Real-time Displacement Monitoring

                   with Digital Wire Extensometer and Wireless Transmitter

Set up a warning system and/or repeater station in a suitable location within the transmission distance to receive signals from multiple transmitters. Besides the signal of displacement, it can receive other signals of crack, groundwater, and soil saturation status, etc.

※    Detects the signal of displacement based on the amount and rate to identify different levels of landslide event and provides an alarm signal.

※ Provides the signal periodically so as to ensure stable operation and also indicate the power status.

※    Low power RF with transmission ranging up to 2km (with optional module) reduces the equipment and installation cost and power requirement.

※ Extended cable up to a maximum of 400cm can reflect the landslide status.
　
Debris flow monitoring

The transmitter is set in the stream.

It monitors the displacement of anchors or big rock in the stream bed and will provide an alarm signal based on the amount and rate of displacement transmitted from the trigger pulse.
 Landslide Monitoring

The transmitter is set in the upper and/or lower slope.

It monitors the potential and status of landslide, and will provide the signal per 1mm displacement and will trigger alarm according to the velocity change in the shallow ground.
Rock-fall Warning

The transmitter is set on the Rock-Fall Catch Fencing.

It provides the signal per 1mm displacement. According to the amount of the rock-fall, the station can warn the roadway users in time.
　 　 　

Debris flow warning

The transmitter is set in a slit dam or a debris dam.

It provides the signal in the process of flow squeezing action and will trigger alarm based on the amount and rate of displacement transmitted from the trigger pulse. When the intensity of debris flow increases, it may make the cable broken or even departed from the snap.
 Roadway slope Monitoring

The transmitter is set in the roadway embankment.

It monitors the potential and status at the ground surface across the head scarp of the lower slide and will provide the signal per 1mm displacement, and trigger alarm according to the velocity change. The cable can extend from one side of the failure zone to the other side through a flexible pipe buried in the trench.

Settlement monitoring

The transmitter is set on a ground surface.

Anchors are mounted at the bottom of a borehole. The transmitter measures the amount of displacement between the anchors and the transducer base. It will also provide an alarm signal when the trigger pulse exceeds a preset level.
