The
blackbox
ultrasonic Level System sends a transmit pulse to the
transducer, which emits an ultrasonic pulse perpendicular to the transducer
face, and the returned echo is sent back to the
blackbox
. The time taken to
receive the echo is measured and the distance from the transducer face to the
surface being monitored is calculated.
The
blackbox
utilises the unique DATEM software (Digital Adaptive
Tracking of Echo Movement). This is an entirely new digital mapping
technique developed especially for the Pulsar’s range of ultrasonic level and
control systems. It gives the system edge when identifying the “true target
level” in the face of competing echoes from pipes, pumps or other
obstructions.
The
blackbox
can measure from zero to 40m from the transducer to the
surface being monitored, dependent on the transducer used.
The
blackbox
can measure
level
,
space or
distance
and provide a
representative output. There are two user definable relays, with individual
setpoints, which can be programmed to activate alarms or control functions,
a voltage output that can be used for remote indication purposes and a
RS232 port, so that the
blackbox
can be programmed or monitored remotely
by a PC or other equipment.
The
blackbox
can be programmed either by PC, via the RS 232 Serial
Interface, using the supplied software (standard) or by hand held calibrator
(optional) which is connected to the
blackbox
via the RS 232 interface.
All the parameters are stored in non-volatile memory, so are retained in the
event of power interruption.
