Industrial cable type radar level transmitter of stainless steel 316L
Quick Detail:
Description:
VT77 series Guided wave radar is measuring instrument based on the principle of time travel, the radar waves travel at the speed of light, the running time can be through the electronic components are converted into level signals. Probe a high frequency pulse and along the cable or rod probe propagation, when pulse meets the material surface is reflected back by the receiver instrument within the receiving and the distance signal into a 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 (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 .
Measuring Distance
The following table indicates the relations between mediums and measuring distance

Used for grain bin,oil/ fuel/water/powder tank, liquid
