Description

Technical Field

[0002] The gas-to-electric converter is a unit module that accurately and quickly converts the air pressure change signals of various detection parameters of the pneumatic detection device into DC voltage signals and digital signals. At present, the gas-to-electric converter has two precision gas flow adjustment knobs. When in use, the operator needs to adjust the flow first. The flow adjustment requires repeated adjustment of the two gas flow adjustment knobs so that the output flow is within the linear segment of the gas-to-electric converter before it can be used. Because the flow adjustment needs to be in a certain order, the two gas flow adjustment knobs need to be repeatedly adjusted many times to meet the requirements. At the same time, the operator needs to have certain usage experience, otherwise it is difficult to find the optimal linear segment. At the same time, the gas-to-electric converter currently only has a DC voltage signal output, and users need to perform an A / D analog-to-digital conversion again, which increases the user's cost. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Utility Model Content
