ABSTRACT:
An arrangement for displacing a measuring head of a measuring device into and from a process space. The arrangement comprises a valve element and a measuring device. The measuring device comprises a tube, at one end of which there is a measuring head. The measuring device is arranged to be moved through the valve element to a position in which the measuring head extends into the process space and again to a position in which the measuring head is not in connection with the process space. To effect a controlled displacement of the measuring device, the arrangement comprises two threaded bars parallel to the displacement direction of the measuring device and fastened to the valve element as well as two threaded stop elements arranged in the measuring device. The motion for the displacement of the measuring device has been arranged to be effected by relative motion between the stop elements and the threaded bars.
