VISCOSITY CONTROL SYSTEM
FOR INKS, GLUES AND VARNISHES

The SELEVISCO 9000 viscosity control system has been specifically engineered for controlling flexographic and rotogravure inks, varnishes as well as many adhesives.

The SELEVISCO 9000 systems measure and correct fluids viscosity. The system operates through a measuring head placed in line with the flow, a control panel for the display and regulation of the rheological characteristics, and, additionally, multiple accessories which complete the system’s operativity.

Thanks to a precise comparative logic, the programmed viscosity value and the measured one are compared and the diluent quantity necessary to fix the error is added automatically. It is also possible to perform a manual measuring by receiving the viscosity value directly from the system.

  • The SELEVISCO 9000 viscosity control system can control an ample spectrum of fluids, from ink and varnishes to more viscous substances such as glues and adhesives.
  • The viscosity controller ensures an elevated measuring accuracy.
  • Can be personalized and adjusted based on your needs.
  • Able to read the viscosity value even while the fluids are in motion.
  • Complete with a temperature control to correct the temperature according to its variation.
  • Requires minimum maintenance.
  • Can be integrated in a system for the management of automatic washing cycles.
  • The viscometer is versatile and can be installed in line with the fluid to be measured, or offline, inside tanks or containers.

The SELEVISCO control systems allow fluids viscosity measurement through a vibrating sensorial system immersed into the fluid that needs to be monitored.
The measuring head is protected by a very resistant capsule of small dimensions, integrating proper anchoring arrangements to external supports that allow its application easily even in extremely limited spaces. The application is normally recommended between the pumping system and the doctor blade chamber or the ink trays, interposing the head along their connection pipeline.

Through a precise comparative viscosity controller, the system enables the consistency of different fluids mixture; therefore, this type of application can be integrated and personalized in various industrial sectors.

The viscometer SELEVISCO series 9000 has been specifically engineered to control flexographic and rotogravure inks and offers the following features:

  • Wide range of application, this specific model is designed for viscosity verification within a field of 40 to 500 cps (corresponding approximately to 9 – 120 seconds using a Ford cup size 4) and therefore permits the control of inks, varnishes as well as many adhesives.
  • Extremely high precision, granting an outstanding reading tolerance with the possibility of modulating according to specific needs through personalized modes. The peculiar application allows the control of liquids in flowing conditions, thus permitting its application directly on the supplying pipeline (i.e. between the supplying pumps and the inking or coating application heads). The system sports an integrated temperature control for data modulation based on its variation.
  • Minimum maintenance, the absence of moving elements eliminates the necessity of frequent maintenance. Furthermore, SELEVISCO can be integrated with a system of automatic washing cycles, guaranteeing efficiency and functionality for extremely long periods of time without any special arrangement.
  • The operating principle of the viscosity system is adaptable to multiple solutions. The main versions provide for the inline installation on the flow meant to be measured, or offline within containers. Both solutions are based on the patented principle of the vibrating reed and guarantee extremely high precision and reliability.
Installation of the
inline vibrating sensor

The measuring head is protected by an extremely resistant capsule of small dimensions, integrating proper anchoring arrangements in limited spaces. The application is normally suggested between the pumping system and the chamber doctor blade or the ink tray.

Installation of the
offline vibrating sensor

Based on the vibrating technology, the offline sensor is installed directly into the tank, granting a better ease of use. The offline sensor is easy to clean and resistant to chemical corrosion thanks to its Teflon coating protection.

Operator friendly

The managing software allows data recording on recipes, allowing for setup and operational reputability. The data displaying and the controls are incorporated into the individual synoptics for each measuring unit. Alternatively, the measuring head can be connected to the touch screen operational interface, based on a Windows platform.

Download Brochure Selevisco9000 Control Panels

The SELEVISCO 9000 control panel allows the display of data and command execution.
Each control panel manages a unit of measurement and can be applied within existing frameworks or supplied integrated into custom pulpits.
In manual mode the system displays the viscosity measured by a single sensor and allows the operator to add the solvent to correct the viscosity value.
In automatic mode the system compares the programmed viscosity value and the measured one. Based on the magnitude of this difference new solvent is added to correct the error. In case of malfunctioning or lack of solvent the system activates the proper visual and audible alarm to alert the operator.

The system has been designed to be auto-cleaning. The solvent enters directly in the measuring sensor both during the regulation step and when the cleaning function is activated at the end of the job. Adequate liquids should be used for the washing cycles according to the fluids’ mixture (normally the solvent is used as a thinner for the ink).
The supply should be connected directly to an inlet port located on the measuring head. The data displaying and the controls are incorporated into individual synoptics for each measuring unit that can be retrofitted into existing cubicles or integrated on personalized consoles.

Alternatively, the measuring heads can be linked and interfaced to the machineries’ control systems through customized arrangements, or to PC systems with touch screen interface based on Windows operating systems, and complete with a specific software for job statistics.
The measuring heads and the control units are connected by electric wires, thus permitting the installation of these elements even within long distances.
