A torque control is provided as overload protection and in special application cases, a function can be provided to hydraulically lift the scraper blades. By means of the measured torque, the thickening rate can be determined in order to automatically

18 Digital Potentiometer Design Guide The following circuit shows a Wheatstone Bridge with current limiting. In a Wheatstone Bridge, there are four resistive elements. In this example, two are fixed value (R1 and R2), there is a resistive sensor (RSENSOR) and then there is the digital

. The hardware shutdown forces the resistor network into a defined condition where the resistor network is disconnected from the Terminal A pin and the Wiper value is forced to 00h (Wiper connected to Terminal B). The Wiper register retains it value so that when shutdown is exited the wiper returns to it
