Triaxial accelerometers

12/08/2025

PCB Piezotronics (PCB) has announced the launch of its new Model 3743G differential variable-capacitance triaxial accelerometer. This innovative sensor is designed to meet the demanding requirements of the automotive and aerospace industries with superior performance and versatility.

The 3743G features variable-capacitance microelectromechanical systems (MEMS) technology for stable and accurate measurement. Featuring a wide input voltage range from 5 VDC to 32 VDC, these sensors excel in applications requiring low-frequency and long-duration event measurement, due to their direct current (DC) frequency response.

The 3743G combines the benefits of differential output (common mode noise rejection) with a screw mount package for easier installation. If a bridge signal conditioner is not available, the 3743G can be used in single-ended mode with any DC voltage supply, which will provide half of the sensitivity of differential mode.

Model 3743G features precise measurement with excellent linearity and very low temperature error, a differential output providing excellent common mode noise rejection, dual-mode operation offering the flexibility of both differential and single-ended modes, catering to a variety of situational needs, and a rugged design capable of withstanding shocks of up to 5000 g, ensuring durability in demanding applications.

The model comes in two options: 3743G11 and 3743G12. The 3743G11 has a hermetic stainless steel package with integral M8x1 eight-pin connector. The 3743G12 utilises the same stainless steel package with an IP67 connection to its integral cable.
Suggested applications include aircraft flight and flutter testing, automotive ride quality and road load data acquisition (RLDA) and vibration measurement in space launch vehicles.
