Industrial Double Bridge

Industrial Double Bridge

Product Code : JA-SI-8046

The Industrial Double Bridge (SKU JA-SI-8046) measures low resistances from 2 micro-ohm to 11 ohm, where lead and contact resistance would upset an ordinary Wheatstone bridge. Its standard resistance is ten manganin coils of 0.01 ohm on a rotary dial plus a circular slide wire of 0.01 ohm total with 500 divisions, so each division is 0.00002 ohm on the normal range. A single rotary switch gives five multiplying ratios, and separate current and potential terminals are provided.

Frequently asked questions

What range does the industrial double bridge measure?
From 2 micro-ohm to 11 ohm.

What current can it carry?
10 A intermittently and 5 A continuously; accuracy is +/-0.5% for currents of 5 A to 10 A.

Why does it have separate current and potential terminals?
So that lead and contact resistance do not affect the low-resistance reading.
