New Series of Miniature Triaxial Accelerometers A new series of triaxial accelerometers is now available in a variety of sizes and sensitivities from PCB Piezotronics. These sensors will simultaneously measure vibration or shock in three orthogonal directions, having three independent sensing elements oriented for response to motion along the x, y and z axes. A wide choice of 16 different models are offered to suit a variety of applications including engine and NVH studies, modal analysis, road response tests, vehicle, flight and packaging testing. Designed to be particularly small in size and with low profiles, the triaxial accelerometers suit testing situations where high frequency response, minimised mass loading and space restrictions apply. The sensors are constructed in precision-machined metallic housings and have built-in microelectronic signal conditioning circuitry to provide clean, low-impedance voltage output signals (ICP) capable of being transmitted over long cable lengths. Measuring ranges from ±5 to ±500g peak are available, with overload protection up to ±5000g peak and a frequency range of 0.4 to 5000 Hz., dependent on chosen model. They will operate over a temperature range of -53 to 121 Deg.C and have a transverse sensitivity of less than 5%. Multi-channel signal conditioners are also available for powering the accelerometers and interfacing their measurement signals to readout, recording and analysis instrumentation. ________________________________________________________ January 2001
