Description

(54) СПОСОБ АКУСТИЧЕСКОГО КОНТРОЛЯ ПОПЕРЕЧНОГО СЕЧЕНИЯ ИЗДЕЛИЙ ТЕКСТИЛЬНОЙ ПРОМЫШЛЕННОСТИ(54) METHOD OF ACOUSTIC CONTROL OF TRANSVERSE SECTION OF PRODUCTS OF TEXTILE INDUSTRY

Depending on the cross-sectional area of the product, the well value of the phase shift varies, and, consequently, the value of the controlled vepichina.

Дл  устранени  действи  внешних факторов, которые могут сказьшатьс  на величине времени про хождени  сиггала или на частоте резонанса и тем самым могут исказить контролируемую величину, возможно использование эталонных устройств (на чертеже не показано), которые подвергаютс  тем же самым внешним воздействи м, что и измерительное акустическое поле.To eliminate the effects of external factors that may affect the time spent walking a siggal or the resonance frequency and thus may distort the monitored value, it is possible to use reference devices (not shown) that are subject to the same external effects as the measuring device. acoustic field.
