Case Isolated Triaxial ICP Accelerometer available from PCB Piezotronics with expanded frequency range up to 10,000 HZ
PCB Piezotronics has released two upgraded triaxial ICP accelerometers with an increased frequency range that extends upper limits to 10,000 Hz at 5% deviation. Models 354B04 and 354B05 are case isolated to help ensure measurement quality in the presence of electrical noise and both sensors are TEDS IEEE 1451.4 enabled for easy tracking and record keeping.
Models 354B04 and 354B05 were designed with durable and rugged titanium housings to maintain electrical isolation even if the housing is scratched or damaged during normal use. The hermetically sealed housings are low outgassing by design for use in vacuum environments such as spacecraft testing. Both models have an operating temperature range from -65 to +200° F (-54 to +93° C) and a shock overload limit of ±5,000 g pk.
“Case isolation helps to ensure measurement fidelity in the presence of electrical noise that is typically encountered during electric vehicle vibration testing,” said Bob Metz, director of PCB’s aerospace and defence division. “Models 354B04 and 354B05 are also ideal for flight and ground vibration testing applications for new eVTOL aircraft, environmental stress screening (ESS), modal analysis and structural testing.”
The case isolated design eliminates the need for special isolation bases, coatings and insulated mounting screws. The thru-hole mounting configuration allows these accelerometers to be rotated 360 degrees prior to tightening the screw, allowing for easy installation. Built-in ICP microelectronics provide a low noise, low impedance output signal capable of transmission over hundreds of feet of cable length. Any ICP signal conditioner or data acquisition system that incorporates an ICP constant current power supply can be used to power the accelerometers.
