O-FRAME INSTRUMENTATION

DESCRIPTION

Basis weight, moisture and caliper are the three most important quality parameters to be monitored to produce quality paper as well as conserve energy, raw materials and increase productivity.

The INDSCAN system enables the paper machine operator to monitor all the above mentioned quality parameters continuously on-line, in real-time, with appropriate automatic control of Basis Weight and moisture in the machine direction.
This is useful for the industries like pulp paper, aluminium, plywood, plastics, textiles, etc.
