Radar Level transmitters

• Set Up, Working Principle, Types Industrial
  Applications

2
Introduction

• Radar Level Transmitters are used is different
  applications for fluid measurement. The function
  of these transmitters are based electromagnetic
  waves at a range of 10GHz.
• There are two types of Radar Level Transmitters
• Non-Contact Systems
• Contact Systems

3
How to Setup Radar Level Transmitter?

• Setting up the Radar Level Transmitters is rather
  easy. There are three main components that are
  required for setting up these Transmitters
• Solid-State Oscillator
• A Radar Antenna
• Receiver and Signal Processor System
• Along with these components, TTS offers Setup
  Wizard with advanced systems. It acts as a
  software interface to the transmitter operation.

Working Principle of Radar level transmitters

• The working principle is a function of Time
  Domain Reflectometry (TDR), which is also known
  as the Time of Flight (TOF) radar measuring
  principle.
• Following is the step-by-step explanation of
  Radar Level Detectors working principle
• Firstly, the solid-state oscillator is installed
  in radar level sensor setup oscillates
  electromagnetic waves to the fluid surface.
• After the electromagnetic waves hit the fluid
  surface, it reflects a pulsating signal to the
  radar antenna.
• The time to level calculation is performed by the
  signal processor.

Different Types of Technologies In Radar Level
Transmitters

• Guided Wave Radar Level Transmitters It is a
  contact type of transmitter, where TDR probes are
  immersed in dry or bulk media. TDR Probes can
• Detect the advancing motion of the
  electromagnetic waves
• It get rids of obstacles in between the path of
  waves.
• These probes are highly immune to high
  temperature, pressure and environmental damage.
• This technology is suitable for harsh environment
  and is highly compatible with high-end industrial
  applications as it require zero maintenance. TDR
  technology is used in the guided wave radar level
  sensors and guided wave radar level transmitters.

Different Types of Technologies In Radar Level
Transmitters

• Frequency Modulated Continuous Wave (FMCW)
  Transmitters Radar Antennas are used in
  transmitters which are working on FMCW
  technology.
• The radar antenna emits a signal and the receiver
  catches it within a specific time. 
• Transmitters with FMCW Technology are non-contact
  systems.
• This technology emits high-frequency continuous
  signals with gradually increasing frequency.
• Due to frequency sweep, continuous measurement is
  possible in this technology.

Applications of Radar Level Transmitters

• Radar Level Transmitters are used in critical
  engineering environments. The industrial
  applications are as follows
• Mining Industry
• Boiler Engineering
• Aeronautics Industry
• Paper and Pulp Industry
• Bore Digging Technology

Conclusion

• Now that we have understood the set up, working
  principle, types and applications of Radar Level
  Transmitters, it becomes important to make the
  correct choice by sourcing these devices from
  reliable supplier.
• TTS offers level measurement sensors from leading
  manufacturers like Emerson, Foxboro, Honeywell
  and many others.
