mems accelerometer sensor

Kingmach’s MEMS accelerometer sensors are built for long-term monitoring in harsh environments, where stable zero bias and low noise matter more than spec-sheet extremes. The sensing element, a bulk-micromachined silicon MEMS die, is packaged with temperature compensation to keep scale factor drift minimal across a wide operating range. Common full-scale options span ±2 g to ±200 g, but most structural and geotechnical jobs stay below ±10 g, where resolution of a few micro-g is achievable. Output is either a high-level voltage (0.5–4.5 V ratiometric) or digital via RS-485, making it easy to match with loggers from Campbell Scientific, NI, or bespoke edge devices. What separates a good MEMS sensor from a noisy one isn’t just the MEMS element itself—it’s the surrounding signal conditioning and calibration. Each unit goes through a multi-point calibration on a precision tilt table, not just a “room temperature spot check.” Customers who track long-term stability typically see bias repeatability within 1 mg over 12 months. Inclinometer and vertical arrays are common delivery formats; we bond the sensors into custom aluminum or stainless steel housings with IP68 glanded exits, then pot the assembly to survive submersion or direct burial. For integrators, a plain PCB-mounted version without housing is also available, while full turnkey packages include cellular telemetry and cloud dashboards if needed.
