DSD 050 Earthquake Gas Shut-off Unit

• Microprocessor controlled,

• Semiconductor acceleration sensors,

• Non-seismic accelerations filtered,

• Maintenance free,

• Capable of doing self -test,

• 12 V-DC internal battery,

• Direct interface to solenoid gas valves,

• Metallic housing.

The DSD-050 Earthquake Gas Shut-off Unit is a high-tech device which detects seismic acceleration occurring during an earthquake and generates control signals to shutdown the solenoid valve.
DSD-050 is based on very sensitive silicon micromachined sensors. It is lightweight, small, maintenance free and capable of performing self-test.
The seismic properties of the device are conformal to ANSI Z.21-70(1981), ASCE 25-97 and TS-12884 (2002) standards.
