Features
PSŲ21 has the capability to measure besides strain gages also capacities. 
measuring principle is a direct derivate of the 
measuring principle. The measuring capacitor and a reference capacitor build together with a resistance an RC network. They ratio of the capacities is given through the ratio of discharge times. Patent pending algorithms provide a good suppression of parasitic capacities and ensure a very good temperature stability.
Advantage Capacitance-to-Digital Converter:
