Help needed regarding temperature measurement and weight measurement
Thread Content
Regarding the use and selection of thermocouples and thermal resistors: for a measurement range of 0–150°C, one must decide whether to use a Pt100 or Pt50 thermal resistor, or a thermocouple of a certain type. Whether the measurement terminal is grounded or not also matters; each option has its advantages and disadvantages. The main considerations are measurement accuracy and ease of maintenance. For the packaging of liquids, it’s necessary to decide on which brand and model to choose for everything from the valve heads and solenoids to the sensors. It mainly features stable operation and simple maintenance. Try to choose well-known brands; you can suggest a few more options. Experienced people say, It’s exactly what we need! !
1 Generally, thermistors are used for temperatures below 200°C, while thermocouples are used for temperatures above 200°C (since thermocouples and thermistors respond differently to different temperatures). 2 Selection based on measurement accuracy: Choose a thermal resistor for higher accuracy requirements, and choose a thermocouple for lower accuracy requirements ； 3 Selection based on the measurement range: Thermocouples generally measure the temperature at a “point,” while thermal resistors typically measure the average temperature in a space.
