Road Load Data Instruments
DEWE-RLD ... One system for in-vehicle and test rig

t Up to 204.8 kS/s per channel
sample rates (binary sampling rates
such as 409.6 Hz possible)
t Universal inputs (voltage, acceleration,
strain, etc.)
t Synchronized acquisition of data from
Kistler RoaDyn ® measurement wheels
t Up to 8 CAN bus interfaces
t Export to different file formats
(supports RPC III)

t Realtime analog output for test rig application
All DEWETRON Road Load Data instruments offer high quality
analog inputs with 22 bit resolution and anti-aliasing filters.
t Realtime mathematics
Practical functions include sensor balance and shunt sensor
calibration for the bridge/strain gauge inputs. The system can
fast-check all inputs or inputs groups for errors. During the data acquisition, the overload display gives an overview
of all recorded signals. As various sensors are used, the analog inputs are universal inputs, natively supporting
voltage, current and bridge type (full, half and quarter) sensors. Via optional MSI (Modular Smart Interfaces) ICP®
sensors, thermocouples, Pt100 to Pt1000 and charge measurements can be done as well. A powerful sensor database and TEDS support are integrated into the software. Besides the analog data also CAN bus and digital status
information or counters have to be acquired. DEWETRON RLD systems guarantee the synchronous measurement of
all these different types of signals, including video and GPS acquisition of data.
The thorough synchronization of all these signals results in a high-quality data. However, other important considerations are the size of the equipment, or the ease of use. DEWETRON is a clear winner in these categories.
For testbed simulation the acquired data is exported to RPC III file format and then replayed on the test rig. As an
option, some DEWETRON RLD instruments even can be equipped with a real time analog output and used on the
test rig, too.

Components

There is a nice choice of standard models which can be
ordered as a single item. The most compact system DEWE211-RLD is 32 x 25 x 9 cm (12.4” x 9.9” x 3.6”) in size, about
5 kg (11 lbs) light and offers 16 universal analog inputs, two
counters, 16 digital inputs and 2 CAN bus interfaces, as well
as support for Kistler RoaDyn ® 2000 wheels over Ethernet.
Further standard instruments with 64 up to 128 analog inputs
and 4 to 8 CAN interfaces are available.

Key Features

Software

The DEWETRON RLD series offers many possibilities for
testing the reliability of various vehicle components. The systems are compatible with most sensors (e.g. synchronized
to Kistler RoaDyn ® 2000 measurement wheels) while having
a very efficient offline set-up. High-quality data acquisition is
guaranteed in the shortest amount of time possible.
