APPLICATIONS
- Earthquake Early Warning systems
- Structural health monitoring (e.g. civil infrastructure, industry, property assets)
- Networked arrays
High-performance, low-noise and compact broadband accelerometers with flexible gain options
The Fortis and Fortimus are strong motion accelerometers, making them ideal for local earthquake early warning and structural health monitoring applications. They all feature flexible gain options so they can perform optimally in a wide range of earthquake monitoring scenarios.
Fortis - analogue instrument
Fortis PH - posthole instrument for prolonged deployment in wet environments
Fortimus - digital accelerometer with Minimus digitiser capabilities in a single compact unit
A strong motion accelerometer with compact design for fast installation in any environment
- User selectable gain options: ±4 g, ±2 g, ±1 g or ±0.5 g, manually on the sensor or remotely when operating with the Minimus digitiser
- Hard anodised aluminium enclosure
- Can be installed easily and rapidly with an M8×75 fixing bolt
- IP68 - protection against effects of prolonged immersion at 3 m depth for 72 hours
- Very low-noise components for high precision and enhanced dynamic range
- Isolated power supply for 10 - 36 V operation
- Acceleration offsets adjustable for <1 mV precision
