Selection criteria and requirements of sensor or transducer
The following are certain features that are considered when choosing a sensor. Type of Sensing: The parameter that is being sensed like temperature or pressure. Operating Principle: The principle of operation of the sensor. Power Consumption: The power consumed by the sensor will play an important role in defining the total power of the system. Accuracy: The accuracy of the sensor is a key factor in selecting a sensor. Environmental Conditions: The conditions in which the sensor is being used will be a factor in choosing the quality of a sensor. Cost: Depending on the cost of application, a low-cost sensor or high-cost sensor can be used. Resolution and Range: The smallest value that can be sensed and the limit of measurement are important. Calibration and Repeatability: Change of values with time and ability to repeat measurements under similar conditions. Basic Requirements of a Sensor or Transducer The basic requirements of a sensor are: Range: It indicates the limits of the input i...
