Abstract

The length measurement device has a rule adjustable w.r.t. a detector scanning the rule and producing electrical signals corresp. to the measured length. The signals are evaluated by an electronic circuit. It gives accurate error-free length measurements and has a simple reliable compact construction. The rule (1) contains a marking carrier magnetised at defined intervals to form readable markings sensed by the detector reading head. The sliding part (2) which carries the detector also contains the processing circuit in an electronic chip and an associated battery power source. The electronic circuit has on-off (7) and null condition setting (8) switches. Further processing units may be connected to the rule via a plug connector (9), e.g. for digital indication.
