Capacitive

SEIKA accelerometers are robust, high‑performance acceleration and vibration sensors built around capacitive spring‑mass technology with integrated electronics. They offer very high overload resistance, excellent long‑term stability, low drift, and strong signal‑to‑noise performance — making them ideal for rigorous use in industrial, structural, seismic, and dynamic measurement tasks. Typical types include rugged models that measure both static and dynamic acceleration with broad frequency response and low non‑linearity.

SEIKA sensor boxes house these accelerometers (and optionally inclinometers) in robust, IP65/IP67 die‑cast aluminium enclosures with built‑in signal conditioning (e.g., 0–5 V or 4–20 mA outputs, temperature compensation and filtering). They deliver ready‑to‑use, calibrated output signals suitable for harsh environments such as construction sites, mining, transport systems, heavy machinery, ships, and automation systems. Configurations range from single‑sensor units to multi‑sensor boxes supporting up to three channels, with options for customised dynamic response and EMC protection.

Advantages:
• Built for extremes: High mechanical overload resistance and rugged housings ensure reliability in demanding conditions.
• Stable, accurate outputs: Integrated electronics and temperature compensation give low drift and clean signals for precise measurement.
• Flexible integration: Sensor boxes provide conditioned analog outputs compatible with standard industrial systems, simplifying installation and data acquisition.
• Modular and scalable: Available in single‑axis, dual‑axis or three‑sensor configurations for complex measurement needs.

These SEIKA accelerometer solutions are widely used where high reliability, durability and measurement fidelity are essential — from structural health monitoring and machine condition analysis to safety‑critical dynamic testing.
