The Radio Telemetry system was first developed in 1991 in conjunction with the science section of the Victoria and Albert Museum, London and since then has been installed and used by hundreds of museums across Europe. Recently the entire system has been redeveloped to meet the needs not only of museums but also of industry. Including Internet hosting centres, Cyber Centers, Tele Houses or for any environment where a clean controlled atmosphere is essential The system monitors humidity, temperature, lux, ultra violet and volt free contacts
The Transmitters Transmitters are battery powered using 4 “AA” alkaline batteries which provide a theoretical battery life of up to 20 years. Surface mount components have kept the transmitters as small as possible, making them discreet and versatile. Transmitters are available on either 418, 433.92 or 458MHz wide band or narrow band. This means that most users across Europe do not require a radio license. Transmission intervals can be set from 15 seconds upwards, with up to 256 transmitters per site The Receiver The receiver receives data from the transmitters and the repeater (if required) and downloads to the software via a serial port. Receivers can receive on either one or two different radio frequencies and have a battery back up as standard (as with the repeater). If the software is shut down for whatever reason the data is stored in the receiver until its internal memory is full. The receiver is not designed for long term data logging, but has enough memory to last for several days if required |
