Buckland, I.G., Butlin, R.N. and Annable, D.J., 1976. GAS EXPLOSIONS IN BUIIDINGS PART VI REMOTELY CONTROLLED GAS SAMPLING PROBE AND CLOSURE VALVES FOR A GAS EXPLOSION CHAMBER. Fire Research Notes 1052
The Engineering Services Section have designed in collaboration with ITH Section, a new Sampling Probe System for the 28 m^3 explosion chamber at Cardington. The system is remotely operated with digital indication of the probe position. The gas mixture in the cell can be sampled at any point between the ceiling and the bottom of the extended probe. After filling the chamber the probe is retracted, thus avoiding the possibility of the probe affecting the characteristics of an ensuing explosion. All the gas inlet and exhaust valves on the rig are remotely operated using the same power source for reasons of safety and convenience.
