Small charge triaxial accelerometer

16/09/2024

PCB Piezotronics (PCB) has introduced its new Model 357A67 elevated temperature charge triaxial accelerometer. The 357A67 is PCB’s smallest charge output triaxial accelerometer and can withstand temperatures as high as 260°C.

Model 357A67 is small in size at just 19.8 × 10.2 × 11.4 mm and features a high charge output of 3.0 pC/g, high resonant frequency ≥45 kHz and a measurement range of ±1000 g.

Model 357A67 is PCB’s first charge output accelerometer that utilises one multi-conductor cable assembly instead of three individual coaxial cable assemblies, reducing the installation envelope of the sensor/cable pair. This model’s small size 
and integral M3 × 0.5 mm thread allows for ease of mounting within customer assemblies, which can then be tested at temperatures up to 260°C. The rugged titanium shell is hermetically sealed with output through a four-pin ¼-28 pin connector.

Model 357A67 can be used for many test applications involving elevated temperatures and space restrictions. Automotive applications include powertrain development and noise, vibration and harshness (NVH) for vehicle systems. Aerospace and defence applications include environmental stress screening (ESS) and highly accelerated life testing (HALT)/highly accelerated stress screening (HASS) of satellites, as well as vibration testing in thermal vacuum environments and on small objects, small turbines and fuel cells.
