What is the range ratio of a transmitter? What is its meaning?
The range ratio of a transmitter is the ratio of the maximum measurement range to the minimum measurement range. For example, for a pressure transmitter with a range of 0-10 KPa to 500 KPa, the range ratio is 50:1. It is said that high-quality transmitters can achieve a range ratio of 100:1. Its advantage lies in the wide measurement range of the transmitter; the upper limit can be as high as 10–500 KPa. Accuracy cannot be guaranteed below 10 KPa, so it should not be used in applications with pressures lower than 10 KPa. The range ratio is a reference indicator when purchasing transmitters, and it is worth paying attention to.
The range ratio of a transmitter refers to the ratio of the maximum value to the minimum value that can be measured by the transmitter while still meeting the accuracy requirements. Generally, the larger the range ratio, the lower the measurement accuracy. A pressure transmitter with a large range ratio has many advantages, as it can be used in various different applications after being calibrated. However, in practice, if the range ratio is set too high, it will cause many problems related to measurement stability
A larger range ratio means a wider range of applications; several different models can be chosen for one set of equipment to meet the requirements, which enhances interchangeability, reduces the number of spare parts needed, and lowers costs.
The range ratio is the ratio of the maximum measurement range to the minimum measurement range. A higher range ratio provides more room for adjustment, allowing the measurement range of the transmitter to be changed more easily when process conditions change, without the need to replace the instrument. This also helps reduce the number of spare instruments in stock, facilitating management and preventing capital accumulation.

The total range is 0-1000, with a range ratio of 100:1; in other words, the minimum applicable range is 10. However, the accuracy becomes quite poor when using a range of 0-10. The accuracy claimed by the manufacturer varies depending on the range ratio, with different formulas for calculating accuracy in such cases. The range ratio should not be too small
