QCS S4000

It consists of a circular container, part cast alloy and part chrome-plated brass.
Inside, the source is arranged in a special block made in such a way as to prevent it from escaping, even in the event of impact or mechanical accident or violent fire (melting limit temperature and no danger of contamination 1,300° C).
A source block shutter consisting of soft and hard layers of alloy material is provided, which ensures 95% interception of radioactive emissions in the closed state.
A second shutter consisting of a stable sample is inserted for self-calibration of sensitivity.
The control mechanism of the shutter is achieved by an electromagnet system, which guarantees perfect closing operation even in the event of a power failure. Two limit switches at the end of the source closing flag signal the open-closed status of the shutter.
The system still allows external intervention on the opening and closing mechanism of the source. The entire emitter assembly is thermostabilised and is normally adjusted to approximately +10°C of the temperature of the paper being measured. The collimator hole of the beam emitter is protected by a membrane, made of thin material, but of very high mechanical resistance.
A thermoregulated air jet ensures the cleaning of the protective membrane.
The connections are made with screw couplings, gold-plated contacts of MIL grade.
The housing is enclosed in a protective hood

It utilises the property of water to absorb electromagnetic waves at certain frequencies. The dielectric generated by the moisture contained in the paper is measured at a fixed frequency. This value is then converted into an analogue signal with 24-bit resolution.

It measures the magnetic field generated by a permanent magnet to provide the Z-indication of the position of the top and bottom plane.

Sensor Self-calibration

The sensors are equipped with an intelligent auto-calibration system that takes into account machine stops, start-ups, breakages and deviations from zero values to program calibration times.
The basis weight sensor is equipped with a sensitivity autocalibration system that uses a stable sample.

Supervision Software

Beltro10 is an automation software for paper machines and provides :

1. real-time information on current production (instant views, cross profiles, etc.);
2. network storage of historical production data (averages, statistics and trends);
3. signalling and storage of alarms for faults or abnormal measurement values;
4. possibility of storing production codes (set points, corrections, adjustment parameters, etc.) for each type of card;
5. Two controllers (advanced proportional) specifically designed and tested for adjustments on paper production machine times;
6. full-colour printouts of all data supplied, either automatically or on request;

Through a friendly interface it is possible to access intuitively and quickly all programme pages for monitoring and intervention on the system.
The use of the Beltro10 software allows production to be considerably improved thanks to the real-time processing of the situation, the consequent rapid correction via the controllers and the availability of historical data for statistical and behavioural analyses.
