Sensors and Measurement

The measurement and control systems present subgroup of common information systems systems for processing of information. Each system for processing of information consists of 3 basic parts: input transducer, modification unit and output transducer.
The role of input transducer in the case of the measurement and control systems is to identify the information discrabing the measurement resp. control system state and to transform them to the form suitabe for processing in the next block. Nowadays the electrical signal is preferable form input transducer (sensor) is the primary source of information about measurement resp. control systém and determines the characteristic of entire systém. In the most caces it is the most expensive part of entire systém. The aim of subject is to present basic principles used for conversion of nonelectrical quantities to electrical signal, basic properties and designs of input transducers and methods of nonelectrical quantities measurement. The abovementioned knowladges enable students select the proper sensors for implementation in measurement and control systems.
