France LCJ Capteurs Anemometer Ultrasonic Sensor - CV7-E
Traditional anemometers have rotating mechanical parts. These moving parts are prone to damage the sensor. The ultrasonic sensor is designed
to avoid any mechanical parts to ensure more reliable operation. Ultrasonic sensors offer long-term stability without
maintenance.
Product Introduction
1. France LCJ Capteurs Anemometer Ultrasonic Sensor CV7-E Description:
Traditional anemometers have rotating mechanical parts. These moving parts are prone to damage the sensor.Ultrasonic SensorsIt is designed to avoid any mechanical parts to ensure more reliable operation. Ultrasonic sensors offer long-term stability without maintenance. Sound is transmitted by moving objects at intersections. Electroacoustic sensors (1) communicate with each other using ultrasonic signals (2) along orthogonal axes, where wind speed (3) causes differences in sound wave transmission time. The CV7 sensor transmits 4 different tests between them, and the headwind obtained from the tests is used for calculation. Combined measurements calculate wind speed and wind direction based on the base axis. Temperature measurement is used for calibration. The sensor design reduces the influence of tilt angle (4) (the effect of sensor tilt can be partially corrected due to the spatial shape of the sensor). CV7 transmits 4 independent test data. A correctness check is used for the calculation of the headwind vector. This method gives a wind speed sensitivity of 0.15 m/s and excellent linearity up to 40 m/s.
