Potentiometer for displacement detection has measuring resistance with resistance strip corresponding in length to maximum displacement

摘要

The potentiometer (1) has a measuring resistance, a voltage source (3), a displacement dependent voltage tap-off (4) and a measuring device (5), with a flat screening housing (9) attached above or below the displaced component, provided with an opening for a flat plastics tongue (11). The housing and the plastics tongue are associated respectively with the resistance strip and the voltage tap-off, the length of the resistance strip and the tongue movement corresponding to the maximum displacement path.
