[Pressure transducer for radiotelemetric studies].
Designed has been a combined transformer for pressure on the principle of the photoelectric effect. It records directly the pressure produced within the system and outside through the arrow mechanism of the manometer for blood pressure, and transforms the mechanical fluctuations of the membrane into electric ones. Used has been a blood presser manometer additionally supplied with a photoelement, a tiny electric bulb, and a metal lamelle. The photoelement is connected into the electric scheme of a PC-generator of a 1600-2000 Hz frequency, and the latter produces frequency that supplies the carrying frequency of the radiotransmitter. Shown are original records made at various points of the dorsal sac of the rumen of a ewe as well as of the carotic artery of a cow.
