The dynamic parameters of micromechanical thermo-resistive directly heated converter are measured in different mediums. The hardware architecture of the designed automated stand on the base of the hardware-software complex NI Elvis II, software and user’s interface into LabVIEW environment are described. The results of thermo-resistive transducer’s characteristics measurement, received with theproposed stand, have analyzed

An expression for the dependence of the resistance of the sensing element is presented primary transducer on oxygen concentration The structure and software of the created experimental setup are described. Analyzed experimental results of the study of the dependence of the resistance of the sensitive element of the thermomagnetic sensor oxygen on the concentration of O2 in the gas mixtures for different tension values magnetic field and dissipated power on the sensing element
