Classification of Sensor

Sensors might be categorized in two types:

1. Discrete and

2. Continuous.

Discrete event sensors utilized in the manufacturing are typically depend on mechanical, electrical, or optical technology.

A continuous sensor measures the magnitude of an attribute of interest of the physical procedure that is being monitored. These sensors might be utilized in measuring the temperature of heat-treating process, the pH in a chemical procedure, or the speed of a conveyor line. They provide the information over a continuous range of operation of the procedure and they are commonly utilized in continuous control applications, where the procedure is being regulated depends on continuously sensed attribute data.
