and available at a very competitive price.
