ASC OS-125MF Rugged uniaxial MEMS acceleration sensor

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
