Third International Conference on Systems (icons 2008)
Smart Differential Pressure Sensor with Bluetooth Communication Interface
April 13-April 18
ISBN: 978-0-7695-3105-2
This paper presents design and assembly of mixed electronic circuitry for measured signal processing of the capacitive difference pressure sensor, as well as analysis of the obtained results. The smart pressure sensor provides values of measured pressure via 4 - 20 mA current loop output. The loop current is also used for sensor circuitry supplying. This means that current consumption of the whole sensor electronics should be less than 3.5 mA even in extended industrial temperature range from –40 to +125 ?C.
