Optimized, Low-Power Dissipative and Precise Pulsating Constant Current Source Based Temperature Measurement System
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
A constant voltage source based temperature measurement system; using PRT-1000 is one of the currently used methods to measure the temperature of subsystems in Indian Satellites. One such subsystem which uses PRT-1000 is solar panels. This paper describes a constant current source based temperature measurement system and the advantages it offers in terms of linearity, sensitivity and power dissipation. Simulations using MATLAB and Simulink® are carried out to illustrate the differences between the two methods. To overcome self-heating effects in the resistor a pulsating constant current source based temperature measurement system is described.
