Abstract
A sensor apparatus, such as a pressure gauge, comprises a sensor arranged to produce a sensor output signal that varies with a measured parameter such as pressure, and a plurality of output channels each arranged to receive the sensor output signal. The output channels are each optimized for a different range of the measured parameter. The apparatus further comprises an analog to digital converter (ADC) and control module arranged to select one of the output channels and connect it to the ADC so as to produce a digital channel output, and an output module configured to generate an output reading from the digital channel output of the selected channel.
