Further, described temperature sensor (1) adopts K type thermopair, and its diameter of section is 1mm; And the collector interface (307) of described collector (3) is connected to by connecting line (101).
Further, described data bus (2) is RS485 data bus.
Further, described transacter (4) is industrial computer or computer.
The beneficial effects of the utility model: the built-in integrated temperature sensor that 1, collector is built-in and built-in single-chip microcomputer carry out temperature self-compensation correction data error, avoid affecting by ambient temperature causing measuring tempeature to occur comparatively big error.
That 2, comes up due to temperature sensor collection is micro voltage signal (about tens mV), so each passage is containing signal amplifier, and consider its fault in enlargement, be finally amplified to the standard voltage signal transmission of 0-5V, data reliability, stability are higher.
3, adopt the corresponding sensor of a passage to carry out AD conversion respectively, branched sensor synchronous acquisition can be realized, real-time accurate recording temperature data.
4, because thermopair quantity is many, a corresponding sensor of passage, has an absolute address separately, just in case thermopair has indivedual if any damage, directly can show problem sensing station from main frame.Be convenient to maintenance and later maintenance in time.
