Sisma Lock EVO®

EV165.230

The SISMA LOCK EVO® seismic detector is particularly suitable in applications of industrial plants considered sensitive or RIR (significant accident risk) such as: chemical, nuclear, pharmaceutical, storage of toxic or flammable gases or fluids, inserted in contexts of SEVESO and SIL regulations 3.

The Sisma lock Evo seismic detector is a device capable of measuring telluric type vibrations using a double sensor with MEMS technology. The mechanical signal perceived by the device is converted into an electrical signal, analyzed by means of proprietary algorithms, and used to activate safety devices such as solenoid valves for dangerous fluids, evac alarm systems, sirens, etc. The closing action solenoid valves can take place either directly, through the internal safety relay, or, alternatively, through a control unit (if the sensor is part of a network). The SismalockEvo uses redundant components for greater detection security and allows the sending of earthquake data by means of a signal with the 420mA standard or a signal on the RS485 bus.

The SISMA LOCK EVO® seismic detector is particularly suitable in applications of industrial plants considered sensitive or RIR (significant accident risk) such as: chemical, nuclear, pharmaceutical, storage of toxic or flammable gases or fluids, inserted in contexts of SEVESO and SIL regulations 3.
