Contact SupplierWe offer industrial kelvin bridge
usage : this bridge is very suitable for the use of wires and cables manufacturers. It is being extensively used for finding the resistance of transformer windings, contact resistance of relays etc.
Basic structure : terminals for battery, galvanometer, current and potential terminals are all provided on the bakelite panel enclosed in a teak wood box.
Range of measurement : the bridge has a range of 0.2 micro ohm to 11ohms. Maximum current : 10 amperes intermittently and 5 amperes continuously.
accuracy : + 0.05% + 1 small division of the slide wire
multiplying ratios : a rotary switch furnishes 5 multiplying ratios of x100, x10, x1, x0.1 and x0.01.
Standard resistance : there are 10 coils of 0.01 ohm each arranged on a rotary dial plus a circular slide wire of total resistance 0.01 ohm and 500 sub-divisions. Each sub-division is equal to 0.00002 ohms on the normal range. Current reversing switch : a battery reversing switch is provided to reverse the current in the bridge to eliminate thermal effects.
