Museum Environmental Monitoring Protects Exhibits

CLEVELAND - OhioPen -- Wireless Monitoring Satisfies Museum Environmental Standards

Eltek has supplied the next-generation museum environmental monitoring solution for the interior of a prestigious museum located in Cambridge, England to ensure that the exhibits are in a controlled and non-destructive environment. The site is approximately one square kilometer but in actual surface area is much larger, as it consists of 4 levels and some basement area.

This was complicated by the fact that the building is a stone structure with modern construction extensions. Therefore museum curators needed a flexible monitoring system with a broad range of data logging capabilities. Staff also requested analysis software to track readings by room to get a highly accurate environmental profile to aid in long-term preservation.

Installation

Due to the sheer size of the museum, it would be extremely difficult to install a conventional wired monitoring system. Individual data loggers could have been used in different areas, but this would make it difficult to collect and aggregate the data with a cost-effective solution. With this in mind, Eltek supplied the museum with a wireless data logging system to meet all of its environmental monitoring requirements.

Eltek Gen II Wireless Radio Data Loggers have been designed to log the environmental data and generate alarms for parameters out of the desired range. This system supports up to 128 transmitter units and up to 250 measurement channels.

Usage

The museum's 54 model GD-10 transmitters and 7 model GL-70 environmental data loggers make a total of 159 individual sensor channels. The loggers transmit data to the centrally located RX250AL receiver which is a large setup by any manufacturer's standards! This combination ensures optimal coverage for all exhibits. The GD-10 transmitters use built-in temperature and humidity sensors while the GL-70 units have an internal temperature, humidity, visible light, and ultraviolet light (UV) sensors to record the desired environmental parameters.

Each Wireless Transmitter digitizes the environmental data in its location and transmits it to the central RX250AL Data Logging Receiver. Data is stored in the receiver which then sends the data to an office PC via USB, Ethernet, serial or cellular modem communication. For truly independent and robust monitoring, the system will continue functioning in the event of PC or mains AC failure, and it's not necessary to have a PC permanently connected because of the internal memory in the RX250AL. The museum's system also uses a pair of Eltek RP250GD repeaters to extend the transmitter wireless range and cover this difficult site in terms of radio communications.
