VISCOSITY CONTROL AND CORRECTION – VISCOMETERS

G31 for the corrugated market

The G31 for the corrugated market is a microprocessor controller for the regulation of the pH, temperature and viscosity of water based ink. The viscosity measurement is made through a vibration sensor inline with the ink piping without moving parts.
This sensor emits a frequency to the controller that processes the viscosity in seconds (cup ZAHN, FORD etc.) and, then to the solvent valve, which maintains the value according to the reference signal.

The cleaning of the viscometer is made at job end, while washing up.

Applications

Corrugated and Cardboard. Flexographic and Rotogravure presses. Water based ink, varnish and lacquer.

Console and commande screen

HMI 4,3” – 7” – 9,7” touchscreen display. All colours displayed on the screen. pH, temperature and viscosity data are displayed on a graphic bar. Individual cup settings to desired reference. Save up to 50 different jobs. Error signals (no ink, no water, or pH or temperature or viscosity over tolerance).

Control G31

Rack system cabled by connectors. Installed in a cabinet. Serial communication between HMI and control.

Viscometer G31-RIV

G31-RIV Stainless steel to install in a danger zone near the ink tank. Water correction through pneumatic valve. Feeding by rotary or alternative pumps. pH, temperature and viscosity accuracy is measured within 1%.

Option

PC 15” touchscreen display. Magnetic filter G70.

Maintenance and cleaning

At the end of the job, the cleaning of sensors is made simultaneously with the press ink cleaning system. No mechanical parts or moving components.
