Quick Overview

The AV-DSP 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). A standard Insertion length of up to 240mm and probe diameter of 19mm, the AV-DSP will fit in a wide variety locations. Using the hot-wire method of airflow measurement, the AV-DSP needs no maintenance.
