In this digitalized world, sensors play an important
role. These are widely used for performing the various task in every industry,
commercial or the domestic life. Traditionally, we use the socket switchboards
for controlling the operation of various appliances be it an industrial motor,
encoders, cabin air pressure, spectrometers etc.
DEFINITION
Sensors are the physical device which is used for
detecting the input (change in activities) from the real world and immediately
act according to that situation. Usually for the accident free and error free
handling of various industrial goods, various type of sensors is used. For the
fully automation of various industrial goods modern and advanced sensors is
used.
CRITERIA FOR
CHOOSING SENSORS
Since sensors are widely used in various of the
industrial goods, for the safe and accident free handling, certain features
must be considered while choosing the sensor.
·
Accuracy
·
Calibiration
·
Range
·
Cost
TYPES OF SENSORS
There are various types of sensors available for
different of the applications. These can be broadly classified on the basis of
their characteristics. One can easily find sensors of active or passive type,
digital or analog type. In electrical components, sensors are also classified
on the basis of their working principle. Different type of sensors available
are classified as
- Temperature Sensors: Commonly used for measuring the difference in environmental quantity and are of various types for different applications.
- Pressure Sensors: These type of sensors is used for measuring the variation in pressure.
- Smoke and Gas Sensors: Commonly used for detecting the leakage of gas or smoke and are used in various of industries.
- Ultrasonic Sensors: These type of sensors are normally used for measuring the distance.
Apart from these, there are numerous type of sensors
available based on various type of applications.
