PC-based and modular data-acquisition systems—cards and boxes—have been around almost as long as the PC itself (Ref. 1). But because these components were usually just part of a larger system, users ...

In the previous article, Data Acquisition and Instrumentation: The DAS and Sensors, we looked at the electronics and sensors involved in data acquisition systems (DASs). In this second part, we look ...

Failure to calibrate instrumentation can negatively affect performance, while calibrating too frequently can result in excessive costs without providing any benefits. The question is, how do you ...

THERE is no better way to ruin a perfectly good day than to make a mistake in the use of your air monitoring instrumentation. Industrial hygienists; military, industrial and public-sector hazmat teams ...

Statistical procedures give statistical answers not analytical judgement. Linear calibration is usually considered easy, particularly for high-performance liquid chromatography (HPLC) methods. After ...

The use of remote data loggers for assessing machine-specific maintenance needs can be integral to an optimized predictive maintenance strategy. Predictive maintenance (PdM) is one of the most ...

• Force vectors don’t want to remain in line with the object being pushed. • Load-cell specifications usually do not call out accuracy, but rather linearity, repeatability, and hysteresis. • Accuracy ...
