New magnetic materials to meet the material in different service environment applications. Phase MAX is A kind of nano-layered transition metal compound with hexagonal lattice structure, the molecular formula is Mn+1AXn, (where M is generally A pre-transition metal, A is mainly A 13-15 main group element, X is carbon or/and nitrogen, and N takes the value of 1-3), 1.
From the bonding characteristics of the MAX phase lattice, the electron cloud overlap between M and X atoms determines the strong ionic bond and covalent bond, while the electron cloud overlap between M and A atoms is weak, which is helpful to reflect the physical and chemical properties of A element. Therefore, if magnetic elements are introduced into the A position of MAX phase, it is expected to be used as functional materials in spintronic devices with unique nano-layered structure, high stability and adjustable anisotropy. However, previous studies have generally believed that post-transition metal elements such as Fe, Co, Ni and Mn with 3D electrons should exist in the M atomic lattice site of MAX phase materials. It is considered to be A great challenge to synthesize magnetic elements to occupy the A site of two-dimensional monatomic layer in MAX phase.

SZ-4SZ-4 magnetoelectric vibration velocity sensor has high resolution and temperature adaptability, and is suitable for seismic exploration in various environments. Mainly installed on the bearing caps of various rotating machinery, such as steam turbines, compressors, fans and pumps. It is an electromagnetic sensor that cuts magnetic lines by a moving coil and outputs a voltage. Therefore, it does not need to supply power during operation, and the explosion-proof vibration speed sensor is an inertial sensor. The vibration signal is converted into an electrical signal by the principle of magnetoelectric induction. . It is mainly composed of magnetic circuit system, inertial mass, spring damping and other parts. A magnet is rigidly fixed to the sensor, and the inertial mass (coil assembly) is suspended by a spring element. jobs.
SZ-4SZ-4 magnetoelectric vibration speed sensor
The SZ-4SZ-4 magnetoelectric vibration speed sensor, vibration sensor and vibration monitor can be used for continuous long-term monitoring and is suitable for measurement of mechanical vibrations such as steam turbines, fans, pumps and coal mills. The working principle is based on a primary component that converts mechanical energy into electrical energy. It is fixed on the bracket by two coils, and a magnetic steel in the middle is connected to the casing through a spring, and the magnetic steel moves in the line. The magnetic lines of force are cut, thus generating an induced electromotive force. The voltage is proportional to the speed of the casing, which is called the vibration speed sensor. The vibration sensor produced by Zhengzhou Hangke has small volume, good sealing and long service life. Due to the double coil structure, it can superimpose the effective signal, and the interference signal attenuation effectively improves the anti-interference ability.
