Triaxial accelerometer ASC OS-325MF-PG

MEMScapacitivehermetic

Overview
The ASC OS-325MF-PG is a triaxial analog accelerometer based on MEMS capacitive sensor technology. It provides a differential analog voltage output (±2.7 V FSO) and is designed for reliable operation in harsh environments, with integrated electronics for flexible power supply and high shock resistance.

Technology
Sensors of type ASC OS-325MF-PG use MEMS capacitive sensing with integrated signal conditioning. The MF (Medium-Frequency) series offers a broad usable frequency range and stable analog differential output. Key electrical features include a differential output of ±2.7 V FSO and an operating supply voltage from 5 to 40 VDC. Measurement ranges are available from 2 g up to 200 g to match application needs.

Housing
The accelerometer is housed in a hermetically sealed stainless steel enclosure rated to IP68. The device includes an integrated cable that can be supplied to customer-specified lengths and with a choice of connectors to suit installation and wiring requirements.

Applications
The hermetic stainless steel housing and high shock tolerance make the OS-325MF-PG suitable for demanding industrial environments, for example rail transport (bogie stability testing to EN 13749), condition monitoring of construction machinery, vehicle component testing and other vibration or shock measurement tasks.
