The DNx-AO-358 simulated strain gauge output boards from United Electronic Industries (Walpole, MA) have joined Adept Scientific’s (Letchworth, Herts) data acquisition product range.
The boards are available in two models — the DNA version, for use with UEI’s popular PowerDNA Cubes, and the DNR version, for rack-mounting in a PowerDNR RACKtangle or HalfRACK chassis. Both versions provide eight channels of simulated strain gauge output based on signals from real variable resistor bridges that accurately duplicate the behaviour of the strain gauges simulated.
Each version may be ordered in a full or half/quarter bridge configuration with 120, 350 or 1000 ohm bridge completion resistances. These new boards support both DC and AC excitation (DC to25 kHz range) with a system bandwidth of 250 kHz, minimum. The output update rate is 0 to 5 kHz. As an added feature each board also includes an on-board A/D converter that monitors excitation voltage to an accuracy of ±10 mV.
The boards are ideal for simulator applications in which an on-board device expects a strain gauge signal as an input. They are also useful for testing and diagnosing errors in a wide range of strain gauge systems.
The DNx-AO-358 boards include software drivers compatible with all popular operating systems such as Windows, Linux, QNX, VXWorks, RTX and other popular real-time operating systems. Windows users may also take advantage of the powerful UEIDAQ Framework, which provides a simple-to-use software interface to all popular Windows programming languages as well as DAQ and control applications such as LabVIEW, DASYLab and MATLAB.
According to UEI President Shaun Miller, “With the new DNx-AO-358 our customers can now design, build and test systems that require a dynamic strain gauge input without having to build a complex physical input device. For example, we are using the 358 ourselves at UEI for production testing of our strain gauge analogue input boards.”
