Magnetic settling instrument

BLT-CJ1000 typeMagnetic settling instrument

purpose

Suitable for automated measurement of layered settlement of earth and rock dams, as well as settlement of embankments and foundations during excavation and loading processes.

Magnetic settling instrumentThe magnetostrictive sensor used has high resolution, good stability, reliable performance, fast response speed, long working life, linear measurement, absolute output, non-contact measurement, wear resistance, self calibration, and multiple output signal options:RS485、 Standard quantities such as voltage and current, simple and convenient installation, etc.

working principle

The stainless steel measuring rod of the settling instrument is equipped with a magnetostrictive waveguide wire. During measurement, the electronic chamber emits a starting pulse, which is transmitted along the waveguide wire. When the pulse meets the settling magnetic ring, a magnetostrictive effect current pulse is generated. The energy pickup mechanism measures the current pulse and calculates the time difference between the two pulses, which is the absolute position of the settling magnetic ring.

When the soil settles, it drives the settlement magnetic ring placed outside the settlement pipe to move, resulting in relative displacement between the settlement magnetic ring and the measuring rod. The displacement measured by the settlement meter is the settlement of the soil
