Seismic sensor for solenoid valves M90W

Description

Seismic sensor for solenoid valves Madas M90W

Device that, combined with a gas safety solenoid valve, controls its closure in the event of:

• seismic event (with analysis over time and based on the frequency of the accelerations)
• remote control (e.g. gas detector, emergency closure)

The device has a relay alarm output that can be used for remote signals and to disconnect the power supply, thus eliminating any sources of ignition or explosion. The sensor can be connected electrically to normally closed/open solenoid valves with manual reset (also already installed).

The seismic sensor has been tested in accordance with: ASCE 25-06 (USA) - TS12884 (Turkey).
