Mud Flow Detection

Description:

TMP was designed to operate with seismometers SERCEL L -10B model ( 4.5 Hz ) or compatible. The operating principle of this sensor is based on the Faraday induction law , which predicts that a change of the magnetic flux through a conductor wire will generate a voltage. The sensor has a magnet which functions as a mass spring system is surrounded by a coil on which the voltages that are analogous to the movement of the ground, produced by increasing water and debris called mudflow is induced. A simple algorithm detects the envelope of these variations, and previous experience thresholds are set to detect moving mudflows by a channel of a river.

The TMP digitizes voltage variations and applied the detection algorithm and converts data, which are sent by telemetry to the base processing and / or monitoring for interpretation and / or alarm. The detection methodology mudflows is of great importance for the monitoring and surveillance of river basins , as it can be an early warning tool for communities living near the runway threatened by mudflows rivers, created by climatic, volcanic or tectonic phenomena .
