What level of accuracy is required for the pressure transmitter |
The accuracy is determined by factors such as nonlinearity, hysteresis, repeatability, temperature, zero offset scale, and temperature effects. However, it is primarily influenced by nonlinearity, hysteresis, and repeatability. Higher accuracy generally leads to higher costs. Every electronic measuring device has inherent accuracy errors, but the stated accuracy levels vary by region. For instance, China and the U.S. typically define accuracy based on the sensor's linear region with better performance, which corresponds to the commonly referred range of 10% to 90% of the measurement span. In contrast, European standards define accuracy based on the sensor's least linear region, usually the 0% to 10% and 90% to 100% sections of the measurement range. For example, a European accuracy rating of 1% would equate to a Chinese rating of 0.5%
