Guided wave radar transmitter works on the principle of time and travel (TDR). Radar wave travels at the velocity of light. The flying time is converted into level signal via the electronic units. The probe emits high frequency wave pulses which travel along a cable probe or a rod probe. When the wave pulses reach surface of a medium, it will be reflected back and received by the receiver, and then the distance signal will be converted into level signals.
Guided Wave Radar Level Transmitter
- Liquids or solid powders
- Solid powders and low dielectric constant liquids.
- Corrosive liquids
- Liquids with lower dielectric constant or liquids with wavy surface, best choice for measurement of storage tank with complicated inner structure
- Cable probe, two optional sensor types: for liquids or solids.
- Single rod probe
- Twin-cable probes
- Sensor for high temperature and high pressure. Single rod probe and coaxial probe are available for option
- PTFE Single rod probe
- Coaxial probe
