DeltaTRAK (Pleasanton, Calif., USA) has announced a new application of its automated, wireless, real-time monitoring, recording and alarm system to monitor out time of temperature-sensitive composite prepregs. The FlashLink RF (radio frequency) Wireless System collects information around the clock, with real-time data visible on a PC monitor at any time; data are also stored electronically. Alarms can be set up to send alerts to personnel, indicating occurrences of temperature excursions or amount of out-time (shelf life) remaining for inventory management purposes.
The FlashLink RF System automatically monitors prepreg rolls from fabrication to shipment, and can further track them in transit to the customer. RF data loggers send signals to a wireless receiver, which is a gateway between the wireless network and corporate IT systems. Wireless repeaters and Bluetooth Range Extenders boost signals from Loggers to Receiver, in order to overcome physical obstacles in line of site. The software logs, tracks and reports data.
As a prepreg roll comes off the fabrication line, a barcode label is printed, attached to the roll and correlated to a DeltaTRAK FlashLink RF Logger, which is also placed on the roll. Each roll would have a wireless logger attached to it before being placed into the freezer, and, at this point, the system begins clocking shelf life. As each roll leaves the freezer, the logger sends the time information to the network; upon returning to the freezer, time back in is transmitted. The software then calculates out-time, as well as the percent of life remaining for each roll, based on time spent out of cold storage. Data is reported in graph, text, or Excel format. The software can also be programmed to emit an audible alarm on the computer, and/or send an email alert or text message when product is close to out-time limits. It also allows personnel
to access data remotely.
