AV-622 Single-Point Multi-Range Air Velocity Transmitter

Quick Overview

The AV-622 is a single point, insertion, air velocity transmitter with user selectable 0-10vDC or 4-20mA outputs and 4 user selectable measurement ranges (0-4m/s, 0-8m/s, 0-16m/s or 0-32m/s). The unit requires a 12-35vDC power supply and has an Insertion length of up to 215mm and probe diameter of 19mm. A flange plate (DPA) is available for adjustment of the penetration depth. The unit has a built-in self test feature and the user can manually override the output to 0%, 50% or 100% of output range to aid commissioning. The enclosure has a snap-shut lid with an IP54 rating but can also be secured with screws to achieve a better IP65 rating.

The AV-622 replaces the AV-DSP air velocity transmitter
