Device for determination of the position of a jack piston using a linear potentiometer has connecting wires to the potentiometer with improved routing and simplified connection means to simplify jack construction

摘要

Jack includes a linear potentiometer with a connection (3) that connects it to a meter positioned in the bottom (11) of the jack. The connections to the meter ensure that the sensor (20) angular and longitudinal positions are maintained as is the water-tightness of the jack and sensor.
