The fundamental purpose of this investigation was that of developing a temperature measurement system that does not have contact with the process of interest, by means of the use of a sensor of infrared temperature. Among the specific objectives they are found: to understand the principle of operation of the measure of temperature through infrared energy, characterization of the sensor, design of the circuit electronic conditioner of the sign, being arrived al complete development of the design of the electronic circuit (hardware and software) where the fundamental elements of this system of measure be established. It investigation was experimental of laboratory, being employed like data harvesting instruments the observation, the documentation. The errors obtained in the system of measure do not surpass the 0,4 %, and in the case of the error of zero resulted of 0,1 %. The error of not linearity did not surpass the 0,5 %. The result of this investigation represents a first approximation to a prototype of instrument for the measurement of temperature through the infrared energy, without there be contact between the sensor and the process of interest
