Description:

The QMS 70U – 230 is a compact and robust sensor using a unique capacitive sensor technique as well as highly sophisticated electronics. The QMS 70U – 230 covers solutions of a wide range of applications, where voluminous or thin, non-metalized objects, products and materials are to be inspected or controlled. The QMS 70U – 230 is easily mounted in machines mainly without changes in machine parts needed. It measures a continuous material flow as well as products intermittently aligned on carriers like foils or papers. The product may also be packaged or enclosed. The QMS 70U – 230 can be delivered with a switching output, signalising too much or too little material flow passing the sensor electrode within the sensor gap.

Mainly the QMS 70U – 230 is used as analog version, giving a dynamical 0…10V analog signal, proportional to the basis weight actually passing the sensor electrode. This output is used by an HST control system like the HST Flow Controller, HST Analyser or Ranger to derive and evaluate important qualitative and quantitative information and data. Qualitative information and data may concern production, product, machine and material deficiencies. Weight, weight distribution, statistics etc. are classified to the quantitative information and data.

In the most common application the QMS 70U – 230 is installed into a sanitary napkin machine at a place, where the product is compressed and shaped, short before folding. Here the weight distribution and single weight can be measured with high precision, during high machine speed (up to 3000 products per minute)

Like all QMS 70 sensors, the QMS 70U – 230 is easy to install and brought into operation. Adjustment is performed, if needed at all at the first commissioning. Due to the auto-taring feature, no re-adjustment is needed normally. Pollution has no effect on sensor operation in a very wide extent and abrasion is kept very low due to the robust sensor electrode.
