EPLC is an absolute linear potentiometer transducer without internal rod. This transducer is characterized by a cursor with integrated coupling sliding on the axis. This system eliminates problems due to air compression generated from the insertion of the rod and longer strokes are reached. The main characteristic is the absence of variations on the electrical output signal outside of the theoretical electrical stroke. This transducer is also suitable for being used in explosive environment or in presence of gas or infl ammable powders.
