Dual-Channel Wireless Temperature Data Loggers
Data Logger > Wireless DATAQ Instruments is pleased to introduce the EL-WIFI-DTC and EL-WIFI-DTP+. These dual-channel wireless (802.11b compliant) temperature data loggers are capable of buffering over 1,000,000 temperature readings and transmitting that data to a PC via a WiFi router. The EL-WIFI-DTC can acquire temperature from -270 to 1300°C (-454 to 2372°F) using J, Read More
Using Intelligent Oversampling to Extract Important Information
Data Acquisition > Software > WinDaq Oversampling is a feature whereby a data acquisition instrument can sample data at a faster rate than what is being reported in the software. Intelligent Oversampling allows the instrument to evaluate the data that isn’t being reported, and yield just the information you’re looking for (average, maximum, minimum, the Read More
DAQ Starter Kit Helps Win Science Fair Competition
Data Acquisition > Start Kits DATAQ Instruments makes data acquisition hardware (usually a DAQ starter kit) and software donations from time to time to young people who demonstrate the need for a particular measurement that we can satisfy. Examples are measurements in school projects, science fairs, and even Ph.D theses. We recently learned that two Read More
EL-USB Battery Issues
Data Logger > USB > EL-USB We’ve noticed an uptick in the number of customers reporting that the batteries included with their EL-USB series data loggers are ‘dead on arrival’. The battery included with most EL-USB series loggers is a 3.6V (½AA cell) lithium metal battery. The problem can occur when a battery is unused Read More
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
