Uniaxial accelerometer ASC ECO CS-1311

capacitiveMEMScurrent output

Product overview
The ASC ECO CS-1311 is a uniaxial accelerometer based on MEMS capacitive sensor technology. It delivers a single-ended analog current output (4-20 mA) and is built for industrial monitoring tasks requiring long cable runs and high electromagnetic compatibility. The sensor family provides low broadband noise, high shock resistance and flexible power supply options in an IP67 aluminium housing with integrated cable and configurable connectors.

Key features

• Sensor technology: MEMS capacitive
• Sensing direction: Uniaxial
• Output signal: 4-20 mA (single-ended)
• Power supply: 8–25 VDC
• Available measurement ranges: ±2 g, ±4 g, ±8 g, ±10 g, ±20 g, ±40 g

Performance and usage
Broadband noise is <4.5 μA, enabling reliable, loss-free signal transmission over very long cable lengths (>100 m) and strong EMC immunity. The models offer wide frequency response and shock resistance up to 10,000 g, making them suitable for structural health monitoring, infrastructure monitoring (rail, bridges) and other civil engineering vibration measurements.

Additional notes
Frequency specifications vary in available documentation: the series is listed as DC to 2.4 kHz (±3 dB) on product content, while page metadata also shows DC to 630 Hz (±5%). Both values are reported in the product information.

Housing and environmental
Lightweight aluminium housing rated IP67 with integrated cable. Connector type and cable length are configurable. Operating temperature range: -20 °C to +80 °C.

Applications

• Infrastructure monitoring (e.g. rail transport)
• Bridge structural analysis
