Abstract

Improvements in the potentiometric depression sensors, characterized in that the sensor is made up of a depression capsule fixed on the outside of a box and provided with an elastic membrane requested by the motor depression, which acts in opposition to an adjustable spring and which it sends a stem fixed in the center of said membrane, a stem attached to one of the ends of a lever that is pivotally mounted on a shaft integral with a support and whose other end has an adjustable mounted slider, which has a susceptible wiper of being able to move along a track of a potentiometer fixed in the support so that the displacement of the stem as a function of the depression causes the displacement of the cursor and consequently a variation of the voltage yielded by said potentiometer between two limit voltages.
