The controlling PC has to be kept away from the incinerators and is located in an office 50 metres distant. The sensors, controllers and instruments are 20 to 30 meters apart. The Microlink 1500 is designed for distributed measurements such as these, and uses RS485 twisted pair communications. The data logging software, called Windmill Logger, is extremely flexible. It can automatically create new files at given intervals, every day or every week for example.
Several loggers can run simultaneously.
This allows logging from different rigs to be started and stopped independently, or for several sets of channels to be logged at different rates. Each set of data is time and date stamped. The Microlink system has proved so effective that Biodata is currently expanding it to monitor more rotary kiln incinerators.
