Overview

The ASC 5511 LN / 5515 LN is a triaxial accelerometer based on capacitive MEMS technology, allowing, thanks to its high resolution and low noise sensitivity, the precise and reliable measurement of small variations in acceleration over measurement ranges from ±2g to ±400g on 3 x, y, z axes simultaneously.

The ASC 5511 LN / 5515 LN acceleration sensor has a frequency range between 100 and 1000 Hz depending on the model and is therefore suitable for the study of low and medium frequency dynamic behaviour. The good accuracy (less than 1% non-linearity) is achieved by compensating the calibration over a wide temperature range.

Operation

Signal output and installation

The amplified signal output of the ASC 5511 LN / 5515 LN (±4VDC) is independent of the supply voltage (8 to 30 VDC). With an IP67-rated housing made of hardened aluminium (20 g) or steel (40 g), an operating temperature range of -40 to +100°C, and a shock resistance of up to 4000g, the ASC 5511 LN / 5515 LN sensor is suitable for use in harsh industrial environments. Mounting is by screwing or gluing.

Wiring

The standard cable (30 gram/meter; PUR; AWG 30; Diameter: 4.4mm) is available in 8 or 12 wires. The standard length (6m) can be adjusted as required (limit of about 30m). A LEMO, Jaeger, BNC or other connector can be added as an option. A trident arrangement of the wires is also available as an option to simplify the connection to the acquisition system.
