Working condition of micro thermocouple

The two ends of the conductors of different components are welded to form a loop. The direct temperature measurement end is called the working end, and the terminal end is called the cold end, also called the reference end. When there is a temperature difference between the working end and the reference end, thermal current will be generated in the loop. Connect the display instrument, and the instrument will indicate the corresponding temperature value of the thermoelectromotive force generated by the thermocouple.

Temperature unit of micro thermocouple

Temperature unit: Thermodynamic temperature is a basic physical quantity. Its unit Kelvin is defined as 1/273.16 of the thermodynamic temperature of the triple point of water. The difference from 273.15K (freezing point) is used to express the temperature, so this method is still retained. . By definition, the degree of Celsius is equal to Kelvin, and the temperature difference can also be expressed in degrees Celsius or Kelvin. The international temperature standard ITS-90 defines both the international Kelvin temperature (symbol T90) and the international Celsius temperature (symbol t90).

Technical advantages of thermocouples

The thermocouple has a wide temperature measurement range and relatively stable performance; high measurement accuracy, the thermocouple is in direct contact with the measured object, and is not affected by the intermediate medium; the thermal response time is fast, the thermocouple responds flexibly to temperature changes; the measurement range is large, the thermocouple The temperature can be measured continuously from -40~+1600℃; the thermocouple has reliable performance and good mechanical strength. Long service life and convenient installation.

USB thermocouple input module

Connecting the new UTC-USB universal thermocouple connector to Omega is an easy way to convert the thermocouple signal and display the actual temperature on your PC by reading the standard USB port (the whole cable is provided).

　It is characterized by a patented universal input Omega connection, so you can quickly attach two standard and miniature thermocouple plugs.

　The discrete power unit accepts 8 different types and thermocouples to provide automatic cold junction compensation and linearisation. Free software is included, allowing you to choose the type and unit of thermocouple. You can use your computer, monitor, graph record and log temperature data.
