SYC-1A仪器是一台多种探测频率,多用途的声波探测仪。它可用压电换能器或锤击激发发射声波,在现场进行几千至几十千周的声波或超声波短距离(零点几米至二、三十米)岩体探测,通过换接部分印刷电路板,还可以对岩石试件进行0.1至1.5兆周的超声波测试,从而对岩体稳定性进行综合评价。归纳起来,该仪器可完成以下测试任务:1.对地下洞室周边所布置的声波测孔(孔径约φ44mm左右,孔深4～6米)进行
SYC-1A instrument is a variety of detection frequency, multi-purpose sonic detector. It can use piezoelectric transducers or hammer excitation emission acoustic waves in the field for thousands to tens of thousands of weeks of sonic or ultrasonic short range (zero a few meters to two, thirty meters) rock detection, through the exchange part of the printed circuit Board, you can also test the rock specimens 0.1 to 1.5 trillion weeks of ultrasonic testing, rock stability to conduct a comprehensive evaluation. To sum up, the instrument can accomplish the following testing tasks: 1. Conducting the sound wave measuring holes (diameter of about φ44mm and hole depths of 4 to 6 meters) arranged around the underground cavern
