6.8GHz Liquid Radar Level Transmitter IP67 Smart Radar Level Sensor 4-20mA for Slightly Corrosive Liquids Made in China
6.8GHz Radar Level Transmitter Product Description
The NYRD801 Radar level transmitter is a 6.8GHz high-frequency radar level measuring instrument with a maximum measurement distance of 20 meters. The transmitter transmits and receives very short microwave pulses with very low energy through the antenna system. Radar waves travel at the speed of light. Then the running time can be converted into a level signal through an electronic component. A special time extension method ensures stable and accurate measurements in a very short period of time.
Even if there is false echo under complex working conditions, the echo of material level can be accurately analyzed with the latest microprocessor technology and debugging software.
6.8GHz Radar Level Transmitter Working Principle
Input:
The antenna receives the reflected micro pulse and transmits it to the electronic circuit. The microprocessor processes the signal and identifies the echo generated by the micro pulse on the material surface. The correct echo signal recognition is completed by pulse software, and the accuracy can reach millimeter level. The distance D from the material surface is proportional to the pulse time travel T: D=C×T/2(C is the speed of light)
Since the distance E of the empty tank is known, the material level L is: L=E-D.
Output:
It is set by inputting empty tank height E (= zero point), full tank height F (= full scale) and some application parameters. The application parameters will automatically adapt the instrument to the measurement environment, corresponding to 4-20mA output.
