It is advisable to mount the transmitter so that the pressure input is facing down-
wards, in order to reduce the accumulation of dust and dirt on the input.
For outdoor installation, the use of the transmitter version with static pressure port
(
BAROsense…K ) is recommended, in order to minimize the measurement error
caused by the wind flow on the pressure input (the measurement deviation due to
wind is less than 0.3 hPa @ 20 m/s if the static port is used). The transmitter version
with static port includes a support bracket suitable for fixing to a Ø30…50 mm mast.
