Category: Physics

Model No:P-672B(i)

  • 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 woodbox.
     

Product Description

  • 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 ofthe 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 ohmeach 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.
