The oil/gas separation membrane used in gas sensor made by other manufacturers is very fragile and easy to damage in vacuum. Has the ASENSOR’s gas sensor been improved in this aspect?
Based on the statistics, roughly 80% of on-site fuel cell gas sensor malfunctions are caused by the damage of oil/gas separation membrane. The thickness of oil/gas separation membranes is a conflicting issue with its mechanical strength. A very thin membrane allows for quicker gas permeation which increases the sensitivity of gas sensor, but it is easy to be deformed or even damaged under pressure. The membrane can normally withstand positive pressure (because of the support behind the membrane), but becomes deformed under negative pressure or vacuum which leads to the loss of accuracy even malfunction of the sensor. The vacuum may be caused by a maladroit installation, transformer degassing, or large/sudden temperature change.The ASENSOR’s patented oil/gas separation membrane is born to solve these problems. It has the mechanical strength of a metallic material; while retaining the original gas permeability of the membrane. It allows the sensor for the first time in the world to withs
