The new S6-VR ultrasonic viscosity control system from Fasnacht Switzerland is designed for the printing and coating industry. Its sensors are maintenance-free, durable and can be used on all printing equipment. Whether it is a printing equipment or coating equipment using gravure printing or flexographic printing technology, the S6-VR ultrasonic viscosity sensor can quickly measure the viscosity value and temperature to improve the performance of the equipment. The viscosity control system can control the viscosity value of water-based or solvent-based inks during the printing process. Fasnacht's new S6-FB falling ball viscosity control system is highly accurate and economical. It can be used in gravure and flexographic printing to control the viscosity and temperature of water-based or solvent-based inks, adhesives, 2K paints, and coatings. The new viscosity control unit adds new functions. The viscosity measurement is measured from the bypass of the ink supply line.
