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.
