Overview
A Pressure Node is a wireless node that measures air pressure differences between the
data center room and its subfloor cavities or overhead plenum environments. A
Pressure Node installation kit consists of the wireless pressure-sensing node and two
low-pressure air hoses fitted with diffusers. Each diffuser resides in a location to
measure the air pressure differential between the room and the subfloor or overhead
plenums.
Once installed and operational, the node transmits air pressure data to the Web
Console. Combined with other air pressure differential data collected from various
locations in the data center, operators use this information to adjust fan speeds and
relocate perforated tiles to increase CRAC/CRAH efficiency.
