Brüel & Kjær

What Brüel & Kjær does

Brüel & Kjær, operating today as part of Hottinger Brüel & Kjær (HBK), designs and sells integrated precision test and measurement solutions spanning three technology domains: mechanical, sound and vibration, and electrical measurement. Founded in Denmark in 1942 and subsequently merged in 2019 with German counterpart HBM (Hottinger Baldwin Messtechnik, founded in the 1950s) under UK-listed parent Spectris plc, HBK combines over 80 years of legacy from each brand and serves engineering teams in aerospace, automotive (especially electrification and NVH), defense, energy (including wind and grid), rail, robotics, audio device manufacturing, food and beverage, machine manufacturing, and logistics. Marquee deployments include Ford's global road load data management on the Aqira platform and NAVAIR's C-FRACAS+ system across 33 defense aviation programs.

The product architecture is a platform-plus-modules stack: data acquisition systems (QuantumX, SomatXR, MGCplus, LAN-XI, Genesis HighSpeed, Wireless DAQ, eGrid/eDrive power analyzers, Fusion RX/MX, Fusion-LN, NEXUS, eDAQ); a software layer (BK Connect/PULSE, Catman, Tescia, Perception, the nCode suite for durability and signal processing, the ReliaSoft suite for reliability/FMEA/RAM, Aqira for test data management, and HBK Monitor360 for AI-powered asset monitoring); a sensor portfolio (load cells, strain gauges, fiber-optic strain gauges, measurement microphones, accelerometers, force/torque/pressure transducers, IMUs/INS, and IO-Link smart sensors); integrated systems (LDS vibration shakers, HATS electroacoustic test systems, Acoustic End-of-Line test systems); and a services business covering calibration, installation, maintenance, repair, training, and materials characterization. The portfolio is delivered through an open ecosystem integrating with LabVIEW, DIAdem, CANape, ROS, and PX4.

HBK goes to market primarily through direct enterprise field sales supported by global calibration and support infrastructure, with quote-based, multi-year pricing on complex configurations and a smaller e-commerce storefront (HBK Shop) for standard products. Revenue is generated from one-time hardware sales (sensors and DAQ systems), software licenses and subscriptions (nCode, ReliaSoft, Catman, BK Connect), and recurring/ancillary services (calibration, maintenance, repair, installation, training, and materials testing). The company employs 1,001–5,000 people globally and is headquartered in Nærum, Denmark.

Revenue model

1. Hardware Products (Sensors & DAQ Systems): HBK generates revenue through the sale of precision measurement hardware including sensors (load cells, strain gauges, microphones, accelerometers, torque sensors, pressure transducers), data acquisition systems (QuantumX, LAN-XI, Genesis HighSpeed, SomatXR), and integrated measurement solutions. These are typically one-time capital purchases with varying channel counts and specifications.
2. Software Licenses & Subscriptions: Revenue from software products including BK Connect/PULSE, nCode (DesignLife, GlyphWorks, VibeSys), ReliaSoft suite (BlockSim, Weibull++, XFMEA, RCM++), Catman, Tescia, Perception, and vibration control software. May include perpetual licenses and/or subscription models for updates and support.
3. Calibration Services: Comprehensive calibration services compliant with international regulations and legal standards for transducers, sound & vibration handheld instruments, and DAQ systems. Services include on-site calibration and calibration certificate issuance.
4. Maintenance, Repair & Support: Preventive maintenance, retrofits, service plans, and fast certified repairs using original parts to extend equipment life and maintain accuracy and reliability.
5. Installation & Start-up Services: Professional installation services to maximize uptime and protect customer investments in HBK measurement equipment.
6. Training & Academy Services: Engineering training courses and seminars covering fatigue, reliability and durability analysis, sound, vibration, test measurement, and other specialized topics for all experience levels.
7. Materials Characterisation & Test Lab Services: Fatigue testing and consultancy services for metals, composites, and additive manufacturing materials including strain-life, stress-life fatigue, fatigue of joints, and fatigue crack growth testing.
