Industrial Kelvin Bridge

Standard Resistance: There are 10 coils of .01 ohm each arranged on a rotary dial plus a circular slide wire of total resistance .01 ohm and 500 subdivisions is equal to .00002 ohms on the normal range. Multiplying Ratios : A single rotary switchfurnisher 5 multiplying ratios of x 100, x 10, x 1, x .01 and x 0.01.Range of measurement : The bridge has a range of .0000002 ohm to 11 ohm.Max. Current : 10 A intermittently & 5 A continuously.Panel : A bakelite panel enclosed in a teak wood box is used. Separate current and potential terminals, battery and galvanometer terminals, push buttons for battery and galvanometer are provided on the panel.Accuracy : ± 0.5% current 5Amps upto 10Amps.Coils : Mangnin coils are used.
