Article: DASYLab drives forward

A typical data acquisition task will involve a mixture of input signals: temperature, force, displacement, pressure, flow, strain, acceleration, voltage, power, torque are typical examples. A new capability within the DASYLab data acquisition program for Windows makes such applications a lot more efficient.

DASYLab already supports a wide range of hardware, so you can, for example, use a standard board with thermocouple support for the temperature channels and a high speed board to capture more rapidly changing signals from, say, a displacement or pressure transducer.

However, if you need to sample the displacement at a high rate to get an accurate picture of what is happening in a mechanism, you don't want to be forced to sample the temperatures at the same rate ...particularly if they're just keeping an eye on motor temperature to make sure it's not going outside certain limits. A new multi-speed analogue input module, just added to the DASYLab driver for Adlink and Measurement Computing hardware, allows the sample rate on specified inputs which can be sampled more slowly to be set completely independently of the high speed acquisition taking place at the same time. This is a great way to capture just the data you need without creating disk files that are to big to analyse easily.

The current release of DASYLab supports a wider range of data acquisition hardware than ever before.
