Sensors used in the manufacturing industry monitor the performance of various processes and aspects of machine operation, collecting data to determine normal baseline levels of operation while also detecting even the most minuscule fluctuations in that performance.
Sensor/Detectors/Transducers are electronic or electrical devices. These special electronic sensitive materials sense, measure, and detect changes in the position, temperature, displacement, electrical current, and multiple parameters of industrial equipment.
different types include hygrometers and moisture meters (for measuring moisture), gyroscopes (for measuring rotation), current or voltage sensors, pressure sensors, position sensors, level sensors and flow sensors (for fluid management).
role of a sensor in a control and automation system is to detect and measure some physical effect, providing this information to the control system
main performance criteria for industrial sensors are sensitivity, resolution, compactness, long-term stability, thermal drift and power efficiency
