Product Overview
The Anderson Bridge (With Bridge Oscillator & Null Detector) is a sophisticated electrical measurement instrument designed for high-precision analysis of resistance, capacitance, and inductance in alternating current (AC) circuits. Engineered with laboratory-grade components, this bridge eliminates measurement errors through its integrated null detector, which identifies balance points with exceptional accuracy. The built-in bridge oscillator generates stable AC signals, ensuring consistent performance across frequency-dependent experiments. Unlike traditional Wheatstone bridges, the Anderson configuration minimizes stray capacitance effects, making it ideal for applications requiring micro-level sensitivity. The unit features a robust copper-based construction for durability and signal integrity, while its compact benchtop design optimizes workspace efficiency. Whether used for component characterization or circuit calibration, this bridge delivers repeatable results with minimal thermal drift. The null detection mechanism employs a sensitive galvanometer alternative, providing visual balance confirmation without parallax errors. Compatible with standard laboratory power supplies, it requires no additional signal conditioning for most applications. The instrument’s design adheres to IS/IEC standards for electrical measurement devices, ensuring compliance with Indian academic and research protocols.
FAQs
1. What is the frequency range supported by the built-in oscillator in this Anderson Bridge?
The oscillator typically operates within the 50Hz to 1kHz range, which covers most standard laboratory measurement requirements for AC bridge circuits.
2. Can this bridge measure both resistance and capacitance simultaneously?
While primarily designed for separate measurements, the bridge configuration allows sequential analysis of resistance and capacitance by adjusting the circuit connections and balance conditions.
3. What power supply specifications are required for operating this bridge?
The unit functions with standard 230V AC laboratory power supplies, though some configurations may require additional DC adaptation for the null detector circuit.
4. How does the null detector in this model differ from traditional galvanometers?
This bridge employs an electronic null detector that offers higher sensitivity than mechanical galvanometers, reducing measurement time and improving accuracy in low-signal conditions.
5. Are there any specific environmental conditions required for optimal performance?
For best results, maintain ambient temperatures between 15°C to 35°C and relative humidity below 80%, as excessive moisture or temperature fluctuations may affect component stability.
