Three types of temperature measurement can be realized. The needs of different measurement ranges, different measurement accuracies and different occasions can be met.

Description

technical field [0001] The invention relates to a temperature data collector, in particular to a temperature data collector capable of meeting different measurement ranges and different measurement precisions. Background technique [0002] At present, the measurement range, measurement method and measurement accuracy of most temperature collectors in the market have been fixed when they leave the factory. The measurement method is single, the measurement range is fixed, and the sensing method can only be adapted to certain occasions. Therefore, it cannot be well applied to occasions with multiple measurement methods and measurement ranges. Furthermore, their measuring procedures and look-up table databases have been fixed, which cannot be applied to some occasions with special requirements. Contents of the invention [0003] The object of the present invention is to provide a temperature data collector capable of meeting different measurement ranges and different measur...
