It primarily outputs ground accelteration and velocity. It features a unique mass locking system which reduces the possibility of damage to the sensor pivots and springs. It is housed in a titanium sphere and depth-rated to 3000 m. It features 360 s velocity feedback and an operating frequency of 50 Hz."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1589" ; skos:note "accepted"@en ; skos:prefLabel "Guralp Systems CMG-1T ocean bottom seismometer"@en ; skos:related , . skos:related .
