Advanced engineering benefits from highly accurate and reliable data acquisition equipment
HBM will showcase its extensive range of DAQ equipment on stand D96 at this year’s Advanced Engineering show. Key personnel will be available to demonstrate the latest products that meet the demands of high-quality engineering in the aerospace and automotive sectors for the swift and accurate capture of data combined with analysis, often in real-time, to ensure maximum efficiency.
HBM will demonstrate its CANhead channel system that is primarily aimed at the aerospace sector for measuring strain or force. The measuring chain includes HBM’s CANhead distributed amplifier system, U10M force transducers and the MGCPlus. The 10-channel CANhead amplifier modules can be installed in immediate proximity to measuring points while standard fieldbus cables connect the CANhead modules to a communication master.HBM has improved its U10M force transducer with IP68 degree of protection making the transducers suitable for use in challenging ambient conditions. The cable is connected directly to the transducer contrasting with other models that utilise a bayonet-type plug.
Electric Drive Vehicles
HBM will also feature the eDrive testing system developed around its GEN3i data recorder, T12 torque transducer and 1KV data acquisition card to measure torque, speed and electrical signals. HBM developed the eDrive concept to overcome the disadvantages of common methods currently in use by providing engineers with improved test and measurement equipment for a new approach to increased efficiency. The system ensures the continuous storage of raw data allowing live analyses for determining active and reactive power as well as energy conversion efficiency and further, more detailed analyses.
HBM’s mobile GEN3i data recorder can transfer data directly to the storage medium at speeds as high as 200 MB/s while up to 96 input channels can be configured as required. Data can be continuously transferred to hard disk and fast sweeps recorded so that users benefit by recording, saving and visualizing millions of measurement data items per second.
The 1 kV data acquisition card for HBM’s Genesis HighSpeed measurement systems enables very accurate and rapid measurement of voltages from ±20 mV to ±1000 V signals with a measurement accuracy of 0.1%.
Measuring torque and rotational speed will be demonstrated utilising a radial engine fitted with HBM’s T40B digital torque flange combined with aTIM-ECA interface and a Beckhoff controller. The T40B digital torque flange from HBM gives speed measurements along with direction of rotation monitoring in addition to torque measurement in one compact system.
This is a robust system enabling very accurate measurements even under difficult industrial ambient conditions. The torque flange is available with nominal torque ranges from 200 Nm to 10 kNm while the integrated speed measurement system generates 1,024 pulses per revolution, thus enabling very accurate speed measurements even at low speeds.
The TIM-EC interface with digital data transmission enables torque and speed to be precisely acquired simultaneously and integrated in real-time in control and automation systems. TIM-EC supports sampling rates of up to 20,000 measured values per second on the bus. Signals are transmitted digitally and without loss of accuracy and both the angle of rotation and the performance can also be captured.
Force & displacement
Force and displacement will be measured with an eccentric press featuring HBM’s PMX data acquisition and control system combined with the U9 force transducer. HBM set industry standards with its PMX data acquisition and control system. The PMX enables the precise acquisition of many quantities including force, torque, vibration, angle of rotation and rotational direction. It has 16 measuring and 32 calculating channels with each channel rated at 38,400 samples per second while the PMX, as a whole, is rated at up to 400,000 values per second.
HBM has recently launched hermetically welded upgraded versions of its U9C miniature force transducer with IP67 degree of protection as standard. They feature an accuracy class of 0.2 that is a marked improvement compared with the previous version. Each of the models is available in ten measurement ranges from 50N to 50kN.
Another demonstration will feature a Ball Drop Test that is used to determine the force and mass of an object. This demonstration will feature HBM’s Gen3i and the MX410 combined with the U10M. HBM’s mobile GEN3i data recorder can transfer data directly to the storage medium at speeds as high as 200 MB/s while up to 96 input channels can be configured as required. The data recorder is capable of a wide range of data acquisition and analysis work with its integrated Windows 7 PC and preinstalled Perception software.
HBM will also be giving presentations during the show. On Tuesday, 11 November, Karl-Heinz Haase, Product Manager for Optical Strain Gauges and Interrogators will look at determining the strain in composite and lightweight materials with his presentation on “The Benefits of Fibre-Optical Technology in Structural Testing of Lightweight Materials”.
This presentation will be complemented the following day when visitors interested in developments impacting on the aerospace sector will be able to attend a presentation on “How to Guarantee Fatigue Strength in the Aerospace Industry Today – With Shorter Development Cycles and Increasing Quality Standards” which will be given by Jens Boersch, Product Manager – Electrical Strain Gauges and Accessories.
Founded in Germany in 1950, HBM is today the technology and market leader in the field of test and measurement. HBM’s product range comprises solutions for the entire measurement chain, from virtual to physical testing. The company has production facilities in Germany, USA and China and is represented in over 80 countries worldwide.
