CSAT3B Three-Dimensional Sonic
Anemometer
1. Introduction
The CSAT3B is an ultrasonic anemometer for measuring sonic temperature
and wind speed in three dimensions. The CSAT3B can measure average
horizontal wind speed and direction, or turbulent fluctuations of horizontal and
vertical wind, and sonic temperature. Further, momentum flux and sensible
heat flux can be calculated from the turbulent wind and sonic temperature
fluctuations. Latent and sensible heat flux and gas fluxes may be determined by
computing the covariance between vertical wind measured by the CSAT3B and
scalar quantities measured by other appropriate sensors.
Before attempting to use or install the CSAT3B please review:

2. Precautions
•
section at the front of this
manual.
•
CAUTION
o
Voltage input must be within range of 9.5
−
32 VDC
o
The CSAT3B head should be handled by holding the block at the back
of the sensor. Handling it by the arms or transducers could cause
geometric deformation, which degrades the measurements.
o
The transducer faces are fragile. Care should be taken to avoid
scratching or rubbing the surface of the transducer.
o
Grounding the CSAT3B is critical. Proper grounding to Earth will
ensure maximum electrostatic discharge (ESD) and lightning
protection and improve measurement accuracy.

IMPORTANT
o

3. Initial Inspection
Upon receipt of the CSAT3B, inspect the packaging and contents for damage.
File damage claims with the shipping company. Contact Campbell Scientific to
facilitate repair or replacement.
Immediately check package contents against shipping documentation.
Thoroughly check all packaging material for product that may be trapped
inside. Contact Campbell Scientific about any discrepancies. Model numbers
are found on each product. On cables, the model number is often found at the
connection end of the cable. Check that correct lengths of cables are received.
