DB  Acoustic Analyzer

DB series (DB4, DB8, DB16) type multi-function acoustic meter is designed in line with the three aspects of new idea,theory,method,and technology of full wave seismic phase analysis, ultrasound earthquake model test, rock comprehensive physical property test, which are comprehensive used in solving engineering survey questions and uniform rock,soil,concrete structure and construction quality testing problems.The main features are with three component or more components piezoelectric transducers, multichannel,broadband,high sensitivity, microprocessor control and all wave train recording more waves and shocks. The instrument is high speed,multichannel,once or continuous connection, that can be used for well logging,loose circle,measuring the pile,highways,tunnels,bridges and indoor rock,ultrasonic earthquake model test. With super magnetic flex emissivesource and transducer can realize continuous emission, power similar to electric spark emissive power, while frequency can reach 8KC. It can proceed indoor,outdoor acoustic emission, 16 route shallow earthquak test. Provide variety of methods for various occasions ordinary acoustic wave testing.

Host machine: 4 route 20MC high speed 8 digit A/D conversion. 12,16 route 20MC high speed 10 digit A/D conversion. The host is with 4,12 or 16 channel transient state collection, each channel 32KB RAM with high cut-off frequency and low cut-off freguency optional. The machine has 16V and 1KV emission function, can connect super magnetic flex emissivesource etc.
