Royal Observatory of Belgium Gravitational balance
Michel van Ruymbeke, Sébastien Naslin, Ping Zhu +2
An astatized symmetrical vertical pendulum is monitoring torque Γ(M) resulting of gravitational attractions exerted by two external masses M moving up down. Local gravity field g p…
Spring gravimeter calibration experiment with an inertial acceleration platform
Ping Zhu, Michel van Ruymbeke, Jean-Phillippe Noel
This experiment tested an automatically calibrate the relatively gravimeter with an absolute inertial force. The whole calibration system was controlled by microprocessor and low f…
Hydrological and tectonic strain forces measured from a karstic cave using extensometers
Ping Zhu, Michel van Ruymbeke, Yves Quinif +2
In order to monitor the hydrological strain forces of the karst micro fissure networks and local fault activities, six capacitive extensometers were installed inside a karstic cave…
