Abstract

This paper introduces a research methods of platinum thermal resistance signal conditioning module to long distance temperature measuring instrument. Mainly used ADT70 to turned the PT1000 platinum resistance temperature sensor resistance change when the temperature change into a voltage signal output., And design the hardware circuit from several aspects, such as the lower cable interference and low power consumption, etc. This design can be used in underground water well water temperature measurement temperature measuring work and already be applied in 100 meters of temperature measurement range.
