Description

В отличие от известных электроакустических измерителей температуры , основанных на иснользовании генераторов электромагнитных колебаний с акустической обратной св зью, позвол ющей выделить резонансную частоту в полом резонаторе, заполкешюм газом, предлагаемое устройство нри его конструктивной простоте обеспечивает измерение в достаточно широком интервале температу). С целью расширени  диапазона измер емых температур и повыше1 и  точности измерений, резонатор занолн етс  газом с высоким тер.игературным коэффициентом скорости раснространени  звука в этой среде.In contrast to the known electroacoustic temperature meters, based on the use of electromagnetic oscillators with acoustic feedback, allowing to select the resonant frequency in the hollow resonator, filled with gas, the proposed device, with its constructive simplicity, provides measurement in a fairly wide range of temperatures). In order to expand the range of measured temperatures and higher1 and accuracy of measurements, the resonator is filled with gas with a high thermal coefficient of sound propagation velocity in this medium.

The resonator tube is filled with different gases depending on the interval of measured temperatures and As a generator of electromagnetic oscillations, an ordinary wide-band amplifier is used - a microphone 3 is connected to the input, and a telephone 2 is connected to the output. The acoustic feedback resulting from such a connection leads to excitation of the amplifier at the resonant frequency of oscillations of the gas column in the resonator /, immersed during ipa6oTbi on a medium, the temperature of which is to be determined. The frequency of the oscillation H is measured by a pulse counter o.
