 Alnor models AVT 55, AVT 65, and AVT 75 Air Velocity Transducers provide the flexibility needed for air velocity measurements in research and development labs, manufacturing processes, and other applications. They are ideal for both temporary and permanent installations. Three models each incorporate a different sensor configuration and are available with a standard 12 inch probe or three shorter probe lengths. The full-scale range, signal output, and time constant are user-selectable and can be easily changed to meet the needs of your application.
The general purpose AVT 55 has a protected tip, a rugged ceramic sensor, fast response time, and a wide velocity range. The windowless probe design of the AVT 65 makes it ideal for use in confined spaces where a large probe would block the flow. The omni-directional AVT 55 is accurate at very low velocities and ideal for use when the flow direction is unknown.
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 dataloggers or data acquisition systems. In addition, the current and voltage output ranges are user-selectable for your convenience.
