Preliminary Temperature Measurements in Cornwall

Abstract

As part of a mineral exploration feasibility study in marine areas near the coastline of Cornwall, equipment has been constructed for the measurement of temperature to a sensitivity of 0.01° C. The temperature-sensing element is a thermistor, mounted in a probe, connected via long leads to a bridge/amplifier circuit where the determination of the variation of resistance with temperature can be made. The circuit is so arranged that compensation is provided for the lead resistances.
