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
: The bridge has a range of 0.2 micro ohm to 11ohms.
Range Multiplying Least Factor Count
2 Milli ohm to 11 ohm x 100 2 Milli ohm
0.2 Milli ohm t o 1.1 ohm x 10 0.2 Milli ohm
20 Micro ohm to 11 ohm x 1 20 Micro ohm
2 Micro ohm to .011 ohm x 0.1 2 Micro ohm
0.2 Micro ohm to .0011 ohm x 0.1 0.2 Micro ohm
Maximum Current : 10 amperes intermittently and 5 amperes continuously.
Accuracy : + 0.05% + 1 small division of the slidewire.
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 slidewire
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
AP-672B(ii) INDUSTRIAL KELVIN BRIDGE Same as above but with an additional range factor of x1000
to give the range of measurement as 0.2 micro ohms to 110 ohms.
Basic Structure :The unit consist of a variac, a step down transformer, a bridge rectifier circuit
and an ammeter of 0 - 10 amp to read current. Two heavy brass terminals are provided for output.
Input Voltage : 230 Volts AC mains 50 c/s.
D. C. Output : Approximate 0 - 10 C, Continuously adjusted to give a variable current of 0-10
Amperes depending upon external load.
It is an arrangement to hold specimens in the form of wire, rods strip etc. separate current
and potential terminals are provided. Distance between potential point is 500 mm. It can
hold specimen of any size between 1/2" dia rod to 42 S.W.G. wires.
