Dynamic Measurement & Vibration Control
The Spider-80X is designed for applications in three fields: dynamic data acquisition, vibration test control, and machine monitoring. Each front-end features eight analogue input channels and two channels that may be software-selected as analogue outputs for vibration control or tachometer inputs for the analysis of rotating machinery.
Each front-end features eight analogue input channels and two channels that may be software-selected as analogue outputs for vibration control or tachometer inputs for the analysis of rotating machinery.
A single Spider-80X front-end is a complete two-output controller with the same high-quality patented dual ADC input technology of the Spider-81 series. The Spider-80X inputs provide single-end/differential and AC/DC/IEPE coupling choices; charge mode is an available option that can be installed at the factory. The Spider-80X also provides the same time sync Ethernet connectivity and has 4 GB flash memory for data and program storage.
High Precision Front-end Design
The Spider-80X analogue input channels offer high precision measurements with single-ended or differential AC/DC input coupling. They support IEPE input mode for industry-standard accelerometers, reading TEDS identification for IEEE 1451.4 compliance. Each channel features a dynamic range of 175 dBFS, achieved by utilising two 24-bit analogue-to-digital converters and combining their outputs, as detailed in US Patent 7,302,354.
Time Accuracy and Synchronisation
The Spider-80X supports IEEE 1588 PTPv2 and can integrate with a grandmaster clock for sub-microsecond time-stamping accuracy. This enables synchronisation of multiple disconnected units within 100 nanoseconds. The Spiders maintain a phase match of less than 1 degree, allowing for precise computation of frequency response functions, cross-spectra, autocorrelation, and other signal analyses.
Black Box Mode
Black Box mode enables Spider-80X operation without a PC. In this mode, a PC is used only to configure the control system before the system starts operation and to download data after the test is completed. During the test, the data acquisition system operates autonomously, according to a preset schedule or in response to external events such as an input trigger or a digital input. If your PC crashes for any reason, the test profile will continue to run uninterrupted.
Simple Network Connection
Ethernet connectivity allows Spiders to be located far from their host PC. This distributed structure greatly reduces noise and electrical interference in the system.
