Precision's Industry-leading Analog Signal Conditioning Now Available in a Complete Data Acquisition System
The Precision SDAS is a compact 16-channel DAQ system that integrates Precision Filters' trusted signal conditioning with cutting-edge 24-bit A/D converter technology. It comes in configurations to accommodate dynamic strain, charge, IEPE, and bridge-type sensors, covering a wide range of measurements. The 24-bit digitizers support synchronized sampling rates of up to 312.5 kilosamples per second per channel, allowing for 135 kHz analog signal bandwidth measurements. Digital filtering modes support optimized frequency response for time or frequency domain analysis. Buffered analog outputs are provided for driving backup A/Ds or control and safety systems. Digital calibration ensures unparalleled accuracy from the sensor interface through A/D conversion. Multiple SDAS16 units can be distributed around a test article, with precise time-stamping and synchronization via the IEEE-1588 PTP protocol or IRIG-B. Data is streamed over a 1 GB Ethernet to the host for analysis and storage.
The SDAS includes an intuitive software package for system setup and recording, designed for ease of use by the operator. Basic time and frequency domain analysis is provided on a multi-scope display. Multiple TCP/IP connections can be made to third-party software packages such as Dewesoft, Labview, and others to enable extensive real-time display and analysis while data is being recorded.
The SDAS system features built-in go/no-go verification tests that ensure correct system setup via direct measurements. The SDAS also includes automated NIST traceable annual calibration routines for verifying system specifications. The system form factor is a compact 19” x 10.5” x 1.75” rack-mountable package with extended operation from 0 to 60 ºC.
