DATAQ Instruments Application Notes and News

Sub-zero Thermocouple Measurements

Data Logger > Thermocouple “One of the best kept secrets in the instrumentation world is that sub-zero thermocouple measurements require thermocouples that are specially qualified for that application.” Looking at the specs of a typical thermocouple data acquisition system might be a little misleading when it comes to interpreting temperature measurement capability. For example Figure 1 is a Read More

How To Power Multiple 4-20 mA Sensors

Data Logger > 4-20mA Process Current We’re often asked how to power multiple 4-20 mA sensors using a single power supply. While it is possible to do this, the usual cautions apply regarding ground loops and other subtleties. Readers who are new to measurements using sensors with 4-20 mA process current outputs should refer to our Read More

Active USB Extension Cables Limit Data Loss

Data Acquisition > USB Perhaps you have an application that requires your USB-connected data acquisition system to be positioned further from the PC than the 2 to 5 meter maximum USB cable length specification. The USB Active extension cable allows you to position your USB-connected data logger up to 15 meters (almost 50 feet) from Read More

Changes to the Built-in Temperature Alert Server

Data Logger > Wireless > Temperature Alert There have been some changes to the server, built into the Temperature Alert TM-WIFI350 LAN-based temperature and humidity data logger. In the past, when typing the IP address of your TM-WIFI logger into a web browser, you were directed to ‘Developer Mode’. In Developer Mode you can set alarms, Read More

Flood Sensor for Temperature Alert

Data Logger > Wireless > Temperature Alert The AC-FLDRJ is a flood sensor designed for use with the Temperature Alert TM-WIFI-350 LAN-based temperature and humidity data logger. Measuring just 2.5” x 3.25” x 1”, simply lay the sensor on a flat surface to detect the presence of conductive, non-flammable liquids. Built-in feet on the bottom Read More

Trouble Communicating With Your Ethernet Connected DI-720 or DI-730 EN-B

Data Acquisition > Ethernet On This Page Symptoms Cause Resolution Verify that you’re installing the latest version of WinDaq Verify that your Network Interface Card (NIC) has a static IP address Disable any wireless connections Verify Windows Firewall settings Run the DATAQ IP Manager as an administrator Make sure that your Ethernet cables are not Read More

Die Cushion Qualification

Data Acquisition > Mixed Measurements DATAQ Instruments was recently mentioned in Evaluation Engineering magazine‘s special report on data acquisition systems. The feature focused on applications in machine condition monitoring, which is an area that is very popular for users of our equipment. So, we thought we’d publish an overview of it here for our readers. The specific Read More

WinDaq/XL Real-time Bridging Software

Data Acquisition > Software > WinDaq > Add-ons WinDaq/XL is real-time bridging software that allows users to stream data from WinDaq data acquisition software or the WinDaq Waveform Browser, into a Microsoft Excel spreadsheet. Once there, users can take full advantage of Excels exceptional ability to perform calculations and chart data. Since it’s initial release Read More

WiFi Range Considerations

Data Logger > Wireless We carry several WiFi products and we’re often asked about their range. In other words, how far from the WiFi router can the data loggers be located? Unfortunately, this is like asking us to forecast the weather next Sunday. There are simply too many variables for us to predict how well any WiFi Read More
