FIBRE OPTIC TEMPERATURE MEASUREMENTS FOR HOSTILE ENVIRONMENTS

The new Vanzetti system for monitoring temperatures, can be applied in harsh conditions which often pose almost insurmountable problems for conventional techniques using sensors, such as thermocouples, requiring contact with the part under observation. The new technique uses the principles of fibre optics to detect the infra-red radiation emitted by the source being monitored. A single fibre or bundle of fibres gathers the IR radiation from the target and transmits it to the IR detector where it is converted into a suitable voltage signal. The fibres, even when bent, can transmit the radiation over distances up to 30 ft without distortion; they are sensitive only to the infra-red portion of the spectrum and are not activated by flames or fumes. Temperatuers of 60 degrees to over 1,000 degrees C can be measured to an accuracy of better than 1 degrees. For extreme temperatures, or otherwise severe conditions, the fibre probe is protected by air or inert-gas purging or by water cooling. Vanzetti monitoring systems are available in the UK from Euro Electronic Instruments. Order from: BSRA as No. 47,541.
