How to Connect the ABB LWT Series Guided Wave Radar Level Transmitter Remote Head


The ABB LWT Series Guided Wave Radar Level Transmitter uses radar frequencies, guided in a probe going into the tank or vessel, to provide continuous, reliable level measurement with high accuracy. LWT300 series instruments cover a wide range of applications. They can meet your needs for applications up to 204 °C (400 °F) and 207 bars (3000 psi). ABB LevelExpert technology concentrates over 20 years of industrial level measurement experience into an intelligent instrument made to accurately detect levels, even in the most demanding conditions.


Certain process conditions warrant the use of a remote head on the LWT300 instrument. Remote head instruments are also very useful for any reason where you might prefer or need to distance the head from the coupler (ease of access, floating roofs, etc.)

There are three main steps to installing a remote head instrument:
  1. Installing the probe-coupler assembly in the vessel. See LWT Series Guided Wave Radar Level Transmitter user guide for instructions.
  2. Installing the head on a support bracket in a remote location. See LWT Series Guided Wave Radar Level Transmitter user guide for instructions.
  3. Connecting the probe-coupler assembly to the instrument head with the proper coaxial communication cable.
This video demonstrates step three, the actual cable and remote head connections.

Procedure:
  • When connecting either end of the coaxial cable, we strongly suggest the use of a wrench or pliers.
  • Connect one end of the coaxial cable to the bottom of the head-coupler adapter.
  • The coaxial cable bend radius shall not be less than 150 mm (6 in).
  • Connect the other end of the coaxial cable to the top of the coupler.
  • Complete.
