They key to accurate force measurements is precise calibration, and the key to precise calibration is – besides suitable calibration equipment – traceability, which, in turn, refers to the connection of the measured value to the recognized national standard by a continuous chain of comparison measurements with known measurement uncertainty.

Traceability is also required to meet the ISO 9001 or IATF 16949 standards and is thus relevant for audits – whether they stem from internal quality departments or from customers.

So how can we, as HBK, make sure that we supply customers with force measurement technology that not only shows the correct values, but also meets all legal requirements? Watch Thomas Kleckers’ presentation and find out more about calibration. You will discover:

– How is it guaranteed that the newton measured is actually a newton
– How to bring traceability to your application
– How quality audits and traceability are interlinked
– How this is related to the PTB or other national metrological institutes

The path to converting information into a digital format is not easy for small and medium-sized companies. For that reason, one of five IIoT competency centres for medium-sized businesses funded by the German Federal Ministry of Economics, was set up at Darmstadt Technical University (TU). Here, companies can learn about the methods used to achieve digitization.
In this presentation we demonstrate:

– A key element of this networked production is the control of the measurement chain in which the data of all sensors in use comes together and is processed
– The industrial amplifier is one of many devices from different manufacturers that bring digitized production on the university campus to life and is especially well suited to upgrading existing production chains
– The Presentation will highlight the CiP (Industrial productivity center) at the university, with two use case: predictive maintenance and digital shop floor management

The use of smart measuring amplifiers is essential in the course of implementing Industry 4.0 concepts. Intelligence must already be present directly in the component – “edge computing” in order to be able to process data efficiently and in a targeted manner. The possibilities offered by the introduction of IIoT (Industrial Internet of Things) into productions are extensive. The aim is to gain more control over the process and thus to guarantee the quality of products and increase yields.

In this presentation we demonstrate:

– Optimize processes, reduce costs and expand productivity
– Requirements of modern measurement hardware in times of the IOT
– Differences between PLC- , Software- , and Cloud-applications
– Ensuring interoperability through suitable protocols
– Hardware and software solutions in a LIVE demo

Reliability is the degree of consistency of a measure. A transducer is reliable when it gives the same repeated results under the same conditions. If a transducer is not reliable, its measurement results will never lead to correct conclusions.

Therefore, the reliability of a transducer is one of the utmost importance to anyone involved in test and measurement. Unfortunately, reliability is not a specification that is listed on a product data sheet. So, how can you ensure the reliability of your transducers and be confident with the accuracy of your measurement results?

The presentation will cover:

– How to ensure reliability based on the transducer design
– How to ensure reliability based on the transducer’s production processes
– What you can you do to reinforce the reliability of your transducers

When it comes to headphone measurements, finding correlation between the measured results and subjective observations is often elusive. There are a number of reasons for this, including challenges achieving a human-like fit (especially with supra-aural and in-ear headphones), but also that the hearing simulators we have been using are based on a 40-year-old standard that does not simulate human hearing over the entire audio band.

In 2017, Brüel & Kjær introduced a new standard for hearing simulation based on 12 years of research and development, intended to provide unprecedented realism. The Brüel & Kjær HF-HATS (High-frequency Head and Torso Simulator) Type 5128 provides an accurate simulation of human hearing by more accurately modeling human geometry and acoustic impedance from the pinna to the eardrum.

This presentation will include examples of how this more accurate hearing simulator will help close the gap between the headphones as we hear them and the headphone measurements we look at.

Compressed air is used for multiple systems in a locomotive and in railcars. The brakes on train cars are actuated by this compressed air system. These air lines can extend for miles down long trains and large leak volumes, which mean additional energy and fuel costs for operators. Presently, leak detection is completed by manual inspection while trains are parked in rail yards, meaning only the largest leaks are detected. With better detection methods, moderate leak sources could be identified and corrected, leading to large energy savings for rail operators. Southwest Research Institute first demonstrated with a microphone that these air leaks have a high frequency acoustic signature that can be measured in a noisy environment. SwRI then used an acoustic camera and was able to identify air leaks in both a stationary and moving locomotive. These leaks generate a broadband noise signature that extends well into the ultrasonic range, above the frequency range of other noise sources generated by a locomotive. This signature allows the leak source to be identified even with large levels of background noise, such as the engine running under high load. Coupled with machine learning algorithms, this tool could be used on wayside monitoring stations to automatically detect air leaks and feed that information back to the rail operator.

