Open Circuit Locator
A994
-
The A994 is an open circuit locator for electric and telephone cables wind on the reel; it gives the position of the fault from the inside or outside end of the cable, in percentage to the total cable length. The instrument measures the ratio of the capacitances of the two sections of failed conductor using two high precision i/v converters. The advantage of this method is due to the fact that the measurement error depends almost exclusively on the dimensional inhomogeneity of the cable. The A994 has the unique feature to permit the location of fault in cables with all broken wires. This instrument locates breaks in cables with a total capacity between 2 nF and 5 uF. The distance to fault is displayed on a large LCD display.

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.
