TSI 8455-075-1 Airflow Air Velocity Transducer

For air velocity measurements in research and development labs, manufacturing processes, and other applications, the Air Velocity Transducer 8455 (general purpose) is excellent for both temporary and permanent installations. On-board electronics and calibration curves of the Model 8455 give a linear signal output. This linear signal can be delivered to a number of data loggers or data gathering systems as either a current (mA) or a voltage (V) signal. Best of all, the user can modify the current and voltage output ranges in under five minutes.

Ideal Applications include comfort and draft studies, critical environment installations (such as clean rooms and hospitals), diffuser design analysis, monitoring drying processes, monitoring air flows in tunnels and subways, used as a standard in wind tunnels and calibration facilities, environmental monitoring in greenhouses and IAQ applications, and general engineering applications are all ideal applications.
