PSD-500 X-ray Online Thickness Detection System

Interview

Product Detail

Background:

Our company has introduced relevant European product technology and cooperated with domestic scientific research institutes to develop and produce PSD brand series online thickness measurement system. This system is a high-performance equipment for online continuous measurement of the thickness of polyester, polyimide, polypropylene and other films, raw tape, artificial leather, metal calendering products and coating and impregnation products in the production process. It has been widely used in BOPP and BOPET biaxial tensile film production lines. The application of this system is an important means and measure to improve product quality, save raw materials, reduce costs and improve enterprise economic benefits. The system is composed of thickness sensor, computer cabinet, "O" scanning rack and scanning controller.

Working Principle:

For X-ray, after it penetrates the tested material, the attenuation rule of ray intensity I is I=Ioe - μd; Io is the initial ray intensity, I is the ray intensity after passing through the object, μ Is the absorption coefficient, d is the thickness through which the ray passes (gram weight);

When μ and Io are fixed, I is only a function of the measured material d, so the thickness (gram weight) d can be known by measuring I. The principle of the X-ray thickness (gram weight) detector is to convert the thickness or gram weight according to the intensity attenuation when the X-ray penetrates the measured object, that is, measure the X-ray energy absorbed by the measured object, and determine the thickness (gram weight) of the measured product according to the energy value of the X-ray. The received signal is converted into electrical signal by the X-ray receiver, amplified by the preamplifier, and then converted into the actual thickness value or figure for people to watch by the processing system.

Main Functions:

1. Fixed point measurement: the position of fixed point measurement can be set arbitrarily within the scanning range

2. Automatic completion of timing calibration or manual calibration, and the time interval of timing calibration can be set

3. Position compensation calibration

4. Automatic detection, display and processing of system faults

5. Screen display:

*Display the transverse distribution of the measured material thickness according to the working mode of the system scanning measurement or fixed-point measurement

Current value, maximum value, minimum value, average value, mean square deviation and deviation value of curve or longitudinal distribution curve

*The parameter modification screen displays the configuration parameters and can modify the parameters

*Display system working status and fault type

6. Response time of the system: ≤ 0.5 seconds

Product Advantages:

1.The specially designed sensor is non-radioactive and green. The product has been filed by the environmental protection department, and the user does not need to apply for a safety license to use it

2.High precision "C" type scanning frame and motor control

3.High-precision static calibration: the relative error of static calibration of thickness can reach ≤± 0.5%

4.Various compensation functions ensure high accuracy of online dynamic measurement
