3 Tips for Maximizing Thermocouple Measurement Performance

June 10, 2020

Thermocouples are without a doubt the most popular type of temperature sensor, and the VTI Instruments EX1000A Precision Voltage Measurement Instrument Series provides 48 voltage channels and supports Type J, K, T, E, S, R, B, and N thermocouples. To help you avoid some common pitfalls when making thermocouple measurements and get the most out of your instrument, we offer the following tips:

Transducer Electronic Data Sheets Simplify Sensor Setup

December 5, 2019

Testing that requires the use of strain gages often consume large amounts of resources and effort to prepare for. One way to reduce the amount of time and energy spent configuring a test is to use sensors that support the Transducer Electronic Data Sheet (TEDS) interface. Many VTI measurement instruments support TEDS sensors including the EX1629 48-channel high-performance strain gage measurement instrument, EX1403 16-channel bridge/strain gage instrument, and the RX1024 24-channel bridge/strain gage instrument.

How To Select Thermocouples for Temperature Measurement Systems

November 4, 2019

For many test applications, measuring the temperature is a necessity. For example, when testing an aircraft engine, you may need to measure manifold temperature or the exhaust gas temperature. To help you take those measurements, VTI Instruments offers a number of options, including the EX1000A series of precision voltage measurement instruments and the RX1032 rugged thermocouple measurement system.

Thermocouples are arguably the most common type of temperature sensor, although you can also use resistance temperature detectors (RTDs), or thermistors. The EX1000A series supports all three types of sensors, while the RX1032 supports only thermocouples.

Are IVI Instrument Drivers Compatible with Linux?

May 13, 2019
Topics:

A question that we often get is whether or not the IVI instrument drivers that we supply with our VTI Instruments products are compatible with Linux. The reason for this question is that many users prefer to have complete control over the software of their test system. And as a result, prefer to use Linux over Windows as their test system’s operating system. For users of LXI instrumentation, the question becomes whether or not the IVI instrument driver that comes standard with their LXI hardware work in Linux.

Decreasing Test Time in High-Channel-Count Applications


When performing functional tests, keeping test times as short as possible is often a critical requirement. Time is money, after all. One way to reduce test times is to reduce the latency in setting up signal switch paths, stimulus devices, and measurements. These can all have a significant impact on the overall time it takes to complete a full functional test of a particular DUT.

DAQ System Provides Data Redundancy for Automotive Tests

January 31, 2019

The automotive market is a highly competitive and complex business. In order to be competitive, vehicles must not only offer comfort and top-notch features at a cost-effective price but also ensure passenger safety. Long before any new model goes into mass production, a long series of sophisticated tests and validations are required at various stages to ensure that the vehicle meets all governmental standards and company performance standards.

Vehicles are often operated under test conditions for weeks or months, which requires logging and archiving massive amounts of data. In addition, in-vehicle tests often require the use of portable test systems, which are ideally compact, rugged, light in weight and free standing. Given the limited space within the vehicle, they typically must operate wirelessly with no connection to a computer. These in-vehicle datalogging systems must be compatible with a wide array of sensors.
