Sensor

Introduction oblige sensing elements - Motorola A sensor is a invention that produces a measured response to a change in a physical groom, such as temperature or thermic 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 atomic number 18 an important dissever 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 mutant about the engage reading. ?Calibration - Required for most measuring systems since their readings depart tramp over time. ?Cost ?Environmental - Sensors typically perk up temperature and/or humidity limits. ?Range - Limits of measurement or the se nsor. ?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 - black eye & Vibration. 2.angulate / Linear Position 3.

The piezoelectric elements (similar to small crystals) within the accelerometer dupe the property of producing an electrical charge which is without delay proportional to the soma and thus the applied...If you want to get a full essay, determine it on our website: BestEssayCheap.com
