X-RAY INSPECTION OF tall, rigid containers made easier
A white paper from Mettler-Toledo explores the challenges metal cans, doypacks, cartons, composite cans/tubes and plastic/glass containers present for x-ray product inspection
all, rigid containers are used extensively across the food industry to package a wide range of products from fruit and vegetables through cereals and beverages to baby food. However, inspecting these types of packaging for physical contaminants and quality defects using x-ray product inspection can prove challenging. Safeline X-ray's white paper Ensuring the safety and integrity of tall, rigid containers explores the challenges metal cans, doypacks, cartons, composite cans/tubes and plastic and glass containers present for x-ray product inspection. The 16-page document then looks at the various food x-ray solutions on the market today for inspection of containers which are capable of overcoming these challenges including blind spots within the container to provide outstanding, reliable and consistent inspection results, irrespective of the application or packaging material. The white paper sub-divides tall, rigid containers into three categories based on the density (low, medium and high) of the packaging used and explores factors affecting the sensitivity of contamination detection in each type of packaging. The paper explains which type of x-ray system: vertical beam, horizontal beam or combination beam is best suited to each type of packaging to help manufacturers select the right food x-ray solution for their own application. In addition to ensuring food and
T
beverages are safe to consume by providing unrivalled contamination detection, the paper reveals that modern x-ray systems are multi-tasking defenders of product and brand quality. This is because in a single pass at high line speeds x-ray machines can simultaneously check fill levels, measure head space, detect missing closures on plastic containers, reject damaged product and detect agglomerates such as flavour and powder lumps. “Traditionally, food processors have needed to implement high power x-ray systems to inspect cans or glass containers at high speeds, sometimes in excess of 1,000 products per minute,” explains Daniela Verhaeg, marketing manager SBU X-ray inspection, Mettler- Toledo Safeline X-ray. “The X37 Series with its new detector technology and class-leading inspection
This technology allows food manufacturers to substantially reduce operational costs while maintaining the utmost level of safety and quality for their products
software is able to offer equal or in some cases improved detection levels while typically only needing one fifth of the standard x-ray energy power consumption. This allows food manufacturers to substantially reduce operational costs while maintaining the utmost level of safety and quality for their products”. Furthermore, the white paper discusses key advancements in x-ray product inspection technology over the past three years including new high gain detectors and enhanced software algorithms along with their benefits to help food and beverage manufacturers evaluate special features and/or compare the capability of different machine brands.

VERY SMALL PRESSURE PULSES NO PROBLEM FOR MINI SENSOR
The new Type 601C miniature pressure sensor from Kistler Instruments available in both charge output and voltage (IEPE) output types is suitable for a wide variety of dynamic pressure measurement applications. The high sensitivity of the PiezoStar crystal developed by Kistler, much higher than
that possible with quartz, allows small pressure fluctuations which are superimposed on static pressures to be measured with exceptional resolution. In addition to the high sensitivity and small size the charge output version has a wide operating temperature range from -196 to + 350°C at pressures up to 250 bar. The 601C benefits for a high natural frequency (>215kHz), making it a viable solution for applications with dynamic pressure events. The diaphragm design is optimised for applications where the pressure
measurement is simultaneously accompanied by high temperature transients such as in testing of closed vessels, airbags, pyrotechnics etc. The new sensors are available in standard (37.65mm overall) and short (14.85mm overall) welded, hermetically sealed housings. Typical applications include pressure pulsation on pumps and
compressors and dynamic measurements on pyrotechnic devices. Kistler Instruments
