Rika Sensor RK120-07 Ultrasonic Wind Speed and Direction Sensor
Product Usage Instructions
Mounting & Dimension
- To mount the RK120-07 Ultrasonic Wind Speed & Direction Sensor, refer to the provided dimensions. Ensure proper installation for accurate measurements.
Equipment Maintenance & Attention
- If maintenance is required, lightly scrub the instrument with a cloth and soft detergent. Avoid using dissolvable reagents. Ensure proper cable connections and shield maintenance to maintain electromagnetic compatibility.
Installation Tips
- Avoid installing near radar scanning devices and turbulent areascaused by surrounding buildings. Install the sensor on the side of prevailing wind for optimal accuracy. Ensure proper power supply during operation.
RK120-0 7 The wind speed and direction meter are a kind of measuring instrument that uses the time difference of ultrasonic wave in the air to measure the wind speed and direction. RK120 07 uses low power chip with power consumption of only 0.2W, which is especially suitable for solar or battery-powered environments with high power consumption requirements. Due to the adoption of new technology and new process, the structure is more compact and compact. Optional temperature and air pressure module

DIMENSION
Step1:
- Positioning: Generally, RK120 07 is installed in a vertical installation pipe. ensure the measurement is on the same level.
- For indoor use, the sensor can be used anywhere. Directional installation to measure wind speed on different planes
Step2:
- There are rotary adjustable mounting holes at the bottom of the sensor. when mounting the sensor to ensure the indicator on the sensor comply with the geographic north
Step3:
- Installation: the installation pipe needs 3 equally spaced holes, tapping M5 screws, position7.5mm from the top of the pipe.
EQUIPMENT MAINTENANCE ATTENTION
Equipment maintenance:
- If there is dust on the instrument, it can be lightly scrubbed with a cloth st ained with (biodegradable) soft detergent.
- Do not use dissolvable reagents. Scrub carefully to avoid scratching the surface of the instrument. If there is snow or ice on the surface of the instrument, wait for it to dissolve naturally slowly, and do not us e tools to remove it.
Attention:
- Do not install it on the same plane with any radar scanning device, and keep a distance of at least 2m
- If the cable is not properly connected after cutting, or the cable shield is not well maintained, EMC (electromagnetic compatibility) may be reduced
- Ensure the continuous power supply of RK 120 0 7 in operation.
- Avoid turbulence caused by surrounding buildings, such as trees, power poles, tall buildings, etc., which can affect. The accuracy of acoustic wind speed a nd direction detector is affected. The detector is best installed on the side of prevailing wind.
- If it is installed on the building, theoretically, the installation height of anemometer should be 1.5 of the building heights
- RK 120 0 7 can meet or even exceed the specifications listed in it, and can be used in environments around the world without calibration
