Cables for electrical connectivity to our instruments are specially designed to obtain low noise signals and more accurate responses from our instruments. Always use HBK cables to interconnec our sensors with the ancillary electronics.
Un accelerometro piezoelettrico con uscita in carica (charge-type) è robusto e progettato specificamente per la misura di vibrazioni ad alte temperature. Il design unico dei nostri sensori di carica offre un'elevata gamma dinamica, stabilità a lungo termine e robustezza.
Gli accelerometri CCLD sono accelerometri piezoelettrici (PE) a carica (noti anche come accelerometri IEPE) con preamplificatori integrati, i cui segnali di uscita sono sotto forma di uscita in tensione a bassa impedenza. La maggior parte degli accelerometri CCLD di HBK è sigillata ermeticamente per proteggerli dalla contaminazione ambientale; essi presentano una bassa suscettibilità alle radiofrequenze e alle radiazioni elettromagnetiche, oltre a un'uscita a bassa impedenza grazie all'amplificatore integrato. Ciò consente l'utilizzo di cavi coassiali economici e lunghi.
Variable capacitance (VC) accelerometers offer exceptional measurement accuracy and robust packaging for reliable operation in harsh environments. These high-quality sensors feature internal MEMS sensing elements and can be used for measuring low-frequency response down to 0 HZ, steady state-linear acceleration as well as low-frequency dynamic events.
HBK Dytran Smart sensors are a new line of sensors with internal capabilities to process the signals inside the sensor and produce a condition indicator customized to the application. The raw data is also available for further analysis.
Measure dynamic and transient forces with HBK vibration force transducers engineered for wide bandwidth, high stiffness, and fast response. Supporting IEPE technologies, they ensure accurate, high-fidelity data capture for impact, modal, and structural testing applications.
Reference Standard Accelerometer designed for measurements in vibration calibration laboratories. The reference accelerometer is typically used for comparison as the "Reference Standard" or by substitution, as the working standard accelerometer.
Non-contact transducers for measuring speed, velocity and displacement by HBK, such as our tachometer probe, designed to indicate the angular (rotary) speed - measured as revolutions per minute (RPM) - of a rotating shaft, like a vehicle engine shaft. In addition, with our Magnetic Transducer, you can excite a test structure using the transducer as a miniature contact‐free electromagnetic vibration exciter to determine the elastic properties of materials.
Our portable vibration calibrator provides accurate acceleration, velocity and displacement calibration of accelerometers, and general instrumentation. The calibrator is handheld, battery-powered and an essential tool for everyday use in changing environments.
Impact hammer and impedance head measurements are often conducted in difficult environments where dust, temperature fluctuations and high humidity frequently pose severe demands on the electrical and mechanical integrity of the instrumentation. All HBK impact hammers have been meticulously designed to meet the expectations for reliability in all such environments.
With the ability to excite from the smallest of structures to various civil engineering structures, HBK has an impact hammer to suit even the most demanding application.
To measure vibration accurately, one must ensure that the useful frequency and dynamic range are not limited by poor accelerometer mounting or poor quality accessories. To achieve good accelerometer measurements, HBK offers a wide variety of highly specialized accessories, including cables, adapters and studs and other types of mounting accessories.
An accelerometer uses a spring‐mass system to generate a force proportional to the vibration responding to a wide range of research and industry test applications. HBK charge and CCLD sensors feature ICP©, DeltaTron™, and TEDS technology for easy setup and consistent measurements. With single-axis and three-axis (triaxial) configurations, the adaptability is extensive.
