Abstract: The invention relates to measured value transmitting devices for serially transmitting data in accordance with the SSI method, Synchronous Serial Interface. At least one slave is provided which provides the data bits of a measured value detected by at least one sensor for the purpose of a serial bit-by-bit transmission to a master. The master requests a measured value from the slave by means of a clock burst that has multiple clock cycles, the number of which matches the number of the data bits to be transmitted. A first measured value transmitting device according to the invention is characterized in that the clock cycles of the clock burst have a specified duty cycle which corresponds to the ratio of the pulse duration to the period duration of one clock cycle, and the master contains a comparator. The master reads the clock bursts outputted on the at least one clock line and checks the duty cycle in the comparator to determine whether an upper threshold and/or a lower threshold has been exceeded.
