Description:
The QMS 70U-170 is a compact and robust sensor using an unique capacitive sensor technique as well as highly sophisticated electronics. QMS 70U-170 is designed for materials, products, product parts - hereafter denoted as objects - really difficult to be detected. These objects may intermittently aligned and either fixed on carriers or enclosed in paper or foils. The objects themselves may be made of any non-metallic materials, adhesive tapes, cellulose, textile, cardboard etc.
The single objects may pass the sensing area either sporadically or intermittently aligned. Due to the high sensor gap and depth the thickness of the objects may vary from 1 mm to 10 mm and reach 120 mm inside the sensor gap.
As the carrier or enclosure material is continuous and constant the sensor zeroes the carrier and enclosure materialand concentrates only on the objects to be detected.
The QMS 70U-170 is offered as a complete detection sensor unit with a switching output. Otherwise the QMS 70U-170 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.
