Stand-alone Data Acquisition and Flash Memory

Stand-alone Data Acquisition and Flash Memory

For years, DATAQ has offered a number of different flash memory solutions for stand-alone data acquisition. Beginning with standard 2GB max capacity SD-style cards for older DI-710/718 series data loggers, progressing to the 32 GB thumb-style USB drives, included with contemporary DI-2000 and DI-4000 series instruments. With maximum sample rates on the order of 14.4 Read MoreSource: DATAQ…

Measuring Wind Speed Using an Anemometer with a 4-20mA Output and a DI-2108-P Data Logger

Measuring Wind Speed Using an Anemometer with a 4-20mA Output and a DI-2108-P Data Logger

One of the most common measurements in data acquisition is that of 4-20mA analog signals. Not only are 0-20mA and 4-20mA process current measurements extremely common in industrial settings, but a significant number of flow, pressure and rate sensors also feature 4-20mA outputs. Why Choose a 4-20mA Output? Acquiring data from sensors/transducer with a voltage Read More Source: DATAQ…

Stand-Alone Date/Time Stamps in Microsoft Excel

Stand-Alone Date/Time Stamps in Microsoft Excel

A critical component of data acquisition, date/time stamps allow you to determine the status of your device under test at a particular instant in time. How that date/time stamp is displayed, and the precision (to the nearest tenth or hundredth of a second) can be quite subjective. Some like to see the date first (mm/dd/yyyy), Read More Source: DATAQ…

How to Determine Power Consumption Using a Current Probe with the DI-4108

How to Determine Power Consumption Using a Current Probe with the DI-4108

In this article, I will show you how to display and record current (Amps) using a DATAQ Instruments model DI-4108-U, WinDaq data acquisition software and a 400 Amp AC/DC current probe (Electronic Specialties Model 697). I’ll use the current information to determine how much energy is used in a typical household appliance. I chose the Read More Source: DATAQ…
