<p>Fuel addition is regulated by continuous measurement of the electrical resistivity of the final product, sintered tool or intermediate product. The ferrous oxide content of the sintered product is determined by direct continuous measurement of its electrical resistivity. An electrical supply is used,pref. alternating to avoid polarisation of the brushes, which emit a signal through the sintered prod. carried on a conveyor belt.</p> |
