Abstract

There is a problem of characteristics perfection of measurement means due to the appeared computing opportunities and with wide use of microprocessors in measurement means. The creation of measurement means with an estimation of own condition during work, including independent calibration and graduation is the most perspective direction of this development today. The design and a work principle of a selfcalibrated temperature sensor is offered on the basis of melting points.
