Magnet Settlement Probe
The model MAS-CJY series magnet settlement probe is used in conjunction with settlement tubes and settlement magnetic rings to measure layered settlement or uplift. The settling magnetic ring is made of injection molding,with magnetic material placed inside to form a magnetic ring, and a spring leaf installed outside. The magnetic ring is placed on the outside of the tube.This instrument has a simple structure and is easy to operate. It can be used during the construction period or for long-term safety monitoring of the settlement in soft soil foundation reinforcement, earth-rock dams, foundation pit excavation, backfill and embankment projects.
Overview
The measurement of settlement involves two main components: one is the underground embedded section, consisting of settlement tubes, base plates, and settlement magnetic rings; the other is the surface receiving instrument - a steel ruler settlement gauge, composed of components such as the measuring head, measurement cable, receiving system, and winding reel.
Measuring Head Section: Made of stainless steel, it contains an internally installed magnetic field sensor. When exposed to an external magnetic field, it activates the receiving system. Conversely, when the external magnetic field is absent, the receiving system automatically shuts down.
Measurement Flat Tape Section: The tape is a combination of a steel ruler and a conductor using plastic technology. This design prevents rusting of the flat tape and simplifies the operation, making readings more convenient and accurate. One end of the steel ruler cable connects to the measuring head, while the other end connects to the receiving system.
Receiving System: Comprising a buzzer and peak indicator, the buzzer emits a continuous buzzing sound, and the peak indicator is displayed by the pointer of a voltmeter. Both functions can be selected using a toggle switch. Regardless of the type of receiving system used, the measurement accuracy remains consistent.
Tape Reel Section: Composed of a circular disk and a bracket, it accommodates the receiving system and batteries within the core cavity of the flat tape. The flat tape is wound externally around the cavity.
