Conventional Rotational Sensor
The conventional sensor has a brushless drive motor. The explosion-proof sensor placed in the liquid measures the rotational resistance. When the viscosity increases, then so does the liquid resistance, which will affect the speed of the revolutions of the rotating cylinder (pick-up device). When the viscosity goes beyond the limiting values (readable on the touch screen), the solenoid valve opens automatically and solvent/water will be added to the ink, until the pre-set viscosity is reached. Recently a very sensitive measuring device has been developed, providing even better measurement accuracy. The system is easy to clean and therefore simple to use.
