LMS Pimento Data Collector - Multi-channel mobile data collector for noise and vibration analysis

LMS Pimento Data Collector - The Pimento compact, rugged design, portable multi-channel data acquisition system is the personalized tool for traveling professionals in diagnostics: capable of handling most tasks in data collection and processing, whether it's rotating machinery analysis, acoustic, or structural analysis. Additionally, it offers incredible mobility, feeling just as comfortable in the field as in the lab.

Its use is incredibly simple and fast: connection, power on, measurement, and evaluation can be done immediately, along with result documentation. The device design can be fully customized to the user's needs. The smallest-equipped Pimento instrument comes with 4 analog channels, but it can be expanded up to a 24-channel system.

• compact, rugged design, portable multi-channel data acquisition system
• AC, DC, or internal battery-powered
• 4 ... 24 - analog channels providing ICP power supply and signal conditioning
• 24-bit signal digitization, up to 1 MS/s data transfer to PC (or Laptop)
• 20 kHz bandwidth with multi-band and real-time octave analysis
• tachometer input for synchronized (tracking) analysis
• CAN bus support
• 24-bit DAC signal output for structural analysis
• quiet operation (no cooling fan)
• Windows-based operational and evaluation software package

LMS Pimento Data Collector - Measurement and digitization

The Pimento offers both real-time data acquisition/evaluation and post-analysis of continuously recorded data. The latter capability is primarily used for the analysis of experiments that can only be performed once, which need to be recorded for various detailed analyses. A real-time oscilloscope is available for displaying signals in the time and frequency domain simultaneously. Channel sampling and bandwidth can be individually adjusted to eliminate unnecessary data volume.

• parallel signal digitization on each channel for real-time measurements
• high-speed data transfer to PC hard drive via Firewire interface
• up to 51.2 kHz sampling, 20 kHz bandwidth, and multi-band analysis per channel
• comprehensive real-time data display and evaluation
• post-octave, harmonic, spectrum, and time-domain analysis

Rotating Machinery Analysis

The Pimento is capable of rotation-synchronized measurements, enabling spectrum, octave waterfall, color spectrum, and harmonic analysis of rotating machinery. Through rotation signal conditioning and digital processing, precise results can be achieved under industrial conditions even when the shaft speed fluctuates significantly.

• rotation signal conditioning with tracking multiple pulses per revolution
• clear rotation frequency indication
• waterfall spectrum and color spectrum (user-definable colors)
• rotation-synchronized analysis and data collection
• easy data comparison for measurements at different speeds

Structural Testing (Structural Analysis)

The Pimento with up to 24 - ICP- and TEDS sensor-supporting - analog channels contains everything needed for structural testing. Excite the structure with impact (hammer) or use a shaker with various excitations - the Pimento offers real-time display of response spectra, transient response, coherence, and impulse response.

• intelligent sensors (TEDS) support (per channel, built-in)
• ICP sensor power supply and control (per channel, built-in)
• 24-bit DAC analog output and 24 analog inputs in a single instrument
• impulse and excitation (shaker) tests
• compatibility with LMS modal analysis software

Acoustics (Noise and Sound Analysis)

The Pimento is an ideal tool for sound and noise analysis, whether in the laboratory or in the field. As it has no cooling fan, it can receive and analyze signals from a 6x4 microphone array quietly, following the ANSI standard.

• powering and monitoring up to 24 ICP microphones
• octave and third-octave analysis according to ANSI standard
• acoustic weighting for broadband values
• sound pressure level calculation

Efficiency-enhancing capabilities

Numerous features facilitate measurement and evaluation. It is possible to create virtual signals (signals calculated from analog signals through mathematical operations); automation of measurements, evaluations, and documentation processes is also possible. Meanwhile, the Pimento can organize, label, and link data. All data and graphs can be directly printed, transferred to Windows programs (e.g., MS Word) using drag-and-drop, or exported. The data is compatible with the LMS CADA-X and LMS Virtual.Lab software packages. Through the LMS Tec.Manager software, measurement results can also be used for engineering teamwork.
