Hello

Anyone here know if any of the old 60's sensors, Long or short
period, existing at the *World-Wide Standard Seismographic Network (WWSSN) *can
be adapted to work today with new data acquisition systems? They were
Benioff sensors with variable reluctance for the short-period instruments
and Ewing Press sensors for the long period.

Regards

Rui
