The QMS 70 is a compact and robust sensor using an unique capacitive sensor technique as well as highlys ophisticated electronics. The QMS 70 is designed for materials, products, product parts - hereafter denoted as objects - really difficult to be detected or to be determined by weight. These objects may be intermittently aligned and either fixed on carriers or enclosed in paper or foils. The objects themselves may be made of any thinnon-metallic materials, adhesive tapes, glue, cellulose, textiles etc.
The single sided sensor with its sensing area at the top enables detection and weight quantity control of thin objects.
The objects or materials are in contact with the sensor top and are guided by two steel plates. Detection or weight quantity measurement may be performed through carriers like paper, foil or fleece webs. For that the objects andmaterials to be measured may be enclosed or be on the opposite side of the web.
The QMS 70 is offered as a complete detection sensor unit with a switching output. Otherwise the QMS 70 version with analog output enables the interconnection to control and inspection systems like the HST Ranger and HST Analyser.
Bringing into operation is very easy. Adjustment is performed, if needed at all, at the first commissioning. Due to the auto-taring function, no re-adjustment is needed normally. Pollution and abrasion have no effect on sensor operation in a very wide extent.
