TPK-04L, TPK-04LS K Type Temperature Thermocouples Product ID: TPK-04L, TPK-04LS

Type K (chromel–alumel) is the most common general-purpose thermocouple with a sensitivity of approximately 41 µV/°C.It is inexpensive, 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. One of the constituent metals, nickel, 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, which occurs for type K thermocouples at around 185 °C.

How to use Surface temperature thermocouple correctly?

 

  1. The Objective surface should be kept clean, as a result of oil, dust, or other insulating material. For example,  paint will affect the measurement accuracy .
  2. Measured surface should be flat, For example,  the measured object is rough or uneven, you need to use grease ,smear on its surface.to get better heat transmitting. 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. Prohibit using surface thermocouple for rolling objects. Suggest to use scroll wheel temperature measurements Tecpel TPK-06 Rolling thermocouple to measuring rolling objectives.
  5. Take the vertical angle of 90 ° degrees.  The error should not exceed 5 ° degree angle to ensure the accuracy of temperature measurement
  6. 6. Do not measure the temperature exceeds its rated temperature, to avoid the thermocouple from being damaged.
