Portable Wheatstone Bridge
Resistance Range | 0.01 ohm to 1.0 Megaohm |
Series Arm | 10 x 1000, 10 x 100, 10 x 10, 10 x 1 ohm totaling to 11,110 ohms |
Ratio Arm | Seven ratio arms having the multiplier of x 1000; x 100; x 10; x 1; x 0.1; x 0.01; and 0.001 |
"Vaiseshika" Portable Wheatstone Bridge Type 9401 has been specially designed for the measurement of resistance 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 (German Make). In addition, precision phosphor-bronze silver plated band switches have been utilized to minimise 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.
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. Similarly any spot deflection galvanometer can be equally connected externally at separate terminations. "Vaiseshika" Portable Wheatstone Bridge Type 9401 has multiple facilities. The same instrument can be used in different universal applications. The instrument can be used to measure the resistance with ±0.05% accuracy. It can also be used to locate faults in cables by Varley and Murray Lop Test. Above all the instrument can be used as standard resistance substitution box of accuracy ±0.05%. This instrument can find indispensable applications in cable manufacturing industries, Telecommunication Equipment Industries, Chemical, and refineries, Instrumentation, Electronic equipment centers, research and development centers and educational/engineering institutions.
Features:
- Ideal for fault location in cables by Varley and Murray Loop Test
