A very compact and simple sensor probe, its cost becomes lower and the device operation becomes easier. This kind of sensor probe has been used to detect the thickness of the pipe wall in the plastic pipe production line. In addition, this device is also very suitable for measuring coatings on fiber composites.

Terahertz's new sensor unique features and value
The terahertz sensor is a safe non-radioactive in-line measurement solution for a variety of applications such as multilayer plastic sheet extrusion, multilayer foam extrusion, rubber tire calendering, multi-layer conveyor belts, roofing materials, single Roofing (such as TPO or EPDM) and many other uses. Terahertz sensors offer a variety of unique new measurement capabilities that cannot be achieved in any other single sensor solution. The sensor can measure thickness, grammage and density simultaneously, while other solutions require a physical thickness sensor and another physical grammage sensor to measure density. Terahertz sensors also enable multilayer measurements of materials, providing intuitive thickness measurements and insensitivity to color or additives without any specific calibration of the product.
The terahertz sensor can be used as a single-sided reflective sensor to highly accurately measure the thickness of a multilayer sheet structure and can be used to measure all types of materials other than metals and other conductive materials.

Another application of this new terahertz sensor probe is to verify paints and coatings on fiber reinforced composites. People can use eddy current testing technology to detect some metal-based materials, such as the detection of metal flakes in the automotive industry; but eddy current testing technology is not suitable for poorly conductive fiber composite materials. Therefore, with the wide application of composite materials in the automotive, aerospace, aerospace and energy fields, people urgently need a reliable detection method. And this new type of terahertz sensor probe can solve this problem. Terahertz technology will achieve more success in the coming years and soon become a mainstream non-destructive testing tool.

Terahertz sensor advantages:
New terahertz technology combined with the most advanced design;
Only one sensor can be used to simultaneously measure total thickness, grammage, density, and layer detection technology;
Single-layer or surface PP layer, EVOH barrier layer, bottom PP layer and other multi-layer product structure accurate online measurement;
Safe and non-radioactive, without environmental regulatory approval (unlike isotope radioactive sources or X-rays);
To better control and improve product quality, save raw materials, increase production, and reduce scrap.
