Fully Automatic Transformer Winding Resistance Tester

-

Neutronics Manufacturing Co.

Neutronics Manufacturing Co.

Measure DC resistance of transformers windings etc. Introduction: The NMC ''TDR'' is a high precision, new generation, light weight large output current and micro-processor controlled tester. This replaces old DC wheat stone bridge and double arm bridge for measurement of DC resistance. ''TDR'' adopts new advanced test current power supply technology, four terminal measurement, digital display of resistance value and test current. ''TDR'' is powered by 220V AC mains single phase supply. The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning.Principle: The constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation.

Standard Helmholtz Coils

-

Magnetic Instrumentation Inc.

Magnetic Instrumentation Inc.

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.
