Analyte automation supplies various products of gefran, italy as their sole distributors for india. In machine automation measuring stroke or linear motion is one of the most critical aspects, considering complex mechanical arrangements involved and accuracy required. The company claims that this linear potentiometer to be the simplest and cheapest solutions. These linear potentiometers have a layer of conductive plastic on the pcb and wipers move over them to provide signal proportional to wiper position. The gefran linear potentiometer provides 0.05% linearity and more than 100 x 106 operations life and has an advantage over rotary encoder that it gives absolute measurement value. The linear potentiometer unlike encoder does not have to do referencing of the machine in case when power goes and restores back. This linear potentiometers are applied for measuring and controlling, clamping/injection strokes, dancer roller position monitoring and controlling, controlling tension on film, hydraulic press jaw control, etc. The company also supplies gefran magneto restrictive sensors for higher life cycles and higher accuracy with an infinite life.
