FIELD: instrument engineering. ^ SUBSTANCE: invention concerns measurement equipment and can be used for profiling and engineering measurement of thermal field on specified surface generated from environmental impact of a distributed ignition source. A digital temperature metre incorporates N temperature sensors, hardware-software channel-forming modules and a metering unit comprising a N-channel synchronous analogue-to-digital converter, a microcomputer, a supervisor program, a nonvolatile rewriteable memory unit, a clock frequency generator, a digital transceiver, a hardware-software internal power voltage control module, a COM-port, an environmental data metering unit and a reference voltage source. ^ EFFECT: design of the self-contained easy-to-use digital temperature metre, profiling of thermal field and engineering measurement of thermal field with required accuracy on specified surface within desired time when exposed to the distributed ignition source. ^ 1 dwg |