A large inline-6 cylinder engine of 170 liters displacement was recently run through an emissions deterioration factor test at a facility using an open stack exhaust system (no muffler). Normally, a 4-stroke cycle I-6 produces pure tone noise at firing frequency (every 120 degrees of crank rotation, or 3rd order), as well as at harmonics of firing frequency. This engine produced a very uneven sound that was audible for up to a mile from the test site. The character of the sound left observers wondering if there was something wrong with the engine. Acoustic measurements confirmed that there were substantial noise spikes at almost every multiple of half order. Further evaluation revealed that the unusual sound spectrum is a result of the large physical dimensions of the engine. With the engine’s turbocharger located at the front of the engine, the distance from each cylinder to the turbocharger and the time it takes sound to travel the length of the exhaust manifold become important. With some assumptions about exhaust temperature and pressure, the time (in degrees of crank angle) that is required for a blowdown pulse from each cylinder to reach the turbo can be calculated. It takes sound from the blowdown pulse of cylinder 6 about 14 crank degrees longer to reach the turbo, compared to the blowdown pulse from cylinder 1. The results explain why the engine has so much frequency content in its exhaust noise at almost every multiple of half order. This effect is common to all large engines, such as locomotive and marine engines.

Appropriate testing and measurement technology is indispensable in the course of reliable assessment of component behaviour and its functional properties as well as their lifetime. For this purpose, various requirements have to be made for the testing and measuring technology applied. The basic request is that measuring accuracy is sufficient high. The second request is that measurement must also be (long-term) stable. Third, regarding any disturbance variables, they must be of no effect on the result or to be measured in detail in order to take them into account – or correct the main result.

Predictive maintenance and process optimization are the key advantages that come with the industrial digitalization as they significantly reduce costs and enhance productivity. However, most of the existing production facilities are not suitable for a retrospective sensor integration to monitor mechanical loads during operation. We present a sensor solution based on HBM strain gauges that is integrated inside existing mechanical components of this industrial facilities, e.g. drive shafts or couplings, to monitor and analyse their mechanical states without changing the topology of the system. Since the sensitive element to measure torque, force and rotational speed is protected inside, the components are very robust against environmental influences. The wireless sensor processes all measured data on chip to analyse the current state of the process and sets an alarm if mechanical thresholds are exceeded. The measured data and component states are sent to a mobile device or industry gateway. There, the current state of the component and downstream processes can be interpreted by a human supervisor or processed by a system control. With our intuitive user guidance in a smartphone app, the force and torque measurement chain is simplified to a wide range of users without specific expertise.

The Brazilian test, which was developed in 1943, is a relatively simple method to determine the tensile strength of rock. It is an indirect test which has been standardized by both ASTM and ISRM. In the test, a compressive force induces tensile stresses along the centerline of a thin disk-shaped specimen. This test is widely performed because of difficulties associated with direct tensile testing of rock specimens where fixtures must be attached to specimens or specimens must be machined to certain shapes. The simplicity of the test has prompted the development of portable hand operated hydraulic load frames where often the only data which is recorded is the compressive force required to fail the specimen and the time it took to fail the specimen. The validity of the Brazilian test requires fracture to occur through the middle of the specimen and that there should be no visible platen effects present on the specimen. With limited data collected during tests it is easy to question their validity. More importantly, insights into the behavior of the specimen are lost. This presentation highlights the use of the QuantumX data acquisition system coupled with an acoustic emission system to assess precursors to failure during Brazilian testing of rock. One goal of the research is to capture data from the testing to calibrate FDEM models which are used to simulate the fracturing process in brittle materials.

S.O.N.I.A. AUV (autonomous underwater vehicle) is a student run robotic club from École de technologie supérieure from Montreal, Canada. For twenty-one years, we have been attending the Robosub competition yearly in San Diego. The team has been using hydrophones to locate obstacles within the reservoir boundaries where the competition takes place. The system in place for the hydrophones add in complexity and challenges to the existing system of our AUV. The effort made for having accurate data is rewarded at the competition since it can provide us with more than a third of the points obtainable. For 12 years, Brüel & Kjaer has sponsored us with the Hydrophones type 8103. Due to our mechanical design this type of hydrophone is the only one that can be mounted on our submarine. The team has for more than ten years actively developed and designed our own printed circuit board to process the signal from the hydrophones. With the accumulated data obtained our algorithms calculate the position and the heading from the obstacle.

I am a university student in automation engineering at École de technologie supérieure. I am starting my third year in my 4 years program. I have been working for the robotic club S.O.N.I.A. AUV at the start of my degree.
