ABSTRACT:
A precision measuring system of extraordinary accuracy particularly adapted to down-hole production logging tool strings. The disclosure emphasizes both compensating and immunizing error reduction means for hostile environments comprising varying line currents as well as large and rapidly changing ambient temperature extremes. Standard sensors and transducers are utilized, linearized, and error corrected. Calibration means permit outputs in familiar engineering units and scales. Accuracy exceeds .+-. 0.4% of full scale or, in the case of temperature measurements .+-. 1.degree.F from 50.degree.F to 300.degree.F.
