PCB Introduces Series 3741 MEMS High Sensitivity DC Response Accelerometers for Crash Sled and Aerospace Testing

The Vibration Division of PCB Piezotronics, Inc. (PCB®) introduces Series 3741 New High Sensitivity MEMS DC Accelerometers. Series 3741 offers several models to accommodate various crash sled acceleration profiles, and full scale ranges from 2 to 200 g, up to 2 kHz measurement capability, and sensitivities up to 1 V/g, to accommodate both automotive and aerospace applications.

The Series’ rugged, low-profile design allows for mounting on restricted areas of crash simulation sleds, truck axles and aircraft wing surfaces. Their DC response allows for measurements in both static and dynamic environments. Accelerometers include mechanical over range stops, to prevent damage due to rough handling and transient shock environments. Internal amplification provides high-level signal (±2 V FSO) at low acceleration levels, for low amplitude motion measurements on automotive and aerospace structures. Sensors are also gas damped, and are temperature compensated for stable measurements in varying environments.

This series has been specially designed in response to more stringent automotive safety testing standards, and accompanying occupant safety system requirements, including side-impact protection, child restraints/seat
testing, pedestrian protection, wheelchair integral restraint systems (WIRS), SAE J2249, and rear impact/whiplash. In addition, a variety of model choices allows for applications including motion studies, tilt measurements, ground vibration / flight testing of aircraft and rail car motion measurements.
