The Cargolog® is suited to monitor the transportation of power transformers or other heavy loads. Integrated sensors measure accelerations in three axis, tilt, humidity and temperature. There is also a special unit that can record vibrations over a long term. All parameters can be pre-set on a laptop/PC with the software. A communication module is connected via USB to transmit the parameters on the registration unit. It is just placed on top of the unit and communicates via infrared interface.
Outside LEDs on the unit show if these pre-set limit values have been exceeded. A large lithium battery enables the device to record even during long-term shipments that may last up to one year. The device is mounted with an installation unit that is fixed by four screws. It is also possible to install the device with magnets or straps. An aluminum protection housing is available.
The internal memory allows to record up to 38,800 events. All events are stored with a time stamp. Accelerations are recorded in a standard range up to 10G with a resolution of 0,01G. Special units are available with a range up to 2,5G, 25G or 100G. Together with the G amplitude, also the duration is stored to determine the frequency. The temperature range is from -40°C to +80°C (-40°F to +176°F). An optional GPS function permits to see after the transport, where an event occured. Therefore you need a version with antenna and integrated receiver.
After the transport, data is downloaded with the communication module. With an extensive visualization software, you can easily see the maximum values and scale the view to your needs. All data can be printed or saved and converted to Excel.
The first Cargolog® units were installed 10 years ago, so the device is really field-tested. Apart from power transformer transportation supervison, it is also used to monitor shipments of generators, turbines, paper rolls and other heavy cargo.
