FIELD: physics, instruments. ^ SUBSTANCE: said utility invention relates to electric metering equipment and is intended for high-speed simulation of the discrete signal of temperature sensing generating transducers (e.g., thermocouples) during automation of the metrological research of quick-acting instruments and systems in the electric thermometry. The invention aims at providing the possibility to automate the process of metrological control of instrumentation, decreasing the manufacturing and maintenance costs, decreasing the manufacturing costs, eliminating the need of regular replacement of components, decreasing the dimensions and weight significantly. This aim is achieved because the thermocouple signal simulator contains resistance divider with output drops, Zener diode connected to the resistance divider input, common bus current generator connected to one input pin of the resistance divider, and common bus operational amplifier. The output of the amplifier is connected to the other input pin of the resistance divider, the uncomplemented input of the amplifier is connected to the common bus, and the complemented input of the amplifier is connected to one output drop of the resistance divider. ^ EFFECT: provision of possibility to automate process of metrological control of instrumentation, decrease in manufacturing costs, instrument dimensions and weight. ^ 1 dwg |
