What does the range ratio of an intelligent transmitter mean? I saw 100:1 in a book – what does 100 refer to, and what does 1 refer to? Thank you
The range ratio is the ratio of the maximum measurement range to the minimum measurement range. A larger range ratio provides more room for adjustment; it enables the measurement range of the transmitter to be changed more easily when process conditions change, without the need to replace the instrument. It also helps reduce the number of instruments in stock, facilitating management and preventing capital stagnation. Therefore, the range ratio of a transmitter is a very important technical parameter.
As a supplementary note, the maximum and minimum measurement ranges are determined with the aim of ensuring measurement accuracy
