Air Velocity Transducer TSI Model 8475
Features
Accuracy: +3.0% of reading2,
2From 68 to 78.8°F (20 to 26°C), outside this range and within temperature compensation
range add 0.28% per °F (0.5% per °C). Directional sensitivity of the Model 8475 is +5%/-20% of reading +0/-10 ft/min
(+0/-0.05 m/s) over 270° solid angle regardless of flow direction.

All models contain on-board electronics and calibration curves that provide a linear signal output. This linear signal is sent out as either a current (mA) or a voltage (V) signal, allowing output to a variety of data loggers or data acquisition systems. In addition, the current and voltage output ranges are user-selectable for your convenience.
