Description
The mmWAVE Radar (dBR16 and dBR8) are new FMCW non-contacting radar level
measuring sensors designed to meet the requirements of today’s demanding process
level measurement applications for liquids and solids.
The mmWAVE Radar features an innovative design, which has no extra antenna
requirements, that can offer very high performance and effective radar level sensing. It
gives all the advantages associated with radar technology and offers best-in-class
performance with a narrow beam angle and a range from 0.077 to 8 metres for a dBR8,
and 16 metres for a dBR16. The signal emanates from the curved face of the radar, but
for the purposes of measurement it is measured from the drip shield.
Housed within a robustly engineered enclosure, the mmWAVE Radar is designed for
easy retrofitting to any of Pulsar’s many controllers (including the Ultimate, Ultra series
and BlackBox) all as a microwave alternative to a dB transducer. Using the latest
versions of firmware: Ultra 7.5.1, Ultra Twin 1.5.1, BlackBox 2.1.1 and Ultimate 2.1.10
and onwards the mmWAVE radars can be programmed for use in P101 (transducer).
For further information on setting up Radar with a controller please consult Pulsar for
assistance.
Two ATEX / IECEx approved versions are available:
1. Ex ia (IS): for zones 0,1 and 2
3-wire, for use with Pulsar’s standard range
of controllers. Tamb. -20°C to +80°C
2. Ex mb: for zones 1 and 2
3-wire, for use with Pulsar’s standard range
of controllers. Tamb. -20°C to +80°C
Standard cable lengths:10, 20 or 30m. A range of mounting brackets are available.
Not all mmWAVE sensors are certified for use in hazardous areas; check the label for
approval details. Labels for the two versions of protection are show below:

Key Advantages of mmWAVE Radar
•World beating long range non-contact radar level sensor.
•Class-leading performance, range and exceptionally narrow beam angle.
•Excellent accuracy and repeatability.
•State of the art, proven, algorithms for ignoring unwanted targets (DATEM).
•Measure contents through non-conductive container walls.
•Unaffected by fog, haze, mist or rain.
•Independent of ambient temperature.
•Immune to inert gas, vapour, steam or pressure.
•Direct retrofit to Pulsar controllers.
•No extra antenna selections required no matter what the application.

The mmWave Radar should be installed directly above the material to be measured, at a
90° angle. Avoid positioning near the process filling or emptying areas. Check there are
no obstructions between the sensor and the material. The mmWAVE Radars can be
installed via the 1” BSP/NPT thread on the sensor, or with the supplied 1” BSP to M20
adapter. Installing the mmWAVE Radar outside of a closed vessel, the following must
be adhered to:
•The mmWave Radar must be directed vertically downwards.
•Special permission must be granted by the appropriate national authority, to mount
the mmWAVE Radar closer than 4km from any radio astronomy stations.
•The mmWAVE Radar must not be installed higher than 15m from the ground when
installed within 4-40km of a radio astronomy station.
