Sensors and transducers are used throughout the worlds of science, technology and industry to measure and control physical events. They range from simple devices such as thermocouples to sophisticated sensors used in aerospace applications. Most sensors output their data in an electronic form of one sort or another and it is this signal that forms the analogue of the physical quantity being monitored. But if you want to either specify a sensor or acquire meaningful data from a sensor, you first need to understand terms such as total error band, accuracy and precision, explains Mike Baker of Sherborne Sensors.
