Performance higlights

The ASC OS-125MF-PG is a high-performance, uniaxial MEMS capacitive accelerometer engineered for medium-frequency applications in harsh industrial environments. Designed with gas-damped MEMS elements and a rugged stainless-steel housing, this sensor delivers low noise, stable offset, and excellent scale factor repeatability.

It features a differential analog voltage output of ±2.7 V and operates on a flexible 5 to 40 VDC supply. Thanks to its robust design and IP68 hermetically sealed enclosure, it is highly resistant to dust, moisture, and mechanical impact – ideal for railway bogie monitoring, construction machinery, and structural health monitoring in tough outdoor settings.cles and their components in the construction sector.

Applications

Railway engineering
Condition monitoring
Structural health monitoring
Heavy-duty environments

Operating conditions

The OS-125MF-PG performs reliably in ambient temperatures from -20 °C to +70 °C, with an optional high-temperature variant up to +100 °C. Its hermetically sealed stainless steel housing ensures full IP68 protection, while the compact form factor (68 g) and screw or adhesive mounting options allow for easy integration into existing measurement setups.

The standard 6-meter PUR cable is highly flexible and optionally available in FEP for increased chemical resistance. Cable length and connector configurations are fully customizable.

Advantage of this sensor

Shock-resistant up to 6,000 g – robust for extreme vibration environments
Gas-damped MEMS element – accurate DC and low-frequency response
Wide power supply – compatible with many DAQ systems (5–40 VDC)
Low noise floor – ideal for precision vibration measurement
Rugged IP68 stainless steel housing – maintenance-free in wet or dusty locations
Customizable output cable & connector – easy to integrate into any system
