The automatic tester is characterized by comprising a thermocouple temperature sensor, an amplifying circuit, an A/D converter, a single chip microcomputer, an LCD, a button and a serial port output. The amplifying circuit is connected with the thermocouple temperature sensor, the A/D converter and the single chip microcomputer, and the A/D converter, the LCD, the button and the serial port output are connected with the single chip microcomputer. The temperature display instrument can display measured temperatures of various thermocouples.
Description
Technical field
The present invention relates to a kind of temperature display meter, particularly a kind of electric thermo-couple temperature auto testing instrument.
Background technology
Thermocouple temperature measurement application is very general, but wide in variety due to thermopair, and the instrument of displays temperature needs corresponding with the model of thermopair, this can only show with regard to causing Displaying Meter the temperature that with it corresponding thermopair records, not only cause the waste of instrument resource, also because Displaying Meter is made troubles to operating personnel too much.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can support the use thermometric instrument with multiple thermopair.
For achieving the above object, the present invention is realized by following technical scheme:
A kind of electric thermo-couple temperature auto testing instrument, it is characterized in that, comprise thermocouple temperature sensor, amplifying circuit, A/D converter, single-chip microcomputer, LCD display, button and serial ports to export, described amplifying circuit is connected with thermocouple temperature sensor, A/D converter and single-chip microcomputer respectively, and described A/D converter, LCD display, button export with serial ports and be connected with single-chip microcomputer respectively.
Further, described thermocouple temperature sensor, comprises platinum rhodium 10-platinum thermocouple, nickel chromium-nickel silicon thermocouple, nickel chromium triangle-CopperNickel thermocouple.
Further, the model of described amplifying circuit is INA114.
Further, the model of described A/D converter is ICL7135.
Further, the model of described LCD display is LCD1602.
Principle of work of the present invention: temperature signal is converted to a millivolt voltage by thermocouple temperature sensor, the 1-5V DC voltage of outputting standard after amplifying circuit amplifies, single-chip microcomputer is delivered to after being changed by A/D converter again, Micro Controller Unit (MCU) driving LCD shows indicated temperature, button is used for operation setting, as arranged the type of thermopair, Temperature displaying scope and warning bound etc., serial ports exports and is used for and the communicating of computing machine.
The invention has the beneficial effects as follows, provide a kind of temperature display meter that can show multiple thermocouple temperature measurement.
