The mechanical detection of linear movement is done by a front guided or loose push rod.
Available are versions as a probe (RACT) with inner spring return device, with a guided push rod (RACC) on which ball joints can be mounted and with a loose push rod (RACL). All types are supplied with an AC voltage and provide an AC voltage output that is corresponding to the displacement of the core.
The inductive measurement principle of the RAC is configured in LVDT winding. Due to the contactless measurement principle long lifespan can be reached and permits high dynamic application, especially if small oscillating movement has to be detected.
