Understanding sensors is vital to getting good data – and good results
In an era of powerful engineering analysis software, obtaining results has never been easier, but is the data always reliable?
Modern acquisition systems and user-friendly software tools have made it simple for engineers to capture and interpret data. However, that simplicity can mask critical errors. Just because software processes data doesn’t mean the input was correct. In fact, without a solid understanding of sensor behaviour and system setup, data can be misleading, potentially leading to poor decisions in product design, safety, and performance.
Historically, engineers developed deep, intuitive knowledge of their tools and systems — a “gut feel” that flagged when something didn’t look right. This experience was passed on through hands-on learning, mentoring, and technical training. But today, as complexity increases and automation grows, that experience gap can widen.
At DJB Instruments, we specialise in vibration sensors — accelerometers — and understand just how easily measurement errors can occur due to poor sensor setup. Mistakes such as incorrect mounting, cross-axis loading, bad cabling, or outdated calibration can introduce up to 35% error in both amplitude and frequency. That level of deviation can compromise an entire test programme.
To address this, DJB has spent years delivering hands-on training for engineers at all levels, both onsite and at our factory in Mildenhall, Suffolk. These sessions have focused on real-world practices for getting the most accurate data from accelerometers, free from sales pitches and full of practical takeaways.
Training is a chance to take a step back and really consider the fundamentals,” said DJB’s Managing Director. “We’ve seen fantastic feedback from engineers across the UK, the US, and India. The opportunity to see accelerometers being built really opens people’s eyes to their importance in the measurement chain.
Although DJB is not currently running scheduled training events, we remain committed to sharing our expertise. We regularly work with customers to deliver custom sessions on topics such as sensor selection, mounting techniques, and signal integrity — either onsite or online. Webinars and in-house demonstrations are also available on request.
We’re always happy to explore opportunities for future training events. If you or your team could benefit from learning more about accelerometers and best practices in data acquisition, please get in touch.
