Abstract

System for measuring and recording data in probes to provide output voltages that correspond to at least one parameter measured in a probing hole, which comprises a measurement and data recording instrument that includes a pickup device adapted to travel through the drilling holes and conductive means connecting said pulse output device of the measurement and data recording instrument to the electronic equipment located on the surface near the drilling hole to transmit the output pulses from the measuring and recording instrument of data to electronic equipment located on the surface; characterized in that the data recording and measuring instrument includes at least two means for detecting one or more parameters in the probing hole, each detector device providing a signal representative of the measured parameter, and a pulse output device connected to the device detector for providing output pulses of opposite polarities corresponding to the respective detector devices; and in that said electronic equipment located on the surface includes a receiving means connected to the conductive device to receive the output pulses transmitted from the conductive device, and a treatment connected to the receiving device for the received output pulses according to their polarity, in order to obtain first and second outputs respectively representative of the parameters measured by the corresponding detector device.
