Wheatstone Bridges


Equip your testing environment with portable, precise Wheatstone bridges and Kelvin double bridges from Transcat. The Wheatstone bridge is a device containing a divided bridge circuit for taking highly accurate resistance measurements. It captures the value of an unknown resistance, in comparison to known resistors within the circuit. Precision bridges provide exact resistance measurements in the miliohms (mΩ) to megohms (MΩ) range within their specified accuracies. We offer portable Kelvin double bridges, which are forms of the Wheatstone, designed to measure low resistance – with high accuracy. Transcat also stocks individual resistors, which provide resistance standards in low to high values. They operate in conjunction with potentiometers or bridges.


Electronic Bridge Designs


When ordering an electronic bridge, it is important to look at the design. We offer bridges with built-in resistors, power sources, and galvanometers that eliminate the need for auxiliary devices during measurement. Galvanometers are instruments that detect and measure electrical currents. When selecting electronic bridges, be sure to review the:


  • Ohm to Megohm measurement range
  • Measuring dials and multipliers
  • Accuracy
  • Temperature range
  • Power source
  • Maximum allowable input


Leading Bridge Development


Yokogawa leads our bridge selection for precise measurement. The manufacturer has engineered a Wheatstone bridge that comes with an integrated Murray and Varley loop tester and a power source for the efficient location of line faults. The brand also builds a precision Wheatstone bridge with a high-sensitivity transistorized galvanometer and power source. The Yokogawa 2769 is a compact Kelvin bridge model. It offers a low-resistance range from 0.1 ohm to 110 ohm. The Kelvin device features four multiplication plugs and includes a high-sensitivity DC galvanometer.
