About DJB

We have been a British leader and manufacturer for over 40 years, proudly achieving a substantial range of quality accelerometers and vibration testing equipment.

DJB manufactures accelerometers, cables and, instrumentation including a unique water-cooled triaxial IEPE accelerometer (upto 900°C). DJB is the only manufacturer using the patented Konic Shear design.

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.

Big enough to meet your needs. Personal enough to care.

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.

Accelerometers can last for decades if treated properly. However, regular calibration is important as performance will change with age. We have a state-of-the-art in-house calibration and measurement facility providing calibrations to traceable National Standards. We calibrate both charge and IEPE accelerometers as well as signal conditioning equipment for all manufacturers. 

We offer a bespoke cable assembly service and a vast range of cables including low noise and armoured solutions. There are a wide variety of connectors from off-the-shelf to bespoke in-house manufactured.
