Accuracy advantage of a digital sensor over an analog sensor

What is the accuracy advantage of a digital sensor over an analog sensor?

The advantage of a digital sensor over an analog sensor comes from the fact that an analog to digital converter isn't required. The digital sensor signal can be fed directly to the transmitter's CPU without any additional signal processing.

The DPharp sensor produces two frequency outputs which are proportional to the applied pressure to the sensor. The frequencies are then simply counted by the CPU to determine the pressure.
