VISCOSITY CONTROL AND CORRECTION – VISCOMETERS

Viscometer G20

The G20 is a microprocessor controller for the regulation of the viscosity of solvent 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

Rotogravure and Flexographic presses. Solvent based ink and varnish.

Console and command screen

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

Control G20

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

Viscometer G20-RIV

G20-RIV to install in a danger zone near the ink tank. Solvent correction through pneumatic valve. Feeding by rotary or alternative pumps. Viscosity accuracy is measured within 1%.

Option

Control temperature by G90 heat exchanger. PC 15” touchscreen display. Magnetic filter G70.

Maintance 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.
