1.3.5 Gassing Point Assembly
The Gassing Point Assembl assembly can be fixed in a
convenient position and permanently connected by suitable
tubing to an inaccessible sensor, thus simplifying the
application of test gas when checking sensor calibration. A
DIN Rail Mounting Assembly (00785-A-0069) is available to
enable five gassing point assemblies to be mounted side by
side.
1.3.6 Hydrophobic Barrier
The Hydrophobic Barrier consists of a layer of stainless
steel mesh with a rubber rim. A hydrophobic barrier of PTFE
is bonded to the stainless steel surface.
This MUST be fitted with the white surface faceing outwards.
