Environmental Monitoring in a Manufacturing Plant

Accsense VersaLog Records Both Temperature and Humidity

CHESTERLAND OH — CAS DataLoggers recently delivered the datalogging solution for a production plant whose process machinery was mysteriously slowing down and causing production delays. As part of searching for the cause, the plant engineer wanted to gather environmental data on his critical electrical equipment. This application required a portable data logger with the versatility to measure temperature and humidity which was capable of standalone operation without a PC, and which included software with graphing capabilities for data analysis.

The company installed an Accsense VersaLog Humidity and Temperature Data Logger adjacent to their machinery under test. An onsite technician setup the data logger to measure machine conditions by taking both a temperature and humidity reading once every 10 minutes. If desired, the user can set the sampling rate anywhere between every 20 milliseconds to every 12 hours. Using its external Sensirion RH digital sensor, the VersaLog monitors temperature on one channel and relative humidity on the other, storing up to 4MB of readings on its non-volatile flash memory.

The logger's 5-year lithium battery enables standalone operation, while its aluminum enclosure and conformal coating helps protect it from industrial accidents. The datalogger utilizes multiple communications options including USB, Serial port and Ethernet Connections; in this case the user just collects the data by pulling the flash drive. With the included SiteView software's intuitive graphic interface, the technician quickly setup and configured the datalogger. This way he can view all the data in real time and organize it in charts and graphs.

Using SiteView, the technician can also view all alarm triggers, zoom in on specific data, annotate and label graph functions, and view dynamic statistics. With SiteView, users can set high and low alarm limits for the alarm outputs and if necessary trigger external devices such as an alarm light. For fast downloading, SiteView supports communication speeds up to 115200 bps as well as multiple file loading to quickly access all data. Once downloaded, the data can be plotted and analyzed on an office PC.

As a result of installing a data logger to automatically perform his environmental monitoring, the plant's engineer will be able to identify if his machinery is being adversely affected by excessive temperature and humidity or if the cause lies elsewhere. Accsense Versalog's portability enables standalone, simple operation at a cost well within the operating budget. The datalogger also eliminates the need for workers to take time-consuming manual measurements that would be much less accurate than sensor-gathered data. This frees up technicians for more demanding work. In the near future, if it's found that the plant's temperature and humidity are to blame, this alone will pay for the datalogger by preventing another process delay or halt.
