ASC 4421MF
Uniaxial, capacitive
Measurement range: ±2 to ±200 g
Noise density: 10 to 680 µg/√Hz
Frequency range (±5 %): DC to 2900 Hz
Rail infrastructure is exposed to continuous mechanical and environmental stresses. From track beds, sleepers and switches to bridges and tunnels, understanding structural health is essential for improving safety, availability and maintenance planning.
ASC’s EQ series accelerometers are designed to capture even the smallest movements. With resolutions below 1 µg, they can detect amplitudes down to one millionth of the earth’s gravitational acceleration – sensitivity that also makes the technology suitable for seismological monitoring of critical structures.
For flexible, ad-hoc measurements, the ASC DiSens EQ takes this capability one step further. The high-precision, ultra-low-noise accelerometer combines high-resolution analog-to-digital conversion with integrated digital data processing and a standard USB interface. Simply connect it to a laptop for plug-and-play configuration, measurement and immediate data processing – without additional data acquisition peripherals.
Whether for continuous structural health monitoring or targeted on-site inspections, high-resolution sensor data can help identify changes early and support smarter, proactive, condition-based maintenance.
