Sensor

Introduction oblige demodulators - Motorola A sensor is a trick that produces a measured response to a change in a physical characterise, such as temperature or thermal conductivity, or to a change in chemical concentration. Sensors be snap officularly useful for making in-situ measurements such as in industrial process control. Sensors be an important dissociate to any measurement and automation application. The sensor is responsible for converting or so type of physical phenomenon into a quantity measurable by a data acquisition (DAQ) system. ________________________________________ Choosing a Sensor Factors to conceptualise when choosing a sensor. ?Accuracy - The statistical variant just about the engage reading. ?Calibration - Required for most measuring systems since their readings go away tramp over time. ?Cost ?Environmental - Sensors typically keep back temperature and/or humidness limits. ?Range - Limits of measurement or the senso r. ?Repeatability - The variance in a sensors reading when a single condition is repeatedly measured. ?Resolution - The smoothest increment the sensor can detect. ________________________________________ Types of Sensors Sensors are use to measure basic physical phenomena including: 1. acceleration - puff & Vibration. 2.angulate / Linear Position 3.Chemical/Gas Concentration 4. humidity 5.Flow Rate 6.Force 7.Magnetic Fields 8.Pressure 9.Proximity - Spatial Presence 10.Sound 11.Temperature 12.Velocity 13.Sensors: Acceleration 14.________________________________________ 15.Acceleration Accelerometers 16.An accelerometer is an electromechanical transducer which produces at its output terminals, a potency or placard that is proportional to the acceleration to which it is subjected. The piezoelectric elements (similar to small crystals) within the accelerometer turn over the property of producing an electrical charge which is without dela y proportional to the configuration and thu! s the applied...If you want to get a full essay, modulate it on our website: BestEssayCheap.com
