6.8GHz Anti-explosion 4-20mA Radar Level Sensor/Transmitter with 35m Range to Measure Solid Material and Grain Warehouse
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.
