Make sure there is a minimum clearance of 5 m (16.5 ft) between the
probe body and any possible humidifier. Avoid installing in a location where
condensation can fall on the sensor inside the duct.
2
When installing the transmitter, drill a second hole approximately 30
cm (12 in) from the installation hole, towards the direction of the air flow, and plug
it with a removable seal. This second hole is intended for later use in reference
measurement with another device when calibrating or adjusting the transmitter.
3
Check that the duct diameter is suitable for the probe body (see Transmitter Dimensions). Ideally, the sensor (probe head) should be installed in the middle
of the duct.
4
Maximum air flow speed: 50 m/s (with sintered filter).
5
Avoid installing the transmitter in dead legs. Supersaturation can
occur in areas where there is no air flow.
6
Do not install the probe in a downward angle. Condensation can travel to the sensor along the probe body if the probe points down.
7
Install the probe in a 90° angle so that the sensor is placed as close to the middle of the duct as possible.
