			<description><![CDATA[@RIck Cantwell we use Omegadyne PX-309 transducers (http://www.omegadyne.com/ppt/prod.html?ref=PX309&flag=1) which employ the use of silicon strain sensors. The unit's temperature is well isolated from the rest of the cell's operating temp and typically couples well to ambient temperature cycling, though it's tough to observe in the current data. We've been entertaining the idea that we're paying too close attention to a pressure sensor with a limited resolution. Additionally it might not hold up well in a hydrogen atmosphere. Hydrogen diffusion through the silicon sensor membrane should be pretty poor, shouldn't it?]]></description>

			<description><![CDATA[Perhaps we could plumb a second pressure sensor into the line and monitor both of them. If the pressure drop is real, it will show up in both sensors. Otherwise it is probably a phenomenon inside the sensor.]]></description>
