Circular Helmholtz Coils
-
Helmholtz-Coils are especially designed to generate precisely defined magnetic fields from DC to the upper end of the audio frequency range and beyond. The generated fields are in a strongly linear relation to the coil current. The field- strength can be calculated exactly by analytical (or numerical) methods, based on the coils' geometry, the number of turns and the coil current.

Standard Helmholtz Coils
-
Helmholtz Coils are ideal for the measurement of Rare Earth (Samarium Cobalt, Neodymium) and Hard Ferrite permanent magnet materials (materials which exhibit a relative straight line demagnetization). Our standard Helmholtz Coils are for use with fluxmeters. The Helmholtz Coil measures the magnet sample as a single magnetic moment provided that the longest dimension of the magnet sample is less than one-third (1/3) the diameter of the coil system. By definition, the magnetic moment per unit volume is the intrinsic magnetization of the sample. With our calibrated Helmholtz Coil and Integrated Fluxmeter – and given the volume of the permanent magnet sample – the intrinsic open circuit operating B (Bdi) can be measured.

Magnet Testing
Helmholtz Coils
-
A coil arrangement consisting of two coils with the same radius or edge length is called a Helmholtz coil. At the correct distance, these coils are arranged in parallel on the same axis and current flows through them in the same direction. Their magnetic field is then characterized by a large homogeneous area in the center of the coil, which is freely accessible for experiments and measurement tasks. Helmholtz coils can have a circular or square geometric shape.

In the measurement of magnetic fields by means of Hall probes or measuring coils it is necessary to calibrate the instruments in a known magnetic field. Our standard field coil according to Helmholtzenables to production of a magnetic field calculable with high accuracy from the dimensions and the amperage. In series arrangement with an accurate ammeter field strengths of up to 800A/cm are produced. The dield room accessible both in axial and radial direction. Helmholtz coils with fluxmeters are also useful in testing of magnets. Helmholtz coils give repeatable results as against the search coils due to which the magnets can be compared with more accuracy for their total flux and in turn their quality. Field Generating and Field Detecting Helmholtz coils are designed as per user specifications.

Round Wire Coil Inductors
-
Round wire coil (RWC) inductors come in six platform sizes and enable the highest efficiency of any SMT inductor through the use of a low loss ferrite core material which minimizes AC losses and also eliminates thermal ageing. The use of round magnetic wire instead of rectangular flat coils enables a lower cost while still maintaining a low DCR and small footprint. The platforms have passed the AEC-Q200 stress test qualification proving the designs robustness and suitability to difficult environments but the parts are not IATF certified. The platform range from 7.6×7.4×6.4mm to 26x26x15mm and are suitable for a wide range of applications and markets including communications, computing and industrial.

Coil Analyzers & Power Supplies
-
Coil analyzers and power supply units are portable and lightweight devices intended for use in harsh switchyard and industrial environments. The typical application is switchgear and circuit breaker testing when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs with a very low ripple (<0,5%) enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers from different vendors.SAT40AD, POB30AD, and POB40AD are unique devices in the market due to their dual purpose:Power supply for coils and spring-charging motorsTesting circuit breaker’s coils, motor, and auxiliary circuitAll DV Power coil analyzers and power supply units have four separate outputs for opening and closing coils.SAT40AD has two powerful motor outputs (AC and DC) which can withstand up to 40 A inrush current.POB30AD and POB40AD have DC motor output rated up to 30 A and 40 A respectively. With the use of motor outputs, POB and SAT can also be used as a power source or a temporary battery charger.SAT40A II series instruments can be controlled via PC. The DV-Win application software is used to control both SAT and CAT (Circuit Breaker Analyzers & Timers) devices at the same time, making a unique test system for switchgear and circuit breaker testing.
