movement, the 1,000-5,000fps range is suitable for many types of product durability testing, automotive component testing and some microscopy applications.” Fastec Imaging’s IL5 High-Speed

resolution and more than 29,000fps at smaller resolutions. The camera is able to save images to an SSD or SD card while recording high-speed bursts of hundreds or even thousands of images at a time, which means that the IL5 is always ready for the next high-speed snapshot that needs to be taken. The base model starts below $9,000 and so is a cost-effective solution to recording high-speed events for slow motion analysis. The Fastec IL5 camera is built for flexibility and

S applications to be made in

ince their introduction in 2015, Fastec IL5 cameras (alongside the TS5 model) have been used in a wide variety of scientific

and industrial applications. Tim Brandt, product manager for Fastec,

comments, “The performance update broadens the sweet spot of the camera to include frame rates over 5,000fps, which can now be achieved at much higher resolutions than before. While 250-1,000fps is sufficient for capturing most industrial machine

order to see what errors have been missed. The slow motion replay can be used to analyse

and troubleshoot common issues with web handling machinery equipment such as machine vibration, tension control, warp, thickness variation, or slitting misalignment. There is an IL5 to fit a variety of application

needs; the four models boast crisp, clean video from 2,560x2,080 at 230fps to 800x600 at 1,650fps. All models record over 3,200fps at VGA

ease of use, it can be controlled over Gigabit Ethernet via Fastec FasMotion software on PC or Mac systems, or via the built-in web interface with any chosen web browser on a PC, Mac, tablet or even a smartphone. Using the Long-Record (LR) FasCorder Mode,

the camera can be operated as a regular camcorder to record and pause as needed. Follow action, stop recording, review what has been taken and then append additional footage at will, even after a power cycle. Unlike traditional high-speed camera systems

that only record for a few seconds and require careful triggering, the LR option can record at high speed for minutes at high resolutions to hours at reduced resolutions. On-board SSDs for use of this application are available from 256GB to 2TB.

Unwind tension controllerutilising load cell feedback

the Z4-UL. The Z4-UL is designed for unwind tension zones utilising load cell feedback for tension measurement with a full range of functions and features to maximise production capabilities. The Z4-UL features an all new seven day trend


storage capability for recording production run data and the first ever seven-inch high definition web tension control interface. It is available in three different configurations: circuit board only (Z4-UL-B), enclosure (Z4-UL-E), or remote installation (Z4-UL-R). Applications specialist, Doug Brockelbank,

says, “The Z4-UL represents the next iteration of our tension controller technology, introducing a variety of new features, functions and benefits for manufacturers to achieve more with their machines. The Z4-UL continues our advancement of the technological capabilities of our tension controllers and lays the foundation for new innovations we will soon be bringing to the industry.”

ontalvo, international specialist in web tension control, has announced the launch of its latest web tension controller

Soft-Start:Minimises tension upsets during start up. Anti-Coast: Prevents web tension from dropping during rapid deceleration. Splice: The Z4-UL maintains tension on materials during flying splice, resulting in successful splices without tension changes. Web Break Detection: There are programmable alarms and a stop machine should a break occur, reducing waste and productivity loss. Progressive Gain: Ensures uniform stability from full roll all the way down to the core. Variable Wrap Angle Technology: Allows for load cells to be mounted on rolls directly after the unwind roll or directly before the rewind roll, without having to isolate that tension sensing roll. Also allows for single sided roller contact to a material. Range Expansion: Allows multiple types of materials and tensions on one machine to run, gain greater control at lower torque ranges, run high mass rolls at lighter tensions, and run low torque and tension applications that require high torque to stop. Dual Calibration: Calibrate the same load cell(s) with two different ranges. This is ideal for driven applications where the tension ranges are very high. Remote Setpoint: Remotely input or adjust tension setpoint. The Z4-UL remote version (Z4-UL-R) allows installation of the circuit board and the HMI in separate locations. User Defined Units and Scales: Customise the interface, units, and scale to meet requirements. Integrated Tension Indication: Clear, easy to read, integrated digital version of an analog metre keeps you informed of the exact tension you are running.
