摘要： A radiation receiver including three receiver layers for infrared gas analysis. The first and third layers are connected in parallel, and their pressure is compared with that of the second or middle layer to derive a pressure difference which compensates for certain measurement problems found in prior art devices.

摘要： An auxiliary signal for the compensation of the difference signal created in optical-pneumatic receivers due to the absorption of radiation, such compensation being achieved by one or more electrical-pneumatic transmitters connected directly to the receiver chambers.
