Thermocouple problem
Thread Content
Let’s ask a few tricky questions for everyone to think about: 1. After being used in an environment of 400 degrees for 3 years, will the zero point and temperature characteristics of the thermocouple change? How much will it change approximately? 2. Regarding the accuracy of thermocouples, is the highest accuracy for K-type thermocouples really +-1.5 degrees? 3. What is the price difference for B R S KT-type thermocouples of the same specification?
Let the technicians from the manufacturers that produce thermocouples come and give an answer.
The first-grade accuracy of a K-type thermocouple is 1.5 degrees.
1. After being used in an environment of 400 degrees for 3 years, will the zero point and temperature characteristics of the thermocouple change? How much will it change approximately? Answer: Over a long period of use and across a wide temperature range, thermocouples maintain stable temperature characteristics; however, their zero point may deviate, and they generally need to be calibrated once a year. 2. Regarding the accuracy of thermocouples, is the highest accuracy for K-type thermocouples indeed ±1.5 degrees? Answer: The highest precision of K-type thermocouples is ±1.5 degrees; the precision of such thermocouples can only reach ±1.5℃. 3. What is the price difference between BRSKT-type thermocouples of the same specification? Answer: As for the price, I know that K-type ones generally cost 400-600 yuan each
