Our test engineers are often called upon to deploy unattended or “black box” data acquisition systems in the field.Ā These systems are deployed on machinery, vehicles, and industrial processes to constantly record strain and vibration data at sample rates between 100 and 100,000 Hz. That adds up to a lot of data to sift through. […]
Today, most high-end data acquisition equipment manufacturers provide signal conditioning options for collecting data from single strain gauges.Ā Signal conditioning for strain gauges usually includes circuitry for bridge excitation voltage, quarter and half bridge completion arrangements, and shunt calibration. What we offer Are you looking for expert assistance with accurately measuring stress and strain? or, […]
I want to congratulate my colleague Ryan āRJā Matthews on a job well done as he recently administered ITMās annual safety training.Ā RJ did an excellent job presenting the material and addressing questions. His efforts will certainly help us stay focused on our vigilance toward workplace hazards. For strain gauging or test services, contact Ryan […]
Choosing an accelerometer for rotating machinery vibration measurements can be a daunting task since there are so many options available. This blog outlines the characteristics you should consider when choosing a piezoelectric single axis accelerometer for general purpose vibration measurements and presents some accelerometers to consider. Characteristics of a General Purpose Accelerometer When measuring vibration […]
ļ»æļ»æ Our test engineers collect vibration data on rotating machinery using four basic tools.Ā We use a Laptop computer with iTestSystem software to stream accelerometer and rotational/speed pulse sensor data from a National Instruments cDAQ equipped with vibration and voltage input modules.Ā The video above shows how to collect vibration data using iTestSystem and a […]
ļ»æļ»æ 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 […]
ļ»æļ»æļ»æ Last week our team successfully and safely installed another Boiler Monitoring System (BMS).Ā This system, a Sootblower Fouling Detection (SFD) system, monitors structural and vibration sensors that quantify the boilerās response to sootblower operations. The SFD system analyzes the boiler response data and outputs Key Performance Indicators (KPIs) such as fouling level, sootblower efficiency, […]
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.Ā It was great to hang out and get to know our team outside […]
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.Ā What tests can you run when the damaging conditions are intermittent and not easily identified? In […]
In order to prevent or troubleshoot structural vibration problems, it is important to characterize a structureās dynamic behavior using both experimental and Finite Element Analysis (FEA) technologies.Ā OneĀ method usedĀ to identify a structure’s vibration modes is to perform a roving accelerometer or roving hammer impact test.Ā Ā In anĀ impact test,Ā engineers measure the response of a structureĀ from anĀ impulseĀ delivered byĀ a […]
