Model JF-ACC

A compact wired tri-axial accelerometer (4-20mA)

Rugged construction ‐ IP67 gel filled metal flanged box prevents in‐situ damage or degradation, prolonging monitoring system life

Test function ‐ Electromechanically generates a test force to ensure sensor is working correctly and that installation wiring is operational

Easy mounting - Enclosure incorporates mounting holes for easy fixing to structures, to reduce installation time

The JF‐ACC sensor is a low noise, low drift, 3‐Axis MEMS accelerometer, designed for use in both indoor and harsh outdoor environments. Ideal for systems integrators, universities and organisations with their own maintenance or monitoring teams.

It is rugged, compact and low power, making it suitable for many applications, including structural health monitoring and condition monitoring. Typical applications for the technology include:

Bridge testing to understand vibration response
Longer term structural health monitoring of bridges and buildings
Offshore wind monitoring – understand tower movement and condition
Detection of seismic tremors

The sensor includes a test function, which generates an internal test force to check installation and correct operation.
