The potentiometer is a sensor generally used to detect angles. As shown in the diagram,
it is configured similar to a volume control (a variable resistor). Here, a brush moves while
in contact with a resistive element, and the electrical potential changes according to the brush
location. We use a conductive plastics element for improving precision, resolution, and durability
characteristics, and the resistive element is trimmed to improve its linearity characteristics.
At manufacture, each item of data of every potentiometer is measured, one by
one, and table data is created and written accordingly. The aims here are
increased precision and reductions in trimming work (a patent has been
obtained for this technology).
This sensor was developed with support funds from the gTechnical Creation Support Funding Programh
of Niigata Prefecture.
