Testing Background

In the food and pharmaceutical industries, the quality of products is closely related to people's health, so the hygienic conditions of the production process have extremely strict requirements. From the screening of raw materials, to production and processing, packaging and other links, any little hygiene defects may lead to serious consequences. In this context, the choice of production equipment is particularly critical, not only to meet the needs of the production process, but also to meet the strict health standards.

As a kind of advanced size measurement equipment, in-line calipers meet the high precision measurement needs of the food and pharmaceutical industry, and at the same time, with their non-contact measurement characteristics, they perfectly fit the strict hygiene requirements of the industry.

The non-contact measuring principle of in-line calipers

In-line calipers work by emitting a specific wavelength of light that shines on the object to be measured, where the contours of the object will have the effect of blocking or scattering the light. The optical system of the caliper captures these light changes and converts them into electrical or digital signals. After the internal precision algorithm processing, and finally calculate the measured object diameter, thickness and other dimensional parameters.

The common laser caliper utilizes the high directionality and high energy density of laser light. When the laser beam scans over the measured object, the diameter of the object can be accurately calculated based on the blocking time of the object's edge to the laser beam and the scanning speed. This type of measurement eliminates the need for direct contact with the object being measured, avoiding the risk of contamination due to contact, and is particularly suitable for production environments in the food and pharmaceutical industries.

Advantages of non-contact measurement in the food and pharmaceutical industry

1, to protect product health and safety: in food and pharmaceutical production, any tiny impurities may affect product quality. Traditional contact measuring tools, such as calipers, may bring surface dust, bacteria and other contaminants to the product during the measurement process. The non-contact measurement method of the in-line calipers fundamentally eliminates this contamination pathway and ensures that the products are hygienic and safe during the entire production process.

2, improve measurement accuracy and efficiency: food and pharmaceutical industry production is usually continuous, high-speed. Online caliper can measure the products on the production line in real time, and can be measured several times per second, greatly improving the measurement efficiency. At the same time, due to the avoidance of contact measurement may produce wear and tear and measuring force on the measured object, its measurement accuracy is higher, to meet the food and pharmaceutical industries on the product size of the requirements of high precision.

3, to adapt to the complex production environment: food and pharmaceutical production workshop usually exists in high humidity, temperature changes and other complex environmental factors. On-line caliper adopts advanced optical and electronic components, with good resistance to environmental interference, can work stably in such an environment, to ensure the accuracy and reliability of the measurement data.
