Sensors act as a bridge connecting physical environment variables with electrical / electronic devices. There are many uses in industrial processes such as control, protection and imaging. Currently there are hundreds of types and different types of sensors used in the market. Due to the rapid developments in electronic technology, different new sensors or new types for them are being developed every day in this field.
We can also call sensors the sensory organs of autonomous control systems. Just as people or animals perceive what is happening around them, values such as temperature, pressure, speed etc. are transmitted to the relevant units through sensors.
It perceives and interprets the variables around a vehicle or an automation system, and completes the operations according to this data. Different types of secreters are required to detect different variables.
Variables Obtained by Sensors
Mechanic: Length, area, quantity, mass, force, torque, pressure, velocity, acceleration, position, sound wavelength and intensity.
Thermal: Temperature, heat flow.
Electrical: Voltage, current, resistance, inductance, capacitance, dielectric coefficient, polarization, electric field and frequency
Magnetic: Field density, flux density, magnetic moment, permeability.
Radiance: Density, wavelength, polarization, phase, reflection, transmission.
Chemical: Condensation, content, oxidation/reduction, reaction rate, pH.
