Product Code : SCL-EELE-12351
Indian Lab Suppliers supplies the Kelvin Bridge Trainer (Product ID: 12351) as part of its electronics engineering lab equipment range. It is a PCB-based training board for studying the Kelvin bridge.
Quick Answer
The Kelvin (double) bridge is a Wheatstone bridge variant that adds a second set of ratio arms so that lead and contact resistance do not upset the measurement of low resistances. This board has a 1 kΩ and a 10 kΩ 10-turn helical potentiometer with dials, and fixed resistances of 10 MΩ, 1 MΩ, 100 kΩ, 10 kΩ, 1 kΩ, 100 Ω and 10 Ω chosen by selector switch. It is built on a screen-printed glass-epoxy PCB with test points, a power LED and 2 mm patch cords. A sine output is listed for the board; please confirm the supply, excitation and detector arrangement at quotation.
