ASC OS-115LN-PG MEMS Capacitive accelerometer

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


Key features

  • Uniaxial measurement (X-axis)
  • ±2 g to ±400 g measurement range
  • Very low noise density (7–400 µg/√Hz)
  • Frequency response up to 4.2 kHz
  • Hermetically sealed stainless-steel IP68 housing
  • Shock resistance up to 5,000 g

Performance

The ASC OS-115LN-PG is a uniaxial capacitive MEMS accelerometer engineered for high-precision static and dynamic measurements. With a measurement range of ±2 g to ±400 g and a frequency response up to 4.2 kHz (±3 dB), it ensures excellent performance across applications. The sensor’s very low noise density (7–400 µg/√Hz) makes it suitable for demanding vibration analysis and condition monitoring. Its differential analog output (±4 V FSO) and wide supply voltage range (6–40 VDC) allow for flexible system integration.

Usage conditions

Built with a robust stainless-steel IP68 housing, the OS-115LN-PG operates reliably in harsh environments. It withstands shocks up to 5,000 g and performs in temperatures ranging from −20 °C to +100 °C (depending on cable type). Optional V4A stainless-steel housing and customized connectors or cable lengths are available for specific application needs.

Possible applications

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

Advantages of choosing this product

The ASC OS-115LN-PG combines uniaxial low-noise performance with rugged durability. It delivers high-resolution results in demanding applications, while its hermetically sealed design ensures long-term stability and minimal maintenance in extreme environments.
