ABSTRACT:
A system for the automatic identification of the type of measuring head (1) of a fiber optic measurement value acquisition and transmission device which exhibits a measurement signal fiber (3) and a control signal fiber (4), in which the measuring head (1) can be remotely operated from a control unit (2) by means of control signals which are transmitted via the control signal fiber and, in particular, can be caused to emit a calibration signal. According to the invention, calibration signals of different frequencies are provided for various types of measuring heads. Using the frequency of the calibration signal, the control device is capable of identifying in each case the measuring head connected to it.
