We provide Contact Type Radar Level Transmitter. The 3300C Guided wave Radar is a transmitter based on “time and domain” principle. The radar waves run along a probe at speed of light, the running time can be converted to a level signal through electronics. The sensor emits
high frequency impulse and transmits along the probe. When the impulse meets the material surface, it reflects back and is received by the receiver inside the transmitter, which converts the distance signals to the level signals.

The reflected impulse signal is transnmitted along the probe to the electronics of the transmitter. 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 software. The distance from the material surface ‘D’ is proportional to the flying time of the impulse. . where C is the velocity of light. As the distance of the empty tank E is known, so L=E(-)D.
