Accelerometers Linear Static & Dynamic
Product Announcement from Rieker, Inc.
Rieker accelerometers are small capacitive spring mass-based accelerometers with integrated electronics that do not require external amplifiers. The B Series - B1, B2, B3 – are static accelerometers for acceleration measurements in the frequency ranges from 0Hz to 550Hz. The BDK Series are dynamic accelerometers for measurements in the frequency ranges from 1Hz to 1.5kHz. The units are available with analog DC output, digital pulse-width, or frequency- modulated outputs and have a very high resistance to extreme acceleration overloads and shocks (up to 10,000g). Light weight and compact in size (less than 24mm or .93"), these accelerometers can be configured to measure acceleration due to gravity (inclination) or radial acceleration (centrifugal force) in single, dual, or tri axial packages.
These accelerometers are characterized by very high overload resistance, linear frequency response with minimal resonance peaking (resonant peaks are minimised by means of a special gas-dynamic damping in the primary transformer), low distortion factor, low-impedance signal output, high signal to noise ratio, very low cross-axis interference, very low output-signal hysteresis, hermetically sealed, and very short settling time. Because of the low power consumption, these sensors have very low drift and long-term stability. Galvanic isolation, choice of housing style, and long connection leads are options. Typical applications are for measuring or determining machine vibration, vehicle acceleration, seismic activity, inclination, and safety levels. These can be also be used for process control, stress control, shock control, crash testing, vibration analyzing, and dynamic rate determination.
