The Fact, Folly and Mathematics of Analog to Digital Converter Resolution

Data Acquisition > Software > WinDaq Everyone agrees that higher resolution analog to digital converters (ADCs) are better, right? So why do so many end-users shell out bucks for one and then fail to exploit that advantage? What I mean is that we are too often shocked when we receive data files from customers with Read More

Data Acquisition Gain and Dynamic Range Considerations

Data Acquisition > Software > WinDaq Attempting to acquire a millivolt level signal with too low a gain factor is like trying to read a license plate from a hundred yards away. In order to read the plate you would need some sort of magnification, a pair of binoculars perhaps. In the realm of data Read More

How Much ADC Resolution Do You Really Need?

Data Acquisition or Data Logger You just bought a data logger or data acquisition system with a 14-bit ADC (analog-to-digital converter.) What exactly does that mean? Could you have gotten away with a 12-bit product? A 10-bit? Did you gaffe and really need a 16-bit data logger? You know that a higher “bit” number is Read More

4-20 mA Current Loop Measurement Resolution Calculations Made Easy

Data Acquisition > Current I estimate that 20-30 percent of measurements made by our customers are from 4-20 mA current loop sensors and systems. If you draw a blank after reading this first sentence, see this and this for some 4-20 mA background information. One question that arises quite often is how to calculate measurement Read More
