Guided Wave Radar Level Transmitters

The guided wave radar's self-monitoring capability continually checks for any faults that could cause device failures or false indications. The device features a graphic display incorporated into an all digital electronics module. Using this new format ABB has been able to add waveform screens to the modular electronics along with easy to follow multiple choice setup menus. These menus can be changed to many different languages for easy commissioning throughout the world. Pulses of microwave energy are directed to the product surface using a rigid rod or flexible cable type probe. This assembly has no moving parts and no loss of energy due to beam divergence.

Customer benefits:

• Microwaves are unaffected by temperature, pressure, specific gravity and vapors
• Easy to install
• No moving parts
• Ignores light continuous coatings
• Good for vacuum service
• No beam angle to be concerned about like through-air radar or ultrasonic transmitters
• More direct energy return – more consistent signal
• No complicated setup, no computer or programmer required
• Built-in waveform screen (Scope Trace)
