Arrangement with several measuring devices

摘要

The invention relates to an arrangement with several measuring devices for recording physical quantities and with a central processor unit connected to the measuring devices and operating in time-division multiplex mode. To be able to carry out the data transmission reliably and in a simple manner in such an arrangement, transmitting and receiving devices (TRS, TRR) of all measuring devices (TR1...TRn) and the transmitting and the receiving device (CES, CER) of the central processor unit (CPPU) are arranged in a single circuit with an operating voltage source (E), forming a single current loop (L). <IMAGE>
