DBI (HART) INSTRUCTION MANUAL

The dBi Series Intelligent Transducer operates on the principle of timing the
echo received from a measured pulse of sound transmitted in air and utilises
“state of the art” echo extraction technology.
dBi Series Intelligent Transducer comes in four models:
1. dBi 3 with a range from 0.125m (0.41 feet) to 3.00m (9.84 feet).
2. dBi 6 with a range of 0.3m (0.98 feet) to 6.00m (19.69 feet).
3. dBi 10 with a range of 0.3m (0.98 feet) to 10.00m (32.81 feet).
4. dBi 15 with a range of 0.5m (1.64 feet) to 15.00m (49.213 feet).
All models can be mounted via a rear, 1” BSP/NPT, thread (Standard) with a
model with alternative front thread mounting being available, in addition to
this flange mount and PVDF options are also available. See
Chapter 2
Installation for further details.
All model types are available for use in hazardous area installations with
either Ex mb or Ex ia ATEX certification.
The dBi Series Intelligent Transducer has a 4 to 20mA output which can be
programmed to give an output proportional to
level , space, distance or
volume, dependant on the measurement mode selected and provides a
‘fault condition’ alarm of either 3.8mA or 22mA.
Boot time for the dBi Series intelligent Transducer from power up to stable
reading: cold boot = 9 seconds, warm boot = 4 seconds (if within 12hrs from
last start up). For 4 to 20ma set proportional to measured level/distance.
