Maintaining the Dwyer 641 Air
Velocity Transmitter
The AVT probe will collect dirt and dust from the air stream. It needs to be
cleaned at least once a month. To clean the probe:
1
Switch the blower to “Manual” on the Dehumidifying Dryer Screen
(Screen 4) and input the proper percentage setpoint to maintain the prop-
er air flow,
before you remove the probe from the pipe.
2
Mark the depth that the probe is inserted into the pipe, for reinstallation.
3
Observe the percentage of drive speed on the Dehumidifying Dryer Screen
(Screen 4)
before you switch to manual. Once you switch to manual input, this
number turns into the setpoint %.
4
Remove the AVT probe from the pipe and clean it with a Q-tip and
denatured alcohol.
Use care when cleaning so you do not damage the
measuring element in the probe.
5
Reinstall the air velocity probe back into the pipe. Make sure it is installed
at the same depth and air flow direction. (Note flow arrow.)
6
Switch the blower to “Auto”on the Dehumidifying Dryer Screen (Screen 4)
if desired.
