TPK-04L, TPK-04LS K型温度热电偶 产品编号:TPK-04L, TPK-04LS

Type K (chromel–alumel) is the most common general-purpose thermocouple with a sensitivity of approximately 41 µV/°C.它是便宜的, and a wide variety of probes are available in its −200 °C to +1350 °C (−330 °F to +2460 °F) range. Type K was specified at a time when metallurgy was less advanced than it is today, and consequently characteristics may vary considerably between samples. 金属:构成金属的一种, 镍, is magnetic; a characteristic of thermocouples made with magnetic material is that they undergo a deviation in output when the material reaches its Curie point, K型热电偶在185°C左右会发生什么.

如何正确使用表面温度热电偶?

 

  1. The Objective surface should be kept clean, as a result of oil, dust, or other insulating material. 比如油漆会影响测量精度 .
  2. 测量表面应平整, 例如,  被测物体粗糙或不平, 你需要用油 ,涂抹在表面.以获得更好的导热性. Rough surface tends to cause the thermocouple sensor damaged or poor performance of  the accuracy .
  3. Measurement of surface area must be greater than the size of a probe sensor.
  4. 禁止使用表面热电偶滚动物体. Suggest to use scroll wheel temperature measurements Tecpel TPK-06 Rolling thermocouple to measuring rolling objectives.
  5. 取对顶角90度.  The error should not exceed 5 ° degree angle to ensure the accuracy of temperature measurement
  6. 6. 测量温度是否超过其额定温度, 避免热电偶损坏.
