Innovative Intelligent Method for Compensating Abmient Temperature Adverse Effect on CPS Output

Abstract

Capacitive Differential Pressure Sensor (CPS) is extremely used in industries. However, CPS accuracy is limited because of the adverse effects of the ambient temperature on their output characteristic. In this paper fuzzy rules are employed to create a look-up table. The ambient temperature has adverse effects on CPS output characteristic, by using this look-up table we have access to compensated value of differential pressure 1P.
