ITM can develop a real time vibration and health monitoring system for validation and testing of generator sets. Our Genset Vibration Systems can acquire, analyze and report the vibration levels recorded around a generator set structure. By identifying and fixing structural flaws of generator sets earlier in the process, we can help you create higher quality products for your customers. The flexibility and quality of the NI CompactDAQ platform combined with our proprietary iTestSystem software allows us to build a custom and high-performance test system for customers in a short amount of time, saving substantial costs.
As an example, our customers may need a reliable system to test the vibration levels of its generator sets prior to field deployment so they can validate their design and manufacturing. They also may want the test system to record synchronized, high-speed data that could be used by engineers to troubleshoot structural problems if any occur. By leveraging integrated hardware from NI, we are able to provide our customers with a solution that enables their test cell technicians to measure structural vibration levels safely, quickly and efficiently.
Genset & Rotating Machinery Vibration Level Testing
ITM’s Genset systems typically consist of a real time controller enclosed in a stainless steel enclosure and 4 triaxial accelerometers. In one such use case, we used a National Instruments (NI) CompactDAQ Ethernet chassis (cDAQ-9189) with 8 dynamic signal acquisition (DSA) input modules, NI 9234 and NI 9229, to condition, synchronize and digitize the acceleration and voltage signals. The NI 9234 module was connected to accelerometers for collecting accurate high-speed vibration measurements. The NI 9229 module was connected to a magnetic pickup sensor to determine the rotational speed of the generator. We chose the NI 9229 module because it combined a high resolution with a wide voltage range, and was able to be synchronized with the NI 9234 module. We chose the NI cDAQ-9189 Ethernet chassis with Ethernet connectivity because the test cells had an existing Ethernet network. We used our configuration based data acquisition and analysis iTestSystem software, which was built using NI LabVIEW system design software, to acquire and view the vibration data generated by NI cDAQ hardware. We also created a custom plug-in for iTestSystem that generated vibration reports and animated vibration modes.
