The customer uses microphones, accelerometers, thermocouples & pressure transducers to measure brake squeal events. A Prosig P8020 is used to capture and analyse all squeal events over a two hour road course. Sophisticated pre- and post-trigger and data visualisation in DATS achieves a better understanding of brake squeal. The Prosig system was selected after similar, competitive systems were unable to cope with the environmental and capture/analysis requirements.
The digital control lines from the firing control sequence from solid propellant rocket motors are used to control a Prosig P8048, which measures vibration and pressure signals. The P8048 system is configured with a digital control module and custom acquisition software for transducer calibration, automatic data structuring and rocket test sequence measurement.
A Prosig P8004 and the DATS Human Biodynamics Analysis Suite is used to make assessments on the exposure of the human body to vibration data. The data is captured on a moving train. Health and comfort criteria are calculated according to various ISO standards and provided to the user in the form of standard reports. The end-user has used many of the results in expert testimony work in legal cases.
A Prosig system is used to simultaneously capture CAN-bus data and vibration signals on an industrial robot. The robot is controlled by a CAN-bus and the Prosig P8000 measures the relationship between sending commands to the robot and seeing the vibration effects caused by the displacement of the hydraulics. The combination of CAN-bus and vibration measurement make the P8000 an ideal fit for this application.
A high channel-count P8048 system is used to capture the vibration signals from an aircraft model sited in a wind tunnel that can operate at temperatures as low as -261C and flow speeds as high as Mach 1.3. Strain and acceleration measurements at various locations on the body of the model are taken over a preset range of tunnel conditions. An additional 8-channel Prosig system monitors the real-time forces and moments experienced by the balance gauge mounted inside the model.
The customer uses a Prosig P8004 connected to a custom triaxial accelerometer to study tarmac surfaces. As a car moves over a road it causes a ripple in the road surface. DATS is used to derive displacement from the measured accelerations. The results are used to study different types of surface and changes due to humidity and temperature. The goal is to find a surface that does not flex and break, but is not too rigid.
Prosig have supplied a turnkey industrial monitoring system that measures the accuracy of an innovative new design of domestic water meter. A P8020 system is used to capture pre-conditioned fluid pressure waveforms together with other test rig control parameters such as temperatures and pressures. Advanced pulse analysis software in DATS analyses the captured signals and produces detailed reports that compare meter performance at different flow rates under various test conditions.
A weight is dropped on to a motor cycle helmet mounted on a dummy head. The acceleration of the weight and helmet is measured. Different accelerations profiles must be achieved for different test standard. The DATS Biomechanics software is then used to check if test has met the required profile and to verify whether the helmet meets the necessary standards.
The customer needs to check whether noise and vibration from an underground train line is going to cause a nuisance in a proposed multi- storey housing block. A sophisticated measuring system based on a triaxial accelerometer is connected to a Prosig P8000, which is used to capture the data. The results of further analysis are used to determine if the noise and vibration of the trains will fall within prescribed limits.
A Prosig P8000 system is used to measure vibrations at defined points on a seat designed for commercial / industrial / agricultural vehicles. The seats are tested on a 3-axis shaker rig while suitably loaded. The DATS Human Response software is then used to check that the seat complies with the relevant standard.
