One point is determined by a moveable position magnet, whose distance from the null point corresponds to the section to be measured. The run time of an emitted impulse is directly proportionate to this section. Conversion to an analogue measuring signal takes place in the downstream electronics. The waveguide is housed in a pressure-resistant stainless steel tube or extruded profile. To the rear of this is a die-cast aluminium housing containing the electronics in SMD technology. Electrical connection is implemented via a circular connector. In the rod version, the position magnet is located in a ring, which is guided over the rod without contact. In the profile version, it is located either in a slider, which is linked to the moving part of the machine via a ball joint, or it moves as a liftable position magnet, without wear, over the profile. Standard measuring strokes: □ Up to 1000 mm in 50 mm steps □ Up to 5000 mm in 250 mm steps (profile version: MPA) □ Up to 7600 mm in 250 mm steps (rod version: MSA) TWK-ELEKTRONIK GmbH ■ PB. 10 50 63 ■ D-40041 Dusseldorf ■ Tel.: +49/211/63 20 67 ■ Fax: +49/211/63 77 05 ■ [email protected] ■
