Our standard pressure sensor is a Setra 278. Pressure sensors are generally mounted in the logger enclosure along with a moisture resistant breather to ensure pressure equalisation.
Humidity & Temperature
For a complete picture of a site's wind climate, both humidity and temperature are generally recorded. WMI recommend the rugged calibrated Hygroclip which can be supplied with a heater option to minimise saturation recovery. The sensor is mounted in a radiation shield at the height you require.
In situations where only temperature is required we generally recommend a BetaTherm 10K3A11B Thermistor plus radiation shield.
