Vaiseshika Electron Devices supplies Portable Wheatstone Bridge. Vaiseshika Electron Devices Quality Management System is ISO 9001:2000 compliant. The Portable Wheatstone Bridge of Type: 9401 has been specially designed for the measurement of resistances in the range 0.01 ohm to 1.0 Megohm. The resistance measurement spectrum provided in the equipment is coupled with excellent accuracy of the order of ± 0.05%. These exquisite capabilities have been realized in this equipment by using non-inductive imported manganin wire. In addition, precision phosphor-bronze silver plated band switches have been utilized to minimize the contact resistance errors to 0.0005 ohm per switch. The manganin coils have been subjected to long ageing process to eliminate the possible variations in the resistive value due to climatic temperature variations. All the coils have been properly insulated with high grade insulation material to arrest the variation in the values.

In this Portable Wheatstone Bridge, a built-in taut suspension galvanometer, having high order sensitivity and resolution, has been provided to obtain a very sharp and accurate null point. This galvanometer has been provided with built-in systems to obtain critical damping conditions in all settings along with constant terminal resistance. Terminal connections are available in the instrument to connect the bridge to an external battery for more precision measurements. The Portable Wheatstone Bridge, Type 9401 has multiple facilities. This instrument can be used to measure the resistances with ± 0.05% accuracy. It can also be used to locate faults in cables by Varley and Murray Lop Test. Portable Wheatstone Bridge finds applications in cable manufacturing industries, Telecommunication Equipment Industries, Chemical, Petro-complex and refineries, Instrumentation, Electronic equipment centres, etc. .
