EPIC Intermediate-Period Sensors:
Guralp CMG3-ESP
Guralp CMG40T
Nanometrics Trillium40
Features:
The low-period corner is 30 seconds for the 3 Guralps and is 40 seconds for the Nanometrics sensor. All are 3-component feedback sensors. The CMG40T and Trillium40 masses do not lock. One should still ship and handle them with care so as not to damage them. The CMG3-ESP has masses that require manual locking and unlocking.
