PLC Controlled Device
The Geomil Equipment GVT-100 electrical field vane tester is a sophisticated PLC controlled device with a high precision torque sensor. The testing procedure and data acquisition are fully software controlled.
With a nominal torque of 100 Nm, standard vanes of 50 x 100 mm and 75 x 150 mm can be applied allowing for the determination of the undrained shear strength of cohesive soils. The system allows for automatic remoulding to obtain residual shear strength and the remoulded shear strength value.
The measured values are displayed in real-time and simultaneously all data and test variables are logged. A user-friendly spreadsheet is provided to process the data afterwards.
The GVT-100 is designed for the use of standard CPT and casing tubes to drive the vane. The use of standard CPT equipment reduces investment cost for current users.
