About us

DJB Instruments UK Ltd has been manufacturing IEPE & charge accelerometers, cables, instrumentation, and accessories since 1974.

Why choose DJB?

DJB has been manufacturing IEPE & charge accelerometers, cables, instrumentation, and accessories since it was established as DJ Birchall Ltd in 1974. Its acquisition by CMTG in 2021 began a fresh era of growth and brought a renewed focus on quality, customer care and innovation.

DJB is the only global accelerometer manufacturer using the patented Konic Shear™ design, which offers significant performance improvements and cross-axis reduction. We manufacture several unique products such as a water-cooled triaxial IEPE accel capable of testing up to 900°C, high temp IEPE up to 185°C, and one of the world's smallest IEPE accelerometers weighing just 0.19g. 

Based in Mildenhall, Suffolk, the company supports world-class test & measurement and conditioning monitoring solutions across the automotive, aerospace, power generation, advanced engineering, defence, and manufacturing industries. The company’s products are sold from our UK headquarters and CMTG facilities in France, Italy and the USA. We have partners in China and India and resellers throughout the world.

We are responsive to requests for bespoke sensors and cables. As a manufacturer, it is easy for us to provide prototypes and final products to suit any customer application.
