ABSTRACT:
A well logging tool adapted for use in a borehole traversing an earth formation includes at least one sensor sensing at least one characteristic of the earth formation. Another sensor senses the ambient temperature and provides a corresponding temperature signal. An output circuit provides a temperature compensated output signal corresponding to the sensed characteristic of the earth formation in accordance with the temperature signal and the characteristic signal.
