The widespread modernization of technological processes, and in particular the highly efficient control of various industrial plants and machines, involves constant measurements of physical quantities. This task can be handled by special devices – sensors.

Sensor Assignment

In another way, sensors are also commonly called measuring transducers. When using them, it becomes possible to obtain data on the parameters of the controlled object.

It is designed to convert various monitored quantities into a signal that will be convenient for further use, transmission, storage, processing, and in some cases for influencing mechanical processes.

Varieties of sensors

Depending on the type of the initial value, it is divided into the following types:

• Displacement sensors
• Pneumatic sensors;
• Flow meters;
• Speed sensors;
• Force sensors;
• Temperature sensors;
• Pressure detectors.

By the type of output value, which is obtained as a result of converting the initial value, it is divided into 2 categories:

• Electric;
• Non-electric.

Electric sensors are very popular, due to their obvious advantages:

• Electrical quantities are transmitted as quickly as possible over distances. In addition, they are considered universal, because all other quantities are converted to electrical or vice versa.
• Devices of this type give accurate measurement results in the form of a digital code.

Sensor Principle: Classification

According to the principle of functioning, it is divided into main groups:

• Optical Typically, these devices are compact in size, which allows them to be used in hard to reach places. Detectors operate under the influence of electromagnetic radiation in the visible infrared or ultraviolet range. They react to transparent and translucent objects, and in particular to smoke, aerosols, steam.
• Inductive. These are devices that measure non-contact. Their main feature is sensitivity only to metal objects.
• Capacitive. These are parametric converters with a non-contact principle of operation, in which changes in the measured values ​​are converted into changes in the capacitance of the capacitor. They have spread where it is necessary to control the appearance of weakly conducting liquids.
