发明名称 TRANSMITTING/CONVERTING SYSTEM FOR INDUSTRIAL MEASUREMENTS
摘要 <p>The invention concerns a system for acquiring and processing measurements of physical quantities, consisting of a central measuring unit (1) and input (2) and output (3) modules, external to the central unit (1), having links with said central unit for communicating therewith for data transfer. The invention is characterised in that the system comprises means for communicating by optical radiation, in particular infrared (28 to 31), without physical contact, between the central unit (1) and the input and output modules (2, 3). The invention is useful for measuring electrical magnitude and other physical quantities such as temperature or pressure.</p>
