More Information:
TDR Guided Wave Series
Principle of Operation
The contact cable / probe emits a high powered Radar Wave transmit pulse
which is reflected from the surface of the material being measured. The
reflected signal is processed using specially developed software to
enhance the correct signal and reject false or spurious echoes.
The transmission of high powered Radar Wave with minimal losses through
the environment where the sensor is located. Due to the high powered
emitted pulse, any losses have far less effect than would be experienced
by traditional TDR devices. More energy is transmitted hence more energy
is returned. Advanced receiver circuitry is designed to identify and
monitor low level return signals even when noise levels are high. The
measured signal is temperature compensated to provide maximum accuracy to
the outputs and display.
