Non contact remote microwave sensor, can be used in any point of the paper machine where an high accuracy and direct measure of the moisture content in the paper sheet is needed, eg. exit press section, dry section etc..
Quality – Efficiency - Runnability
The paper sheet’s water content, when it exits the press section, is critical in the pulp and paper production process because of the direct impact this has on the operation of the dryer section with potentially significant effects on energy consumption and the machine’s runnability.
In this section, a no-contact measurement is ideal for directly measuring the sheet of paper.
Unique patented technology
The sensor is based on an advanced measurement concept that uses an innovative microwave reflection technique that delivers high performance in terms of:
Resolution
Wide range of measurement from 0 to 800g/m2
Accuracy
R1 allows to evaluate the consistency of the paper online during production and therefore provides direct feedback in real time for the optimization of the process and product quality.
Immunity
Immunity from any environmental interference such as vibration, temperature, humidity and dust.
Microwave technology is used to make no-contact measurements of physical and physical-chemical parameters including moisture in the pulp or paper sheet as well as other sheet-like materials found in several other industrial processes.
The R1 sensor measures the water content with accuracy, keeping a safe distance from the sheet without creating interference in the sheet’s path
Mains features
- No-contact measurement
- Wide range of measurement from 0 to 800g/m2
- Resolution of 0.1 g/m2
- High repeatability and reliability
- High immunity from colour and temperature
- Easy installation (single cable connection)
- Simple machine interfacing with analogue output
- Advanced data processing features with FFT analysis
Flexible positioning
R1 No-contact remote microwave sensor, can measure moisture directly on the running sheet of paper.
The R1 can be easily placed at the end of the press section or inside the dryer section with a proper cooling system.
The R1 has two parts: the sensor and the reflector. They are positioned one on each side of the sheet.
The reflector is a completely passive device with no electrical connection needed and a thickness of less than 2cm.
Data analysis
The R1 sensor can make very fast measurements. The data, in digital form, is acquired by a computer and then processed and stored.
Thanks to the system’s accuracy and high rate of measurement, advanced analysis (FFT) can be performed on the raw moisture data.
This information can help isolate mechanical issues in the process such as unwanted vibration.
The data collected from each sensor is saved in memory for easy review.
Easy connection to the existing mill control system through flexible, standard, analogue DCS/QCS output (VOLTAGE or CURRENT).
