Museum Collection Care with Real-Time Monitoring

CLEVELAND - Oct. 17, 2019 - PRLog -- Protecting Artwork By Monitoring Conservation Lighting

CAS DataLoggers provided a real-time museum collection care solution for a museum housing fragile paintings and other artwork which needed to be protected against excessive illumination and ultraviolet light. Both these threats could fade or change the color of paint and dyes, so the building needed to make sure their UV light filters and tinted panels were fully effective.


The museum installed 5 T&D RTR-574 Data Loggers on walls adjacent to the highest traffic areas along with a T&D RTR-500 Wireless USB Base Station in a hall nearby. Each data logger included 2 external sensors that simultaneously measured and recorded illuminance/UV intensity and temperature/humidity. The data loggers also calculated the cumulative illuminance and cumulative amount of UV light during recording sessions, which could both be viewed without stopping recording. The large, easy-to-read display allowed users to easily check the logger's recording status, battery status, remaining data capacity and all types of measurements.


While logging, users could select the recording mode as continual or for a specific duration. When using Endless Mode, upon reaching the logging capacity the oldest data was overwritten and recording continued. Each logger's large memory capacity could store up to 8,000 data sets–one data set consisted of readings for all channels in that type of unit: Illuminance, UV intensity, Temperature, and Humidity.

The wireless base station linked wirelessly to the data loggers for downloading data–the wireless communication range, if unobstructed and direct, was about 150 meters (500 ft), and could be extended by registering another RTR-500 as a Repeater and placing it between a Base Station and a Remote or another Repeater. Simple, direct USB connection enabled users to quickly and easily download each datalogger's data directly to a PC via the USB Base Station. Users were also able to download recorded data and current readings from the remote units and send the data by e-mail or FTP–a warning report mail containing alarm details could be sent to up to 4 specified addresses.


The museum's real-time monitoring and alarming needs were all met by the T&D combination data loggers, which confirmed that the UV and illuminance controls remained effective in protecting the collection. Data transmission and accessibility were simplified by USB retrieval, while current readings were always available on the office PC via the online T&D WebStorage Service.
