White Paper Describes Omitting Drivers from Data Acquisition System

September 26, 2022

If you are building a data acquisition system with instruments from one or more vendors, you probably expect you will need to install one or more drivers. Such drivers are operating-system-specific, so you must choose the appropriate 32- or 64-bit versions for your Linux or Windows platform, which most data-acquisition instrument makers support. What they don’t tend to support, however, are drivers for mobile operating systems, so if you want to initiate a measurement sequence to examine some acquired data using your smartphone, you’re out of luck.

White Paper Details White Goods Energy-Efficiency Measurements

June 20, 2022

Sky-high energy prices will motivate consumers to seek out the most efficient appliances. You can attract these consumers’ attention by earning, for example, Energy Star certification in the United States. Whether or not you pursue such certifications, the United States, the European Union, and other jurisdictions require that you include a label on your white-goods product indicating its efficiency relative to competitive products. To substantiate your product's rating, you will need extensive data sets—representing voltage, current, temperature, humidity, and other parameters.

Focus on Operating Cost Savings when Choosing a High-Channel-Count DAQ System

April 27, 2022

Operating expenditures can be substantial over the operating lifetime of a high-channel-count data acquisition (DAQ) system. Consider all the aspects that can contribute to operating costs, ranging from setup and wiring to expenses you can incur if a lengthy test needs to be redone because of a faulty sensor or a network crash. When choosing a DAQ system, carefully evaluate how you can significantly reduce such operating costs with a very slight increase in up-front capital expenditures—in short, nudge up CAPEX to slash OPEX.

Improve Your Data Acquisition with AMETEK Programmable Power’s Complete Guide to Better Measurements

June 24, 2021

You need better sensors. Why? Because a single bad sensor could cause your functional tests to fail, wasting millions of dollars if you are testing something like a missile or a jet engine in a one-shot destructive test. A failed test is not even the worst-case scenario. Imagine what is at stake if a bad sensor gives you a false positive, leading to your device failing out in the field – all of which could have been avoided by getting the right sensors.

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.
