Szenzortípus

Szenzortípus refers to the classification or category of a sensor based on its operating principle, the physical phenomenon it measures, or its intended application. Understanding sensor types is crucial for selecting the appropriate device for a given task, as different types exhibit varying sensitivities, accuracies, response times, and operating conditions.

Common sensor types can be broadly categorized. For example, based on the physical principle, one might encounter resistive sensors (where resistance changes with a physical property), capacitive sensors (where capacitance changes), inductive sensors (where inductance changes), and piezoelectric sensors (which generate a voltage under mechanical stress). Another classification is based on the measured quantity, such as temperature sensors (thermocouples, thermistors, RTDs), pressure sensors, light sensors (photodiodes, photoresistors), motion sensors (PIR, ultrasonic), and chemical sensors.

In industrial automation and research, a detailed understanding of sensor types is essential for system design, calibration, and troubleshooting. The choice of sensor type directly impacts the reliability and performance of data acquisition and control systems. Furthermore, advancements in sensor technology continuously lead to the development of new and specialized sensor types designed for increasingly complex measurement needs.
