Industrial Monitoring Solutions
Seismic Protection & Recording Equipment
Sensonics seismic protection and recording equipment is used for the vibration monitoring of critical infrastructure. As the leading supplier of seismic monitoring and protection systems to the UK nuclear industry, we have solutions to meet with a diverse range of applications providing safe shutdown and recording facilities in the event of an earthquake.
Alarm management and event capture is achieved through our seismic sensors in combination with multichannel recording equipment providing time history, FFT and spectral response analysis. Integrity and robustness are key to our system concept, with protected power supply configurations, custom indication panels, as well as 2 of 3 voted alarm processing suitable for safety critical applications.
