The integrated DT-120 series displacement transmitters are based on the non-contacting eddy current measurement principle, which has proven itself in the machine monitoring sector for several decades. It allows the distance between the tip of the displacement transmitter and an electrically conductive surface to be measured. The integrated electronics measure the axial shaft position or the radial shaft vibration from the displacement signal, depending on the model being used. The measurement result is outputted to a subsequent controller, via the loop-powered interface, as a 4 - 20 mA signal. An additional dynamic output provides a diagnostic signal for simple system setup or signal analysis. Our series DT-120 eddy current displacement transmitters are distinguished by their innovative design. All of the measuring electronics and the loop-powered interface are integrated in the transmitter's housing. This considerably simplifies the installation of these systems as compared to those with external driver electronics. The displacement transmitter is available in both forward and reverse mount versions.
