Working principle
Frequency modulation continuous wave (FMCW) technology is adopted in the object level meter of 80GHz radar level transmitter. The continuous wave with frequency variation is transmitted within a certain period, and the echo reflected by the object has a certain frequency difference with the transmitted signal. The distance information between the target and the radar can be obtained by measuring the frequency difference.
Radar level meter, as a new industrial level measuring instrument, has the characteristics of high temperature resistance, high pressure resistance, vacuum resistance, strong penetration, temperature, steam, dust and other effects.
Applications
This 80GHz Radar Water Level Sensor has been specially developed for the needs of the water/wastewater industry, The super lightweight (0.35kg) and fittings can be selected as needed and only require minimal effort to install. This end-to-end concept allows simple integration and fast maintenance – it also reduces spare parts inventories and production downtime.
80GHz Radar vs. Ultrasonic
When it comes to non-contact level measurement, both Ultrasonic and Radar are two of the most common types, while radar is divided according to a different frequency, namely: 26GHz, 80GHz, 120GHz. Those devices applied similar measuring principles, installation(from top to end), and for dealing with similar industrial applications. Each technology has varying degrees of success in different applications.
Ultrasonic level instrumentations are a cost-effective devices, which is suitable for some simple applications, but they’re not as reliable or accurate in changing or difficult environments. Most application don’t have the stationary product in a stable condition, it will be wise to select 80GHz radar over an ultrasonic device.
