Positioning arrangement for a measuring-value sensor

摘要

The invention relates to a positioning arrangement for a measuring-value sensor, which is secured to one end of a guide tube. The other end of the guide tube is connected to a fixedly arranged screw device serving for the longitudinal displacement of the guide tube. A lead connected to the measuring-value sensor extends through the guide tube to an evaluation unit. The longitudinally displaceable guide tube provided with an internal thread is unrotatably arranged and the screw device has a stationary adjustment screw rotatably arranged in the internal thread of the guide tube.
