Selection of accuracy grade of pressure gauge

Issuing time:2019-10-22 00:00

According to the maximum absolute error allowed in the process production and the most distance of the selected instrument, the maximum reference error allowed by the instrument is calculated, and the accuracy of the instrument is determined in the precision level specified by the state. Generally speaking, the more precise the instrument is, the more accurate and reliable the measurement results will be. But we can't think that the higher the accuracy of the instrument is, the better it is. Because the more precise the instrument is, the more expensive the price is, the more difficult it is to operate and maintain it. Therefore, on the premise of meeting the process requirements, instruments with low accuracy, low price and durable should be selected as far as possible.压力表厂家 布水器 软水机厂家
