Both accelerometers include a ThetaShear® sensing element, which enhances performance and provides low susceptibility to temperature transients and base bending. The miniature titanium construction and hermetically sealed (glass) connector are specifically constructed to withstand operation in rough environments and provide resistance to humidity and aggressive gases.
Characteristics
The accelerometers work on a low-impedance output enabling the use of inexpensive long cables and connection to a DeltaTron power supply (ICP® compatible). The built-in low-noise preamplifier gives 110 dB dynamic range, enabling measurements of both low- and high-level acceleration. Brüel & Kjær has given special attention in assuring the stability, reliability and long-term operational life of the transducer, including (but not limited to):
Calibration
The transducers are individually calibrated using state-of-the-art random FFT (Fast Fourier Transform) technology. providing an 1600-point, high-resolution calibration (magnitude and phase). This gives a unique characterisation and secures the integrity of the vibration measurement. Field checking and system calibration are both made simple by using Brüel & Kjær’s hand-held vibration Calibration Exciter Type 4294.
