RIKA RK900-10
RK900-10
A weather instrument measuring wind speed and direction, air temperature, relative humidity and air pressure, with GPS and an electronic compass included. This configuration includes anti-corrosion marine treatment, RS232 output and a 10 m cable.
Measurement parameters and specifications
The table covers only the sensors included in this configuration supplied by Kordil. Performance figures follow the technical sheet for this model.
| Parameter | Principle | Range | Resolution | Accuracy |
|---|---|---|---|---|
| Wind speed | Ultrasonic | 0–60 m/s | 0.01 m/s | ±2% FS |
| Wind direction | Ultrasonic | 0–360° | 1° | <3° |
| Air temperature | MEMS | −40 to +80 °C | 0.01 °C | ±0.5 °C |
| Relative humidity | MEMS | 0–100% RH | 0.1% RH | ±3% RH |
| Air pressure | MEMS | 300–1100 hPa | 0.1 hPa | ±1 hPa |
| Position and speed | GPS | — | — | — |
| Heading | Electronic compass | — | — | — |
FS = full scale; RH = relative humidity. —: Not specified in the technical sheet for this model.
GPS and an electronic compass are included in this configuration. Position, speed and heading data support true-wind calculations on moving platforms; true wind is a calculated output. The technical sheet does not provide numerical resolution or accuracy for these components.
