Features
Available with 8 and 16 measuring slots
Integrated touch panel display
Measuring cards can be configured and exchanged by the user
Expandable number of channels by cascading multiple RASdelta front ends
Data logger optionand remote control available (no PC connection required for data acquisition)
The RASdelta measurement system is a modular, flexible and high-precision data acquisition system (DAQ). The device is available as an 8-slot and 16-slot version and can be configured for individual measurement tasks on the test bench and for dynamic measurements in the vehicle.
In addition to its compact design, the system offers a touch control panel that can also be used to configure the RASdelta as a data logger. Cascading of up to 6 RASdelta systems is easily possible via the second Ethernet interface.
The measuring system is configured by the user for the individual application. The required measuring cards are selected from the catalogue below.
Trigger card
Synchronises all measuring cards, channels and cascaded systems
1x TTL trigger input with adjustable threshold values
2x TTL output for online monitoring
Power supply for electronic units (DC 5 V and 12 V; 5 W)
The RASdelta trigger card synchronises all measurement data between the channels, acquisition modules and connected front ends. As a master card, it is an integral part of the RASdelta.
Speed card
2-channel measuring card with 12 GHz counter clock (time resolution = 0.081 nanoseconds)
Signal inputs for direction and reference pulse detection
Adjustable values for trigger threshold and edge
Operating modes: speed, frequency, duty cycle, on/off ratio
The RASdelta Speed Board records precise multi-channel and digital speed measurement data for all transmission, control and auxiliary drive tests. It is therefore the basis for torsional vibration analysis. The data is recorded via magnetic, angle-equidistant scanning, an incremental encoder or a laser.
RASdeltaANA8
8-channel measurement board
2x 4 channels galvanically isolated
AC- and DC- coupling, power supply for IEPE (ICP) sensors
Adjustable voltage ranges for input signals
24 bit SigmaDelta ADC
50 kHz max. sampling rate per channel
24 kHz analogue bandwidth
The RASdelta analogue board (8-channel) measures analogue variables such as airborne and structure-borne sound, acceleration, temperature, displacement or pressure. These variables can be used to determine the position of a sound source or to analyse the valve train or cylinder pressure. The analogue measurement data is recorded by time-equidistant sampling.
Analogue cards

24 kHz analogue bandwidth
DMS card
2-channel measuring card
Max. Sampling rate: 50 kHz per channel
Supports full bridge and half bridge applications
Adjustable bridge supply voltage: 1 V, 2.5 V, 5 V, 10 V
Supports four-wire and six-wire configuration
Automatic zero balancing
Detection of line interruptions/burn-out
The RASdelta strain gauge card is an integrated two-channel DC voltage amplifier for signal acquisition from strain gauge-based, piezoresistive, magnetoresistive or potentiometric transducers. These include force, torque, pressure, displacement and angle sensors or scales. The card does not require any additional measuring amplifiers.
CAN-BUS card
2-channel measuring card
Max. Baud rate: 1 Mbit/s per channel
Adjustable post-sampling rate
CAN standard 2.0 A (11-bit identifier) and 2.0 B (29-bit identifier); OBDII; J1939; (CAN-FD via PC USB connection)
Modes: active/passive listener
Adjustable BUS termination (120 Ohm)
The CAN-BUS card records CAN and OBD-II variables and analyses them in relation to the torsional vibration analysis. This means that existing variables can be included in the measurement without the need for additional sensor applications. In addition to OBD II, Raw CAN and SAE J1939 protocol, it is possible to record FD CAN data directly via the measurement PC and separate third-party hardware.
Temperature card
8-channel measuring card
Maximum sampling rate: 1.6 kHz per channel (when using 4 channels)
Temperature measuring range: -200°C - 850°C
Supported sensors:
- Pt100/1000
- Type J thermocouple (Fe/CuNi)
- Type K thermocouple (NiCr/Ni)
- Type T thermocouple (Cu/CuNi)
With the RASdelta temperature measurement card, you can record measurement data from resistance thermometers and thermocouples.
Measuring the oil temperature in vehicles is essential, especially when analysing transmissions.
