Our range of vibration transducers includes accelerometers, force transducers, impedance heads, impact hammers, tachometer probes, vibration calibrators, cables and accessories.
Standard sensors often reach their limits when faced with today’s engineering challenges. With HBK, you can design and produce sensors that combine precision, performance, and seamless integration—engineered to fit perfectly into your application.
A transducer is a device that converts energy (electrical signals is a form of energy) from one form to another so that the desired characteristics of the input energy can be read at the output signal.
Transducers are a vital first link in your measurement chain.
Transducer sensitivity can be stated in electrical quantity/physical parameter (for example, Picocoulomb/m/s2) or physical parameter/electrical quantity (such as Pascals/Volt).
The terms transducer and sensor are in many cases used interchangeably.
Both a sensor and a transducer can respond to changes in a physical phenomenon (like temperature or pressure) and provide a signal that can be measured using appropriate instrumentation. However, they can be very different devices with notable differences in characteristics.
There are many transducers types and equally many measurement applications.
Whether you measure electrical signals, high-frequency acceleration (HFA), or sound waves, our transducers stand on the front line and provide you with the full scale of raw data needed to make informed decisions. As an example, our sensors and airborne amplifiers are being used to provide critical flight data for a rocket's onboard telemetry. In situations like these, it is absolutely vital that the data is trustworthy.
The measurement applications range from the development of quieter, safer cars, to ensure that an aircraft and its engines are totally reliable and environmentally friendly and that household appliances have low levels of noise and vibration.
The HBK types range from industry-leading measurement microphones, and hydrophones, to sound sources (or loudspeakers and amplifiers)designed for acoustic measurements, to force sensors, impact hammers, and our extensive range of accelerometers for vibration measurements.
HBK Test and Measurement market-leading strain, force, load and pressure sensor technology provide accuracy in a wide range of measurement applications.
HBK has invented many of the technologies used in most today’s accelerometers and microphones. It is our firm conviction that technology has no limits. If we can imagine it, we can develop it.
In production, every HBK product is thoroughly tested to ensure that its performance is within the specified parameters. All components, whether from sub-suppliers or manufactured, are subjected to rigorous inspection. The inspection takes the form of physical and dimensional control systems to ensure conformity to specifications and quality, as reflected in our status as an ISO 9001 and EN 9100 certified company.
With ultrasound, components are inspected and then cleaned in a demineralized water and soap solution. The parts are then dried using compressed air and placed in an oven to remove any traces of humidity. A unique process is then applied to clean the electronic components. On average, we conduct between five and ten separate test procedures together with individual calibration and validation before shipment.
HBK products are made with the utmost care and tested in extremely harsh environments. You can follow the process in this video showing the making of Type 4966 Free-Field Microphone:
We perform an individual calibration before shipping. Our unique status as the primary Danish standards lab reduces our traceability steps and uncertainty in measurement sensitivity.
The information we gather when testing and calibrating is detailed in our product datasheets, providing information on device sensitivity to external inputs together with any additional specifications.
Calibration is performed in our own laboratory using a technique based on FFT analysis.
This provides the needed resolution to detect certain types of problems that are hard to identify in other systems.
