How to Make Safe and Accurate Thermocouple Measurements Using Isolated Instrumentation
Data Acquisition > Thermocouple > DI-1000TC Thermocouples are the most widely used devices for temperature measurements. They are: Rugged; Inexpensive; Simply constructed (welded wires composed of dissimilar metals); Used to measure temperature ranges spanning thousands of degrees; Fast in their response to changes in temperature. But these attractive characteristics do not come without a price. Read More
What You Really Need to Know About Sample Rate
Data Acquisition > Software > WinDaq By and large discussions of sample rate are like watching paint dry. Do we really have to get into the details? After all, everyone knows that you only need to sample at twice the frequency of your signal of interest to get good results, right? If you answered “right!” 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
Bandwidth and DI-8B/DI-5B Series Signal Conditioning Modules
Data Acquisition > Mixed Measurements Suppose you’re browsing the DATAQ web site looking for a DI-8B series, analog voltage module to acquire a 10V peak-to-peak, 100Hz waveform. You come across the DI-8B31-02. It’s an analog voltage module; it has a full scale measurement range of ±5V, perfect. Not so fast! The DI-8B31-02 has a bandwidth Read More
USB or Ethernet: Which Do I Choose?
Data Acquisition > USB or Ethernet When deciding between a USB and Ethernet interface, it’s important to weigh the advantages and disadvantages of both. In this application note I’ll outline the benefits (and drawbacks) of each interface; helping you to choose the best product for you’re application. When it comes to an instrument with a Read More
Thermocouple Measurements Profile Cement Curing Characteristics of Prosthetic Implants
Data Acquisition > Thermocouple > DI-1000TC Introduction It’s obvious that prosthetic implants have changed the lives of countless thousands for the better. Knee, hip, and shoulder replacements are common surgeries today, substituting diseased or damaged joints with synthetic materials that allay pain and simultaneously restore mobility and quality of life. Not as obvious is the Read More
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 Additional Reading: 4-20 mA Shunt Resistor and Current Loop Data Acquisition Products 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 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
