Abstract

Abstract

A platinum thermometer suited for measuring the temperature of sea water is described.Two platinum resistors are used as temperature-sensing elements in a symmetrical Weston's bridge.The results of measurement are displayed digitally with an accuracy < ±0.05℃ in the range -5℃-+35℃.Theoretical analysis and error estimations are made in detail and experimental results are given as well.
