Model 1430B

VW vertical multi-point inclinometers are mounted onVW vertical multi-point inclinometers are mounted onwheel assemblies connected by extension tube.The guide wheels on the sensor keep it centered in thegrooved casing that is installed in a vertical borehole thatpasses throu gh a suspected zone of movement andinclinometer casings.
Advantage of VW sensor is that unmanned automatedoperation is possible using data acquisition system, couldbe installed in single axis with gage length of 1-3 meterwhen displacement direction is expected or in biaxis whendisplacement direction is not expected.
The VW vertical multi-point inclinometers are available inboth uniaxial and biaxial versions.When ground behaves, casing is caused a change in theinclination of the sensors in diameter 0 59rnrn casings.
The VW vertical multi-point inclinometers can be connectedup to 60 sensors. The sensor outputs frequency signalwhich changed by lateral movement in the ground.Inside transducer have a lightning protection to prevent thesensor from electrical shock and a temperature device tocompensate for temperature variations in the sensors.
