Pyrometer for temperature measurement

摘要

The invention relates to a pyrometer for temperature measurement which is to be applied in process and industrial measurement technology. The aim and object of the invention are to provide a pyrometer for temperature measurement in which the production costs are reduced, the operating functions are minimised and the range of use is extended, and to permit the pyrometer according to the invention, which is to have a robust and simple design, to measure the temperature of a test material of known emittance with a high measurement accuracy and in conjunction with a short response time. The essence of the invention consists in that via an optical system the pyrometer focuses the thermal radiation emanating from the test material onto a device and directs it onto three detectors downstream of which there are respectively connected logarithmising networks which, for their part, are connected to a summation network which is connected upstream of a voltage divider connected to a delogarithmising network at whose output a transducer is located and a temperature display may be connected. The field of application of the invention is process and industrial measurement technology. The patent specifications specified deal with the measurement problem and have been selected for this reason. <IMAGE>
