Abstract: Industrial applications such as air-conditioning, microelectronic, automotive, food processing are automated using various sensor technologies. The sensor technologies could be temperature, pressure and others as well. The negative temperature coefficient (NTC) sensors are the preferred choice due to their stability over their counterpart positive temperature coefficient (PTC) sensors. These sensors are highly nonlinear and need special signal conditioning circuits to use them in all industrial applications. Pressure sensor does need a special treatment while measuring their values for industrial applications. This paper presents the method to model, characterize and linearize NTC and pressure sensors. A low-cost system was built to validate the presented method.
Keywords: Temperature, NTC/PTC, Coefficient, Modeling, Characterization, Linearization, Pressure Sensor.
