DATAQ Instruments Application Notes and News

USB-to-Ethernet Adapters

Data Acquisition > Ethernet USB-to-Ethernet adapters make it possible to connect a DI-720/730 EN-B product to your PC via USB 2.0. These affordable, easy to install adapters are ideal for customers who either don’t have an available Ethernet port or are more comfortable connecting via USB. Installation takes 60 seconds or less and once installed Read More

4-20 mA Current Loop Data Acquisition

Data Acquisition > Current One of the most common industrial measurements is 4-20 mA current loop data acquisition. Electrical noise, present in most industrial settings, makes measuring a sensor/transducer output as a voltage impractical—especially over long distances. The solution is to transmit the sensor/transducer output as a current signal (process current). This is achieved by Read More

How To Connect and Calibrate Thermocouples Using DI-8B47 Series Amplifiers

Data Acquisition > Thermocouple Thanks to the American National Standards Institute (ANSI), thermocouple wire is color coded to indicate thermocouple type and polarity. This takes the guesswork out of connecting thermocouple wires to your DI-718B, DI-718Bx, or DI-788. In this example, we’ll show you how to connect and calibrate a K-type thermocouple using a DI-718B, Read More

How to Manage Dynamic IP Addresses In Data Acquisition Applications Over the Internet

Data Acquisition > Ethernet Introduction One of the most exciting applications for DI-71X (DI-710, -715B, -718B) Ethernet products is to acquire data from anywhere in the world over the Internet. Although setting up IP addresses is a straightforward procedure in this situation, the approach potentially suffers from one troubling flaw: IP addresses assigned by an Read More

IP Address Configuration for DI-71X-E Data Loggers

Data Acquisition > Ethernet DI-71X Ethernet data loggers and WinDaq Data Acquisition software make data acquisition over any network a snap. You can access your DI-71X Ethernet device over a local area network, remotely over a sub-network through a router or even over the internet! In this application note I’ll outline the basic networking principles Read More

Clutch Testing with Data Acquisition Products

Data Acquisition > Mixed Measurements Our customer, a manufacturer of clutches used in a variety of small and large vehicle applications, wanted to replace his aging test instrumentation. Consisting of a 20-year old Gould Mark 200 chart recorder and associated amplifiers, the old equipment was breaking down frequently, difficult to repair, and expensive to maintain Read More

ActiveX Controls for Data Acquisition Applications

Data Acquisition > Software > Active X This tutorial will show you how to use the activeX controls named XControls in Excel with WinDaq/XL. WinDaq/XL is DATAQ’s software add-on to WinDaq/Lite, /Pro, and /Pro+ that allows data acquired by these packages to be ported to a Microsoft Excel spreadsheet. Let’s say you need to measure Read More

How to Store Data using WINDAQ MySQL
