Learn MoreThree-Axis Equal-Diameter Coil
Product Descriptions
The Three-Axis Equal-Diameter Coil, which is a type of three-axis Helmholtz coil exclusively developed by our company, features the nominal diameter coil, the same number of winding turns, and the same specification of wires per axis.
This winding construction allows the Three-Axis Equal-Diameter Coil to have the same resistance, inductance, homogeneity, and B/I coefficient per axis; The coil per axis is fixed to each other in the embedded form, of which this mechanical structure makes the coil to feature a small size and the greater accessibility to the working gap; the whole former is made of non-magnetic PMMA material, which is applied for the study of low and weak magnetic field, and which is very suitable for the shielding room and the magnetic shield. The highest magnetic field of a three-axis equal diameter coil can be designed to be from 0 to 5 Gs. -

Learn MoreMagnetic-Moment-Free Coil
Product Descriptions
The Magnetic-Moment-Free Coil is composed of several pairs of coils, which are installed in a certain geometric structure, and of which the certain number of coil’s turns and a certain current direction make the magnetic field outside the Magnetic-Moment-Free Coil attenuate rapidly and make the magnetic moment of the Magnetic-Moment-Free Coil be zero. One of outstanding advantages of the moment-free coil is that it does not produce magnetic interference to the environment outside a certain distance from the Magnetic-Moment-Free coil during operation, which means that it is very significant for the simultaneous operation of multiple systems; In addition, the moment-free coil does not magnetize the adjacent magnetic substance, therefore, it does not bring extra errors to the moment-free coil in this respect. -
Learn MoreHigh Homogeneity coil
Product Descriptions
High Homogeneity coil, which is composed of multi-ring coils arranged along the axial direction, includes the common coils such as Barker Coil, Braunbek Coil, Maxwell Coil, Rubens Coil, and Magnetic-Moment-Free coil. Compared with the Helmholtz coil, the combined coil features the better magnetic field homogeneity under the same diameter, the higher homogeneity and larger homogeneity volume in the effective space, and is suitable for the high-precision and large-range magnetic field needs. This design can meet any parameter customization requirements.

HEA Series Power Amplifiers
HEA series power amplifiers are specially designed for the use of exciter, which can provide a stable and adjustable excitation current for the exciter.Under the action of the excitation current, the exciter generates an excitation force on the tested component that corresponds to the excitation current, and the magnitude and phase of this force are only related to the excitation current and the characteristics of the exciter itself, but which is independent of the tested component.<br/> HEA series linear power amplifiers has below advantages: stable performance, strong protection function, easy to operation, no impulse during startup, no pollution to the environment, safe and reliable use. In addition, HEA series linear power amplifiers have good adaptability, which is suitable for the impedance of its basic matching load. It is widely used in excitation of inductive loads such as electromagnets and Helmholtz coils.
