JL-2000 magnetostrictive static level Introduction: The main components of the device consist of a measuring rod, an electronic chamber, and a non-contact magnetic levitation ball mounted on the measuring rod. The measuring rod is equipped with magnetostrictive wires (waveguide wires) and is made of non-magnetic stainless steel tubes, which reliably protect the waveguide wires. During operation, a starting pulse is generated by the circuit. When the starting pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire. When this magnetic field meets the permanent magnetic field in the floating ball, a magnetostrictive effect is generated, causing the waveguide wire to twist. This twist is sensed by the electronic pickup mechanism and converted into corresponding current pulses. The measurement circuit calculates the time difference between the two pulses to accurately measure the measured liquid level value. The sensor output is a digital interface, and each instrument has a writable address. All sensors only need to use one 4-core cable to transmit the measured values to the data acquisition device for output or display of readings. Each static leveling system must be equipped with a reference measuring point. When there is settlement or uplift relative to the reference point at the measuring point, the liquid level of the storage tank at the measuring point changes accordingly. The change in liquid level drives the internal float to change and be sensed by the internal sensitive devices, ultimately outputting through cables. The magnetostrictive static leveling system is a precision instrument used to measure the relative elevation changes between two or more points. Mainly used for monitoring vertical displacement of dams, nuclear power plants, high-rise buildings, mines, landslides, bridges, etc. The static leveling system is generally installed on a measuring pier of equal height to the measured object or on the contour line of the measured object's wall, and the supporting data acquisition instrument can achieve automated observation. The JL-2000 magnetostrictive static level includes a magnetic float level sensor, a liquid storage tank, an installation bracket, etc. The entire system is composed of two or more devices connected together by a Φ 14mm liquid pipe and a Φ 6mm air pipe, and the settlement is converted by the change of the float. The vent pipe is used to connect liquids, and its function is to maintain the same air pressure inside all storage tanks in the system to keep the liquid level consistent. Technical parameters: Range: 200mm Nonlinear error:<± 0.05% F.S Repetitive error:<± 0.002% F.S Resolution: 5 μ m Update time: 2ms Delay:<0.002% F.S Temperature coefficient:<0.007% F.S./℃ Working temperature: -20 ℃~+85 ℃
