Air Velocity Transmitter The Series 641RM 16 field Air Velocity transmitter selectable reaches from 0-250 to 15,000 FPM (0-1.25 to 75 MPS) give it the flexibility to be chosen for a large number of uses. The unit’s 6′ link which associates the detecting test with the electronic fenced in area enables the walled-in area to be mounted where it very well may be all the more effectively got to. Longer link lengths are accessible for channels that are at high heights from the plant floor. The discretionary LED creates an entire, conservative answer for a nearby sign of wind stream.
