SH-8C near-infrared online thickness system, with 4~20mA output.
SH-8C online thickness system adopts non-contact measurement mode, output 4~20mA current signal or 0~5V voltage signal, can communicate with computer through RS485, conforms to MODBUS bus protocol, optional printer module, print data on site, also Cloud technology can be selected to view the measurement data of the instrument from anywhere in the world via mobile phone or computer.
The measurement accuracy is almost independent of the color, density, and particle of the object. The SH-8C online moisture detector adopts the new technology of moisture measurement. The probe is waterproof and dustproof. The excellent solid casing can resist accidental impact. The whole machine can work in harsh environment for a long time. It is easy to debug and can be installed in various ways. Easy, high precision and wide application range.
The SH-8C online thickness system uses near-infrared light illumination technology to continuously and non-contactly detect the thickness of the coating. It is easy to operate, very stable and accurate, and has no problem for the human body.
1. The online thickness system is very important in the production process of adhesive products. It can test the thickness of water glue, oil glue and hot melt glue online.
2. The thickness detector is directly mounted on the top of the coating head through the scanning frame, which can accurately detect whether the thickness of the coating exceeds the standard and uniformity, reduce the waste of failing products, improve product quality, reduce the consumption of raw materials, and can greatly improve Production efficiency, increase production. Moreover, the sampling and testing of the semi-finished products is avoided, and the breakage is reduced.
3. Near-infrared spectroscopy (NIR) analysis technology is a high-tech analytical technology that is rapidly developing in the field of analytical chemistry. Near-infrared spectroscopy belongs to the frequency doubling and dominant-frequency absorption spectroscopy of molecular vibrational spectroscopy, mainly due to the non-resonance of molecular vibrations. When the ground state transitions to a high-energy level, it has a strong penetrating power, and its appearance can be said to bring another revolution in analytical technology.
4. The SH-8C film thickness on-line measuring instrument uses a pair of infrared probes to form an infrared emitting and receiving system. When the measured object passes through the set of probes, the infrared rays emitted from the emitting end are passed by the detected object. The characteristic of the measured object is attenuated to determine the thickness of the measured object, and then the computer is used as the main processor to perform functions such as online signal acquisition and processing, digital image display, and alarm. The SH-8C Online Thickness Gauge is an accurate, environmentally friendly diffuse reflectance on-line thickness gauge that measures film thickness quickly and continuously in a simple, non-contact manner. The measuring instrument is designed to be applied to the film production line, and the die bolt is automatically controlled by the feedback signal to make the film thickness uniform, improve the product quality, and reduce the loss of raw materials. Product application range: fabric, coating, biaxial stretching production line; BOPP, BOPET, BOPS, BOPA, etc.; CPP cast film production line; extruded sheet production line; PVC calendering production line; coating production line; fiber, steel cord four roll calendering Production line; non-woven production line; float glass production line; glass fiber production line, paper production line, etc.
First, there are usually three types of coatings:
1. Water-based coating: the concentration of the solution is between 10% and 60%
2. Oily coating: solvent is organic solution, similar to waterborne coating
3. Extrusion and hot melt coating: coated on the substrate is a melt solution.
