Automatic Viscosity controls for inks and varnishes

VISCOS FB 9000 is a new electronic viscosimeter for measuring and regulating the inks in printing presses. The working principle which reflects the dropping body principle guarantees high precision in measurements. The viscosimeters are constructed with the maximun level of protection, complying to the Intrinsic Security Eexi. The dropping body is pushed to the top level by the flow of the ink pump. One valve block this flow and the body is dropping down. The sensors measure the dropping time. This time is proportional to the viscosity so it can be visualized a viscosity value measured in seconds of Ford-4 cup (or Zahn-2).



Viscos FB 9000 has two operation way. In manual mode the system displays the maesured viscosity. The front panel keyboard is used to correct the error by adding new solvent. In automatic mode the system executes a comparison between the programmed viscosity and the measured one. Based on the magnitude of the difference new solvent is added to correct the error. In case of malfuction or lack of solvent the system activates (error signals) visual and sound to alert the operator. The system is designed to be auto-cleaning. The solvent enters directly to the measuring pipes during the regulation, or when activating the cleaning function at the end of the job.
