DATAQ Instruments Application Notes and News
Synchronized and Distributed Data Acquisition Using DI-1000 Instruments in Hot Strip Steel Mills
Data Acquisition > Thermocouple > DI-1000TC Background The need for data acquisition in a distributed and synchronized manner is required in a variety of applications. Consider a hot strip mill that creates a long steel coil starting from a slab of steel. The process consists of: A pre-heat procedure that heats the initially cold slab Read More
How To Determine 4-20 mA Loop Load
Data Acquisition > Current Additional Reading: 4-20 mA Shunt Resistor and Current Loop Data Acquisition Products Process current (4-20 mA) measurements are popular with DATAQ Instruments’ customers, and that often leads to some interesting application questions. One of the better ones relates to how many process current instruments can be connected to a single current Read More
Networked Data Acquisition Using WinDaq Software
Data Acquisition > Software > WinDaq Using WinDaq software and the client networking capabilities built into all Windows Operating Systems, you can monitor acquired data remotely in virtual real time via the WinDaq Waveform Browser (free download!). You can monitor a single data acquisition device or several simultaneously from the comfort and safety of your Read More
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
