LMS SCADAS III

Signal Conditioning and Data Acquisition for Lab and Field Testing -

LMS SCADAS III offers complete, high-quality and cost-effective solutions for high-speed data acquisition and signal conditioning, in a wide range of applications. The SCADAS III front-end is tightly integrated with the LMS Test.Lab software and optimally tuned to meet the specific needs of noise and vibration engineering. It offers a flexible choice of hardware frames and modules and an outstanding performance.

Maximum modularity…

The modular LMS SCADAS III solution can expand from an inexpensive base with only four channels, to a mobile solution for operation from a vehicle battery, to a distributed system with over a thousand channels. SCADAS III has a very flexible architecture that lets you configure the system to your precise needs – add more channels, swap signal conditioning modules and boost the signal processing power as you wish. The LMS SCADAS III front-end family offers system configurations for laboratory and mobile usage, and offers the possibility to standardize laboratory and field-testing on the same hardware platform. The tight integration of LMS SCADAS III with the LMS Test.Lab software offers operators the comfort of working with the same common software platform for all their testing tasks, both in the lab and in the field.

…and optimal scalability

The scalability of LMS SCADAS III enables its users to apply a high number of measurement channels in extensive testing campaigns, using a daisy-chained master/slave configuration, or divide the channels over multiple separate testing systems. The master frame can optionally be connected to the host computer by a fiber optic link with a maximum length of 500m, and each slave frame can be over 50m away from the previous master or slave frame. This distributed approach means that you can minimize costly transducer cabling - and obtain much higher quality measurements.

Higher quality data, with measurement chain integrity indication
Parallel signal processing capacity safeguards system performance as channel count increases

High performance digitization and DSP

The outputs from the various signal conditioning modules are routed to the SP92 digitizer cards in a very flexible and software controlled manner. Digitization incorporates state of the art delta-sigma techniques that combine an ultralow noise floor with fully linear 24-bit system performance

at up to 204.8kHz per channel. The combination of a high throughput capacity host interface with 24-bit fixed point DSPs on each four-channel module enables a maximum distribution of processing power for true real-time operations on a large number of channels. Processing functions include digital filtering and decimation, order tracking and harmonic extraction, as well as real-time third octave filtering.

Designed for noise and vibration engineering

LMS SCADAS III supports virtually all types of transducers relevant in the world of NVH measurements. Whether you want to capture rpm, acceleration, speed, force, displacement, strain, temperature, sound or torsion: SCADAS III offers an off-the-shelf solution. Dedicated high precision tacho acquisition allows order tracking as well as spectral/ octave acquisitions against rotational speed. Tacho signals up to 15kHz and 1024 pulses per revolution are supported, while auto-ranging inputs and programmable signal conditioning

ensure that even ‘industry quality’ analog tacho signals with all kinds of noise and changing amplitudes will still result into stable readings. For Vibration Control or Time Wave Replication applications, we offer the possibility of installing from 2 up to 60 generator channels in one single SCADAS III frame. Output signals with ultra-low distortion and noise are ensured by the use of 24-bit digital to analog bit stream converters.

Delivering superior hardware quality

LMS SCADAS III achieves high-level reliability through rigorous design standards, efficient quality control and a strong service organization. Our quality standards are the outcome of a 25-year accumulation of practical knowledge in signal conditioning and processing. We are critical when selecting components and suppliers - and quality control begins in the prototype phase. Our products are considered out of development only when the fi rst production series is completed successfully to ISO9001 standards. Careful tracking of each system module allows our service organization to carry out preventive maintenance for our customers so that downtime for calibration or repair is reduced to an absolute minimum
