A new electromagnetic strainmeter for the monitoring of ground-field deformations.</Title> <Authors>Sgrigna, Vittorio; Conti, Livio; Zilpimiani, David</Authors> <Issue Date>2009-06</Issue Date> <Is part of>Laboratori Nazionali del Gran Sasso, INFN, Annual Report 2008</Is part of> <Pages>187-193</Pages> <Abstract>An original differential electromagnetic strainmeter has been made for wide base-length and high-resolution ground-based continuous measurements of deformation processes. The equipment consists of a couple of central and peripheral units located at a sight distance relatively to each other. Each unit includes an antenna, an electronic package, and the power supply system. The central Unit is linked to a computer through an analog-to-digital converter. The equipment has been designed, built, assembled and calibrated in the ESPERIA Laboratory of the Department of Physics of the Roma Tre University. It can process, transfer and store data to a mass memory unit.</Abstract> 2009-05-31T22:00:00Z
