ABSTRACT:
During the transmission of measurement values of a sensor from a transmitter circuit to a receiver circuit, for example via an optical fibre, use has been made of a device which must be activated by the receiver circuit before a measurement value can be transmitted. This is done in order to achieve potential freedom. The novel device for transmitting the sensor measurement values aims to operate faster and independently of the receiver circuit. The sensor (1) is activated by control pulses generated by a pulse generator circuit (3) and applies to the pulse generator circuit, during the occurrence of a control pulse, a measurement pulse which is dependent on the measurement value circuit. The repetition frequency and/or the width of the control pulse then depends on the amplitude value of the measurement pulses.
