Sensor package for WIM sensor and WIM sensor

摘要

The invention relates to a sensor package (6) with long design for a WIM (Weigh in Motion) sensor (1), comprising a first receiving plate (7), a plurality of measuring elements (10), which are arranged equally spaced in a row (15) on the upper side (9) of the first receiving plate (7), an electrode (11) covering all the measuring elements (10), insulation (12) completely covering the electrode (11), and a second receiving plate (8), which covers the insulation (12). In particular, each receiving plate (7, 8) consists of a plurality of receiving elements (13) the end faces (14) of which are juxtaposed in a row (15). According to the invention, the inner end faces (14) of the receiving elements (13) of at least one row (15) have profiles (16) which engage in a form fit manner with the profiles (16) of the adjacent end faces (14) of neighboring receiving elements (13). The invention further relates to a WIM sensor (1) comprising a hollow profile (3) with a tube (4) and two opposing mountings (5) arranged therein, between which a sensor package (6) according to the invention is arranged under initial tension.

主权项

1. Sensor package with long design for being slidably installed into a hollow profile of a WIM (Weigh In Motion) sensor, the hollow profile including a hollow central tube sealed over the entire length of the WIM sensor and having two internal mountings facing each other for exerting an initial tension uniformly on the sensor package, the sensor package comprising:
a first receiving plate configured for being slidably received within the hollow profile of the WIM sensor and for contacting one of the internal mountings, a plurality of measuring elements which are arranged equally spaced in a row on the upper side of the first receiving plate, an electrode that at least indirectly covers all the said measuring elements, an insulation that completely covers the electrode, and a second receiving plate which at least indirectly covers the insulation and is configured for being slidably received within the hollow profile of the WIM sensor and for contacting the other one of the internal mountings,wherein each receiving plate includes a plurality of discrete receiving elements, each opposite end of each receiving element having an end face, the end faces of the receiving elements are juxtaposed in a row,
wherein the inner end faces of the receiving elements have profiles that engage in positive locking manner in the profiles of the adjacent end faces of adjacent receiving elements.
