ASC OS-315LN-PG capacitive MEMS accelerometer

Triaxial low-noise MEMS accelerometer with IP68 stainless-steel housing for railway and structural monitoring


Key features

  • Triaxial measurement (X, Y and Z axes)
  • ±2 g to ±400 g measurement range
  • Very low noise density (7–400 µg/√Hz)
  • Frequency response up to 4.2 kHz
  • Rugged IP68 stainless-steel housing
  • High shock resistance up to 5,000 g

Performance

The ASC OS-315LN-PG is a triaxial capacitive MEMS accelerometer engineered for highly precise measurements of static and dynamic accelerations. With a measurement range of ±2 g to ±400 g, frequency response up to 4.2 kHz (±3 dB), and very low noise density from 7 to 400 µg/√Hz, it ensures outstanding signal quality. Its differential analog output (±4 V FSO) and supply range of 6–40 VDC enable easy integration into measurement systems.

Usage conditions

Built with a hermetically sealed IP68 stainless-steel housing, the OS-315LN-PG is designed for use in harsh environments. It withstands shocks up to 5,000 g and operates reliably in temperatures from −20 °C to +100 °C (depending on cable type). Available with configurable cable lengths, connectors, and optional V4A stainless-steel housing.

Possible applications

  • Railway engineering and bogie stability tests
  • Condition monitoring of vehicles and components
  • Structural health monitoring in civil engineering
  • Long-term outdoor vibration measurement

Advantages of choosing this accelerometer

With triaxial low-noise performance, the ASC OS-315LN-PG delivers maximum precision for demanding applications. It reduces the need for multiple single-axis sensors and guarantees robust, reliable operation under extreme conditions.
