Radar Gauge

Components of the
APEX and
APEX Sentry Radar
Gauges

The top of the APEX and APEX Sentry Radar Gauges is an aluminum

gauge

housing

(see Figure 1-1)

.

The gauge housing includes advanced radar

electronics for signal processing.

The

radar electronics

is the heart of the gauge. It produces an

electromagnetic wave by using an oscillator that converts direct current (dc)
power into a radar signal. It also receives the return signal.

The radar signal passes from the electronics through a

waveguide

containing

an alumina ceramic process barrier. The waveguide is the entire path from
the electronics to the antenna.

The

antenna

is a cone-shaped device made of stainless steel. The antenna

controls the signal beamwidth by helping to keep the radar signal focused on
its target (the product in the tank) so it does not spread out over the entire
vessel and give false echoes. A larger antenna provides a more focused,
narrow beam. (Refer to Appendix A: Reference Data for further information
regarding beamwidth.)
