ASC OS-125MF Rugged uniaxial MEMS acceleration sensor for offshore and industrial vibration monitoring

Rugged uniaxial MEMS sensor with low noise and high reliability for offshore, railway and structural vibration monitoring.


Key features

  • Capacitive MEMS technology with analog voltage output
  • Uniaxial configuration for directional acceleration measurement
  • Measurement range: ±2 g to ±200 g
  • Medium frequency bandwidth up to 1,800 Hz
  • Stainless steel housing, hermetically sealed (IP68)
  • High shock resistance: up to 6,000 g
  • Differential mode for improved S/N ratio
  • Detachable rugged cable (1 meter standard)

Performance

Precision for demanding environments. The ASC OS-125MF is a uniaxial MEMS capacitive accelerometer with amplified analog output, designed for medium-frequency vibration analysis. With low noise density and excellent stability, it ensures accurate performance across a wide temperature range.

This sensor features a stainless-steel, hermetically sealed IP68 housing designed for immersion in saltwater and harsh industrial environments. Optional cables and connectors offer even more flexibility in integration.

Applications

  • Vibration monitoring in wind turbines and offshore platforms
  • Structural health monitoring of civil infrastructure
  • Railway bogie testing and brake analysis
  • Ride quality and comfort testing in vehicles
  • Modal analysis and endurance testing
  • Marine and shipboard vibration diagnostics

Advantages

With a robust housing, differential signal output, and flexible power supply range (5–40 VDC), the OS-125MF is built for professionals who demand precision and reliability — even under extreme environmental conditions.

Available options

  • Custom cable lengths and connector types
  • TEDS module support
  • Extended temperature range (-55 °C to +125 °C) available
