CAS DataLoggers says a customer exporting paprika peppers and various fruit in shipping containers recently benefitted from the installation of a dataTaker Intelligent DT80 data logger for environmental monitoring of oxygen levels, CO2, ethylene and temperature, which could not exceed acceptable limits during transport.
“(The DT80) proved to be an effective solution for this application given its portability, the internal battery convenience and its generous memory capacity for up to 10 million recording points,” CAS said.
To ensure none of the critical factors exceeded thresholds, which would jeopardize product quality, CAS selected the DT80 logging solution because of its large memory capacity, sensor connectivity and durability.
Installation included the data logger and a custom dataTaker portable enclosure. The shipping container monitoring system was connected to several sensors, including an oxygen sensor, CO2 sensor, ethylene sensor and temperature sensors.
Encosys, the dataTaker’s Korean distributor, modified a standard dataTaker portable enclosure to ensure that the gas and temperature sensors would be easily connected through the enclosure while the data logger was sealed inside. A connector for an external DC power source was added to the enclosure so the internal battery could be charged when necessary without opening the enclosure. Custom temperature sensors also were provided so the fruit’s internal temperature would be closely monitored during transit.
CAS says the DT80 is a cost-effective data logger for general applications that allows for up to 15 universal analog sensor inputs, and is expandable to 100 channels, and 200 isolated or 300 single-ended analog inputs. And information gathered during transit is easily accessible to personnel via the built-in display.
Additionally, the logger’s rugged design and construction provide reliable operation inside the container, CAS maintained. The stand-alone, low-power DT80 easily connects to a client’s sensors with its analog and digital channels, high-speed counter inputs, phase encoder inputs and programmable serial sensor channels.
Extensive communication capabilities, including a built-in web and FTP server that enables remote access to logged data, configuration and diagnostics, come standard, CAS said. Modbus slave and master functionality enable connection to Modbus sensors and devices, and also to SCADA systems. Smart serial sensor channels allowed interface to RS232, RS485, RS422 and SDI-12 sensors. USB memory stick support also is built-in for data and program transfer.
“With all these features, the client found it convenient to connect with the DT80 locally, remotely or over the internet,” CAS said.
“Past concerns about the logger’s survivability became a non-issue (because) the weather-proofed portable enclosure protected it from accident, as well as external conditions such as water and dust. The case could withstand a full 800 kilograms of stacking loads and even survive being submersed for short periods if necessary.
“Furthermore, if the customer wanted to create a complete turn-key package, connectors for thermocouples or other transducers could be mounted, as well as other equipment such as cell modems, batteries or custom transducers.”
