Description: Sensors (detectors, probes) are used to measure and monitor the parameters of technical systems. Sensor elements are usually switching systems that register chemical, physical or Material variables such as acceleration, temperature, pressure, brightness or material environmental properties via physical effects. A sensor will use inductive, piezoelectric, magnetic, field-Strength controlled or photoelectric transducers to convert the detected parameters into electrical signals (unified signals, fieldbuses) that can be interpreted and processed. A distinction is made between mechanical and non-mechanical sensor elements. Mechanical sensor elements include: Force sensors such as weighing cells, pin sensors, load cells and force transducers Positional and proximity sensors (such as strain gauges) Non-mechanical sensor elements include radiation detectors for: Temperature (thermocouples, RTD element) Light (photo sensors) Sensors are used in process control and Automation technology, in safety systems and in many other applications. They can be wireless or wired. When equipped with their own microprocessors, they are referred to as smart sensors.
