Data Loggers, and Data Acquisition Equipment
Traditionally data loggers have been small single purpose devices which record data over time. They are generally battery powered and are meant to be programmed and started with a computer, left in place for some period of time where they operated unattended. The collected and stored data. At some point they were plugged into a computer and the data was downloaded.
A distinction can be made between a data logger and data acquisition equipment in that data acquisition equipment is most often tied to a computer. The computer worked as a controller and a storage device for the data collected by the sensors.
The TV2 temperature data logger combines the features of data loggers and data acquisition equipment providing a flexibility unknown in the past.
This new advanced temperature data logger, in addition to having the functionality of data loggers, and data acquisition equipment, also acts as an alarm and monitor with multiple sensors. It can operate as a stand-alone data logger or as a front-end data collector for a computer or network. It can be used with four sensors as a data logger in the traditional sense storing the logged data in its own memory. But it can also, by plugging it into a LAN automatically copy the collected data to a digital storage device.
The TV2 data logger can be set up directly without having to attach it to a PC. The user sets sensor types, logging intervals, and alarms using the TV2 data logger display. The display can also be used to view a trend chart without the need of a computer front-end. Although the TV2 is powered with wall power its internal backup battery ensures that the TV2 continues to operate even during power outages.
