Its circuits communicate with telemetry/GR tool by Ethernet, receive the command from NTGR tool, digitalize the received waves, and up transmit them to the NTGR tool. Sonic array adopts one transmitter and five receivers. ReceiversR5, R4, R3, R2 are used to measure sonic speed, and R5 and R1 measure CBL and VDL to complete borehole compensated sonic△T measurement, providing sonic speed curve for formation comparison, calculating formation porosity. It can also be used in the cased hole for sonic amplitude logging to provide quality information of cement bonding, the CBL.

It is composed of electric circuit and sonic sonde(3’-6”-6”-6”-6”-6”). The circuit housing is made of PH stainless steel.
