Intelligent pressure module
的特点： Features of the intelligent pressure module :
The smart pressure gauge has a compact and firm external structure, integrated packaging, and good performance.
Unified standard signal transmission, which can be connected with any of the company's digital pressure gauges to achieve range expansion.
The intelligent pressure gauge module has a built-in CPU, 24-bit A / D, and continuous correction of temperature drift to ensure the accuracy and reliability of the output signal.
The module's long-term stability (time drift) can be timely corrected by the host to ensure the accuracy of the meter for a long time. Model selection of intelligent pressure module method name model range resolution accuracy
选择方法 Intelligent pressure module selection method
First of all, the customer must confirm clearly that the maximum pressure range Pmax, the minimum pressure range Pmin, the accuracy of the test meter △, the pressure module accuracy △ module in the existing pressure instrument:
According to the standard table accuracy, which is 1/4 of the measured value's accuracy transfer relationship, to calculate the pressure module range to cover the measured table multiples n; n = △ tested / (△ module × 4)
量程如下选择： The range of the intelligent pressure module is selected as follows:
The first pressure module range P1 must select Pmax, that is, P1 = Pmax. The range that the first pressure module P1 can cover to the meter under test is P1 / n
The range of the second pressure module P2 should be the next range of the meter under test; P2 can be covered by the second pressure module P2.
The range of the third pressure module P3 should be the next range of the meter under test; P3 / n can be covered by the third pressure module P3
The range of the fourth pressure module P4 should be the next range of the meter under test; P4 / n can be covered by the fourth pressure module P4
Until the minimum range Pmin of the meter under test is covered.
