RSS FeedsData Acquisition > Thermocouple > DI-245 The ability of the DI-245 and DI-2008 to reject common mode voltage is unmatched in the $75 per channel price range. To demonstrate the ability of the DI-245, where DI-2008 shares the same front-end configuration, to reject common mode (error) voltage, we connected K-type thermocouples to channels 1 and Read More

Introducing the DI-245 Voltage and Thermocouple Data Acquisition System
Data Acquisition > Voltage > DI-245 DATAQ Instruments is pleased to introduce the all-new DI-245 Voltage and Thermocouple data acquisition system. The DI-245 provides four analog inputs that can be individually configured to measure voltage or thermocouple data. With 12 programmable measurement ranges from ±50V to ±10mV, the DI-245 provides resolution up to 1.2µV. The DI-245 Read More
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 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
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
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
Maximum Thermocouple Wire Length
Data Acquisition > Thermocouple We commonly hear, “What’s the maximum thermocouple wire length I can use with your instrument?” That’s a good question. There are two factors that affect TC cable length: 1. Noise 2. Inaccuracy The longer the cable the more susceptible it is to radiated noise. The TC represents a low impedance source, Read More
