PRODUCTS EDITOR'S CHOICE FAST BISCUIT INSPECTION COMPACT LASER At Nutrition &


Santé’s organic and health food manufacturing facility,


biscuits roll off the production lines in stacks of four or five units and are then


wrapped and inserted into cardboard packaging at high speed. It is essential, however, that broken biscuits are detected, so the company turned to Keyence for a solution that would allow a window of


just 150ms for inspecting each stack. With Keyence’s CV-5000 vision system, edge


detection/position is performed by two cameras placed about 20cm above the biscuits on each line. A different program has to be set for each of the thirty-odd shapes and sizes conveyed on each line. Alongside edge detection/position, there 19 other inspection


tools available with Keyence’s CV-5000 vision systems. Each of the inspection tools makes it possible to set up a detection application simply and quickly. The system allows one million pixels to be processed in


20.5ms, which means it is possible to perform multiple inspections reliably, the company explains. The CV-5000 Series are controlled by a high-speed colour


image processing engine and RISC (Reduced Instruction Set Computer) CPU. Both are supplemented by two DSPs (Digital Signal Processors) designed specifically for image processing. All models use these four processors to achieve parallel processing and attain fast processing speed. The system is also equipped with a double-buffer memory that allows it to accept the next trigger input while an image is being processed. Commenting on the benefits, Fabien Ployon, production


manger, said: “Because the CV-5000 vision system works faster than our lines, it gives us definite leeway. It runs seven days a week and we’re very satisfied with its detection reliability and stability.”

New from FLIR is the A310 ex, an ATEX compliant solution where the thermal imaging camera (a FLIR A310) is mounted in an enclosure. This means assets can be monitored in explosive atmospheres, with applications including process monitoring, quality control and fire detection. The solution can be installed in classification


zones one, two, 21 and 22, with the certification comprising the whole system including the enclosure and components inside – such as the thermal imaging camera, heater and integrated controller. The flame-proof enclosure ‘d’ prevents any explosion transmission from the inside of the enclosure to the outside. This is also IP67 rated and comes with a heater which effectively prevents fogging and freezing of the protection window. The integrated


controller features several digital I/O channels and

sensors for temperature, humidity and pressure, and is equipped with two fibre optic and two Ethernet ports, enabling a flexible network integration in star or ring topologies. The FLIR A310 camera comes


with measurement functions like spot, area and difference temperature measurement. It also has built-in alarm functions and automatically sends analysis results, IR images and more as an e-mail on schedule or at alarm. Additional features include thermal sensitivity of < 50mK.

New to DJB Instruments UK’s range of accelerometers and instrumentation is the VB/01, a low cost battery powered single channel IEPE accelerometer supply which provides 4mA constant current supply at 18VDC. This features LED indicators for power, short circuit and open circuit and is, the company explains, ideal for field testing where no mains power is available. Also new is the 8401 IEPE sensor


simulator. This installs in place of an IEPE accelerometer (or other sensor) and accepts signals from a voltage function generator, allowing the user to verify signal conditioning settings and cable integrity. The 8401 uses the power from the IEPE signal conditioning to complete the checks.

PROFILE SENSORS With Micro-Epsilon’s new lightweight scanCONTROL 2600/ 2900 COMPACT 2D/3D laser profile sensors, the controller and electronics are integrated directly in the sensor, making the devices suitable for high precision profile and dimensional measurements in a variety of applications. These are available with measuring ranges of 25mm, 50mm and 100mm; with linearity 0.16% of the measuring rate. The scanCONTROL 2600 has up to


640 points across the line width and a profile frequency of up to 4,000Hz. The 2,900 version has 1,280 points across the line width and is suitable for


HIGH ACCURACY USB DAQ MODULE


New from Data Translation is the high accuracy DT9844 USB data acquisition module. This has 32 analogue inputs, a 1MHz A/D converter and 20-bit A/D resolution. Even at the maximum overall sampling rate of 640 kHz, this achieves high system accuracy and minimizes noise and crosstalk. In addition to the 32SE or 16DI analogue inputs, the new module also features 32 digital I/O channels and five counter/timers. All analogue channels can be run


automation tasks that require both high resolutions and high profile frequencies. The 2900 series offers a profile frequency of up to 2,000Hz. The sensors are equipped with


a Gigabit Ethernet interface for transferring profile data, as well as a multi-purpose connector for RS422, Digital In (HTL/TTL), power supply and synchronisation. They also support Power-over-Ethernet (PoE). All scanCONTROL series sensors are


designed with a high speed external profile trigger input.

simultaneously with the digital I/O channels; and the digital outputs can also be used for synchronising external devices. The module also provides flexible trigger functions with pre- and post-triggers and an external clock input. Also included is the QuickDAQ measurement software which provides data acquisition, display and logging functionality and allows data export.
