ASC OS-115LN Compact MEMS Accelerometer

Uniaxial low-noise MEMS accelerometer with IP68 stainless-steel housing and detachable connector cable 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
  • Robust IP68 stainless-steel housing
  • Detachable connector cable
  • Shock resistance up to 5,000 g

Performance 

The ASC OS-115LN is a uniaxial capacitive MEMS accelerometer designed for high-precision static and dynamic measurements. With a wide measurement range of ±2 g to ±400 g and a frequency response up to 4.2 kHz (±3 dB), it ensures reliable performance in demanding applications. Its low-noise design (7–400 µg/√Hz) enables detection of the smallest frequencies and amplitudes. The accelerometer delivers a differential analog output (±4 V FSO) and operates with a flexible supply voltage of 6–40 VDC.

Usage conditions

Featuring a hermetically sealed stainless-steel IP68 housing, the OS-115LN provides long-term stability in harsh environments. It withstands shocks up to 5,000 g and operates within a temperature range from −20 °C to +100 °C (depending on cable type). The detachable connector cable offers easy replacement and system flexibility.

Possible applications

  • Railway engineering and bogie stability testing
  • Condition monitoring of vehicles and machinery
  • Structural monitoring in construction and civil engineering
  • Long-term vibration monitoring in outdoor environments

Advantages of choosing this product

With its combination of low-noise design, detachable cable, and rugged IP68 housing, the ASC OS-115LN offers high accuracy, reliability, and easy maintainability. It is the ideal choice for engineers working on demanding railway, industrial, and structural projects.
