Intelligent resistive temperature sensor

An analysis is made of the currently existing methods of metrological self-validating of resistive temperature sensors, which make it possible to control the change in the metrological characteristics of the resistive temperature detector (RTD) and thereby evaluate the reliability of the information transmitted by the sensor. An intelligent resistive temperature sensor using the self-heating of the vehicle due to the flowing current for a fixed time is proposed. The difference in the measured values of the RTD resistance before and after self-heating is used to judge the error in measuring the temperature by the sensor that occurs due to external conditions and aging of the RTD. Prototypes of an intelligent temperature sensor were manufactured. An experimental study of various types of RTDs was carried out: copper wire TSM-100 and platinum TSP-100, thin-film platinum Pt-100. The change in resistance of Pt-100 during self-heating is an order of magnitude higher than the similar change in resistance of TSM-100 and TSP-100, therefore, studies with RTD aging were carried out only with Pt-100. An artificial change in the metrological characteristics of RTDs was achieved due to accelerated aging of RTDs by establishing high temperatures for a certain time. Experimental studies have shown that the proposed intelligent temperature sensor allows not only to evaluate the change in the metrological characteristics of the RTD due to environmental influences and aging, but also to correct the appearing error of temperature measurement under certain conditions.

Keywords: metrological self-validating, self-heating, resistive temperature sensor, intelligent sensor.

Air humidity consideration at calibration critical nozzles for gas flow measurement

The experimental results of the dependence of air volume flow rate through critical Venturi nozzles vs. the air humidity at atmospheric pressure are presented. The results were obtained by calibration of five critical nozzles (with nominal flow rates from 2 to 50 m3/h) on a bell-type reference rig as part of the State Primary Standard of Volume and Mass Gas Flow Rate Units GET 1182017. It has been established that the method of A. Aschenbrenner is expedient to be used for determination the coefficient of humidity influence for given operating and design parameters.

Keywords: critical flow nozzle, calibration, air humidity, gas flow rate, discharge coefficient, measurement standard.
