Wireless Strain Measurements with iTestSystem, LabVIEW, and Arduino

On a recent project, one of our engineers needed to measure structural strain at several locations on mobile lifting equipment while in operation. Since the strain measurements were distributed and mobile, a wireless internet of things (IOT) solution was required. This blog describes the steps and tools we used to integrate our solution into iTestSystem […]

Another Successful Condition Monitoring System Installation

Last week our team successfully and safely installed another Boiler Monitoring System (BMS).  This system, a Sootblower Fouling Detection (SFD) system, monitors structural and vibration sensors that quantify the boiler’s response to sootblower operations. The SFD system analyzes the boiler response data and outputs Key Performance Indicators (KPIs) such as fouling level, sootblower efficiency, and […]

FFFFFantastic ITM Team Building Weekend: Norris Lake, TN

ITM held its an annual team building over the weekend of October 11th; fun, fish, food, fire, and firsts ensued. I would like to thank ITM owner Tim Carlier and our host Ryan Welker for a fantastic weekend at Norris Lake, TN.  It was great to hang out and get to know our team outside […]

Troubleshooting Machine Failures Caused by Intermittent Damaging Events

Over the years we have been tasked with identifying the root cause of machine structural failures. In many cases, we can determine the failure mode through strain and vibration testing, order analysis, modal analysis, and operating deflection shape analysis.  What tests can you run when the damaging conditions are intermittent and not easily identified? In […]

Roving Accelerometer Impact Tests with iTestSystem

In order to prevent or troubleshoot structural vibration problems, it is important to characterize a structure’s dynamic behavior using both experimental and Finite Element Analysis (FEA) technologies.  One method used to identify a structure’s vibration modes is to perform a roving accelerometer or roving hammer impact test.  In an impact test, engineers measure the response of a structure from an impulse delivered by a […]

ITM adds FieldDAQ Sound & Vibration Module compatibility to iTestSystem

The FieldDAQ™ FD-11634 sound and vibration input module from National Instruments (NI) can now be used with the latest version of iTestSystem.  The FD-11634 is similar to the NI-9234, NI-9232, NI-9231, and NI-9230 cDAQ dynamic input modules and can be used with IEPE type sensors such as accelerometers and microphones.  Like the other FieldDAQ™ modules, this module […]

ITM @ VIATC 2019: Vibration Institute Annual Training Conference

Come see us at the VIATC 2019 Exhibit Hall in Booth 33! Ryan Matthews and Mark Yeager (CAT III Vibration Analysts) will be there to answer questions about our iTestSystem engineering measurement platform, our on-site testing services, LabVIEW consulting, and strain gauging services. When: July 24 & 25th Where: The VIATC 2019 conference and exhibit […]

Strain Gauge Shunt Equivalent Calculations in iTestSystem

When making strain measurements it is important to perform a shunt calibration both before and after the actual measurements are acquired.  Shunt calibrations ensure accurate strain measurements by adjusting the sensitivity or gain of the data acquisition equipment to compensate for leadwire resistance and other scaling errors. iTestSystem takes advantage of the shunt calibration circuits […]

Developing Custom Applications for iTestSystem

As the global market moves steadily in the direction of increased productivity through integration of software into the world of testing services, Integrated Test & Measurement finds itself at the forefront of the field.  Our other LabVIEW developers and I have been hard at work creating custom applications to help customers meet their testing needs with […]

Building a Modern User Interface in LabVIEW

When we develop LabVIEW™ applications for our customers, a common request is for a simple, resizable and intuitive user interface (UI) for data visualization.  In these cases, we use a tree control and a subpanel.  This type of UI functions like a tab control that automatically resizes.  The main benefit of using a subpanel is […]
