Spider-80SG Data Acquisition with Strain Gage 8 Strain Gage Inputs Output Channel Power Power Input Reset Button Ethernet Data Port Master/Slave Switch Compact Testing Solutions The Spider-80SG/SGi is an eight-channel strain sensor processing system module useful for a wide range of physical tests and measurements. Spider-80SG/SGi is a natural adjunct to Spider-80X systems for machinery monitoring and modal analysis applications. This is a flexible module appropriate for low frequency “static” stress/strain measurements and bearing temperature monitoring as well as rapid dynamic stress...

Spider-80SG Features Overview 8 strain gage / general purpose inputs per front-end 24-bit ADC channel Supports multiple measurement quantities Supports a variety of strain gages, load cells, pressure transducers, torque sensors, accelerometers and geophones User selectable excitation voltage User configurable synchronized sampling rate Remote sensing Precision excitation voltage of ±2.5V and ±5V Power supply voltage of 2.5V, 5V & 10V for sensor excitation Shunt calibration Offset nulling for any measurement quantity Multiple trigger modes Compact, portable design Scale up to 512 channels...

Dual Modes of Excitation The Spider-80SG is equipped with dual excitation modes. There is an option for Precision Excitation Voltage of ± 2.5V or ± 5V that can be used to excite a strain gage or a strain gage based sensor and measure the minute change in resistance accurately. Remote Sensing The Spider-80SG has been tested to work on strain gages up to 1000 ft away from the analyzer using the remote sensing feature. Using an 18AWG 5 conductor cable to measure the excitation voltage using remote sensing and changes in output voltage, the error was measured to be less than 1.5% for up to...

Real Time FFT Analysis Comprehensive Data Acquisition with the Spider System The FFT Spectral Analysis provides comprehensive data acquisition and FFT analysis functions. Acquisition Mode controls how the data is acquired block-by-block and processed with the signal analyzer functions. These time blocks can be either gap-free, overlapped, or with gaps, depending on the acquisition mode selection. Sampling Rate can be set from control panel directly. 54 sampling rate stages available and can be changed without stopping data acquisition. 3D waterfall processing allows the data acquired and...

Variable Sampling Rate in the FFT Analysis provides a convenient way to select sampling frequencies of each module in a high channel count system. Measurement quantities such as strain, temperature or pressure often require a much lower sampling rate when compared to acceleration or sound pressure. The variable sampling rate could be efficiently used to select a user defined sampling rate for each front-end while acquiring synchronized data from all channels in the system. 3D signal waterfall displays are available for block signals in all types of tests. 3D signals can be plotted with...

Automated Production Testing Solutions Automated Production Testing Solutions Automated production testing is critical in today’s competitive manufacturing environment. Companies can no longer rely on variable costs, non-uniformity, and potential health hazards that come with a laborer-based manufacturing line. This is no less true for sound and vibration tests , ranging from in-process burn- in tests to product validation and verification tests. The measure- ment tools and intelligence behind present day manufacturing include data acquisition equipment as well as closed-loop control. And...

Step 1: EDM sets the alarm limit together with a special message string, such as “Exceeding Limit”. Black Box mode provides the ability to run Spiders without an attached computer. The Spider API, when used along with Black Box mode, is the gateway to integration with LabView, Mat-lab and other scripting software. A cellular phone, tablet or PC can control multiple Spider front-ends at distributed locations running disparate tests from a single control screen. Limit Configuration Alarm limits could be defined independently and multiple limits could be defined to each channel and may be...

Native Channels Time Streams Data Conditioning CSA-based time stream processing Data Conditioning and Recording Phase Signal Analysis Phase (FFT, Transient Capture, Octave Analysis, Run-up Run-Down Testing, Balancing) In a time-critical test, it is highly desirable to record the raw time data continuously, so that the data can be analyzed later when more time is available for a complete review. Integral raw data recording eliminates the need for a separate recording device so necessary just a few years ago. The Spider platform simultaneously performs both real-time processing and continuous...
