一、无汞差压计概述原CF型浮子式差压计改装成无汞差压计,它是利用铜波纹管或橡胶波纹管隔离被测介质去掉水银的,所以自命名为“CB型无汞差压计”或“CJ型无汞差压计”。CB、CJ型无汞差压计,是在原CF型浮子差压计的基础上改装成的无汞差压计。因原CF型差压计是用水银作为仪表隔离被测
First, the overview of mercury-free differential pressure gauge The original CF float-type differential pressure gauge into a mercury-free differential pressure gauge, which is the use of copper bellows or rubber bellows to remove the measured medium to remove mercury, so named “CB type Mercury-free differential pressure gauge ”or“ CJ mercury-free differential pressure gauge ”. CB, CJ mercury-free differential pressure gauge, is based on the original CF-type float gauge pressure gauge into a mercury-free differential pressure gauge. Due to the original CF type differential pressure gauge is mercury as a measure of isolation
