| Abstract: | The data processing interface of voltage interface mud logging unit is composed of analog boards, this interface matches voltage sensor, but it isn't compatible with current sensors. Through analyzing original interface circuit, the paper set forth practical improvement method for application of the current sensor to this kind of mud logging unit, therefore, the whole properties of the unit will be strengthened greatly and it has a certain guiding value in using and maintaining voltage interface mud logging unit. |
