Centurion Guided Radar Level Transmitter

Centurion Guided Radar Level Transmitter

The Centurion Guided Radar (CGR) Level Transmitter is ideal for the measurement of liquids, sludge, powders and granules to a range of 38m (124ft) for level and interface. This technology is not affected by pressure, temperature, viscosity, vacuum, foam, dust, changes in dielectric constant or coating of the probe.

Principle of Operation

Microwave pulses are transmitted along a cable or probe to the product being measured. At the point where the wave meets the product surface it is reflected by the product. The unit automatically calculates the distance to the pulse reflection using time of flight & time expansion. The intensity of the reflection depends on the dielectric constant of the product. The instrument measures the time between emission and reception of the signal which is proportional to the distance.
