Teledyne Geotech S-13 Short Period Sensor
Teledyne Geotech S-13 Short Period Sensor
This passive 1-Hz sensor is seldom used because there are not many in the EPIC fleet and they have essentially been replaced by the CMG-40T-1Hz feedback seismometers. Information about S-13's from the old website can be found here.
The S-13's are heavy and awkward. The three components are separate units (about 20lbs each). They have strong magnets (passive seismometers), so they require about 12-inch spacing between each component.
