system, a turn-key system containing data acquisition and control
instrumentation, a sample pump, and optional zero-and-span valve module.
The EC155 vortex sample cell and the new CSAT3A sonic head (denoted by
EC155 sample cell and CSAT3A serial numbers 2000 and greater) became
available in January 2016. The EC155 has the following enhancements:
•
A vortex intake (U.S. Pat. No. 9,217,692) significantly reduces
maintenance frequency, especially in dusty or polluted conditions, and
preserves high frequency response over time
•
A heated inlet and elimination of the inline filter results in increased
condensation protection while better maintaining frequency response
over time
•
More accurate sample-cell pressure measurements are made possible
with an absolute pressure sensor in the sample cell
•
The new intake remains fully integrated but may be detached or
replaced if needed
•
Stainless steel sample cell for increased corrosion protection
The new version (top panel) and old version (bottom panel) of CSAT3As are
shown in FIGURE
. The new CSAT3A design also has important new
features:
•
Increased rigidity of the CSAT3A improves long-term accuracy and
stability of sonic temperature measurements
•
A more streamlined and aerodynamic CSAT3A mounting block
