Abstract

Different methods of construction of meters of temperature of a rail are considered. It is shown, that from the point of view of simplicity of building a system, it is most expedient to use an integral method of registration of temperature without application of shaping optics with a cooled infrared photodetector. It is noted, that the measurement of temperature of a rail with the help of infrared receivers MG-30 can be realized by two methods - method of direct measurement and substitution method. The feasibility of the infrared receiver MG-30 for construction of pyrometers on the known principles monochromatic, two-spectral, operating thermal contrast and integral is analyzed. For each method the influence of background noises is considered. It is established, that at restricted angles of vision of the meter in a situation of measurement of temperature of a rail the background noise is by an order less than the useful signal. By way of designing, it is established and experimentally confirmed, that the idea ofcreation ofa pyrometer on base MG-30 is quite realizable.
