ASC CS-1511LN / CS-1611LN MEMS Capacitive accelerometer with 4–20 mA output

Low-noise MEMS acceleration sensor with analog current output for structural and industrial vibration monitoring


Key features

  • Standard 4–20 mA current output
  • Low broadband noise: <0.65 μA
  • Excellent EMC resistance
  • Measuring range ±2 g to ±50 g
  • DC response, gas-damped MEMS
  • IP67/IP68 housing (aluminum or stainless steel)

Performance highlights

The ASC CS-1511LN and CS-1611LN are MEMS capacitive accelerometers with a standardized 4–20 mA current output, designed for high-reliability applications in harsh industrial environments. Their excellent EMC immunity, low noise, and wide frequency range from DC to 2,000 Hz make them ideal for long-distance signal transmission in condition monitoring systems.

The output is compatible with most industrial control and SCADA systems and ensures signal stability even over cable runs >100 meters.

Usage conditions

The CS-1511LN is a biaxial version; the CS-1611LN is available in triaxial configuration. Both sensors come in a compact, sealed aluminum housing with IP67 protection as standard. Stainless steel versions and IP68-rated versions are available for applications in tunnels, bridges, or offshore environments. All sensors include integrated cabling, with options for customized lengths, shielding, and connectors. The current loop design eliminates signal loss across long cable routes, making this sensor ideal for structural and infrastructure monitoring.

Typical applications

  • Structural health monitoring (SHM) of bridges, tunnels, buildings
  • Vibration monitoring in railway and energy infrastructure
  • Long-distance industrial condition monitoring
  • Monitoring under high EMC exposure
  • Environments requiring robust analog current output

Advantages of this sensor

The ASC CS-series offers a reliable alternative to voltage-based sensors for projects with long cable distances or strong electromagnetic interference. MEMS capacitive technology ensures high stability, low drift, and a compact form factor suitable for fixed installations. Combined with a wide operating temperature range and stable output, these sensors are built for durability.
