TSI 8455 Air Velocity Transducer

TSI 8455 / 8465 / 8475 Air Velocity Transducer

The Air Velocity Transducers 8455/8465/8475 are ideal for both temporary and permanent installations for air velocity measurements in research and development labs, manufacturing processes, and other applications. The three 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. Best of all, the current and voltage output ranges are easily changed by the user in less than five minutes.
Ideal applications include comfort and draft studies, critical environment installations (eg, 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 as well as general engineering applications.
