JC806 26G Non-contact Radar Level Transmitter

JC806 26G Non-contact Radar Level Transmitter 

JC806 26G Non-contact Radar Level Transmitter are a kind of measuring instrument based on the time travel , radar wave are travelling as light speed , the travel time can be transformed into level signal by the electronic parts . The detector can send the HF pulse and spread along cable , when the pulse meet the level surface , it will be reflected and received by the receptor inside the instruments , then the receptor will transform the distance signal into level signal.

 Input

The reflected impulse signal is transmitted along the proble to the circuit of the gauge . The microwave processor processes this signal , and recognizes the wave echo of the microwave impulse from the material surface . The correct wave echo signal is recognized by the intelligent softwave , the distance from the material surface D is proportional to the flying time of the impulse T:

D=C×T/2

C is the velocity of light .

As the distance of the empty tank E is known , so

L=E-D 

Output 

By inputting empty tank height E(zero point) ,full tank height F(full measuring range) and some application parameter are set . With the application parameters , the transmitter will automatically adapt itself to the measuring enviroment, corresponding 4-20mA output .
