Seismic Switch

Sensonics Seismic Switches offer high integrity protection for critical assets and industrial processes. Providing accurate detection of structural vibration in conjunction with various safe shut down options. As the leading supplier of seismic monitoring and protection systems to the UK nuclear industry we have a range of solutions to meet with most applications.

The SA series of seismic safety switches are triaxial vibration detection devices, suitable for the protection of vulnerable structures from ground borne vibration events. The unit features three high integrity low noise piezoelectric seismometers in combination with alarm circuitry mounted in a robust weatherproof painted steel enclosure. The seismic switch series are seismically qualified to international standards and are suitable for use in a voted protection system configuration.
