Product Description

Carey Foster Slide Wire Bridge

Carey Foster`s Bridge Setup is used for the measurement of very low resistances, although it can be used to find small differences between large resistances. It can measure the decimal value of resistance. Our Carey Foster`s Bridge Setup consists of two parts, bridge arrangement and testing unit.

The Testing unit contains DC Power Supply, Galvanometer and unknown resistances on a single board. DC Power Supply solves the problem of discharging of battery or a cell with respect to time which affects the result. Sensitivity of Carey Foster`s Bridge is the same as the sensitivity of the Wheatstone Bridge as it uses the same fundamental principle.

Carey Foster`s Bridge Setup is an ideal platform to enhance education, training, skills & development amongs our young minds.

Product Features

Precise Bridge arrangement
Galvanometer, unknown resistances and DC Power Supply are provided on a single board
Low temperature coefficient Constantan wire
DC Power Supply in place of a cell or battery

High Accuracy and Advanced Design

This Carey Foster Bridge Setup provides an impressive measurement accuracy of 0.01 ohm, ensuring precise detection of small resistance differences. Its advanced features, such as a polished wooden base, precision sliding jockey, and engraved metal scale, are tailored for demanding laboratory environments. Durable materials like bakelite, brass, and high-quality constantan wire contribute to the devices robust and lasting structure.

User-Friendly and Reliable Operation

Engineered for effortless tabletop use, this bridge is factory calibrated for immediate operation. The dual resistance coil holders support comparative measurements, and the analog display via galvanometer makes readings straightforward. Insulated end supports help prevent measurement errors, while shock-resistant components enhance safety during routine operations.

FAQs of Carey Foster Bridge Setup:

Q: How do I operate the Carey Foster Bridge Setup for measuring resistance?

A: To use the Carey Foster Bridge, connect your unknown resistances to the brass terminals using the dual coil holders. Adjust the precision sliding jockey along the constantan wire to balance the bridge, then read the value on the engraved metal scale. A galvanometer detects the balance point, and the device is powered manually, with an external battery needed for the galvanometer.

Q: What are the primary benefits of using a Carey Foster Bridge in a laboratory setting?

A: This bridge offers highly accurate detection of small resistance differences, with a resolution of 0.01 ohm. Durable construction, factory calibration, and shock-resistant components make it a dependable option for educational and research laboratories looking for both precision and longevity.

Q: When is it most appropriate to use this Carey Foster Bridge setup?

A: The device is best suited for indoor laboratory use, especially when you need to compare and measure small differences in electrical resistance between two components. Whether for academic experiments or quality control, it excels in controlled laboratory environments.

Q: Where should the Carey Foster Bridge be installed or used?

A: This instrument is designed for tabletop mounting within indoor laboratory environments. Its insulated supports and protective foam-lined box make it safe and easy to handle and store when not in use.

Q: What process ensures accurate results with the Carey Foster Bridge?

A: Begin by securely mounting the device on a stable table and connecting the resistances to be compared. Use the sliding contact to achieve a balanced measurement indicated by zero deflection on the galvanometer. The engraved metal scale provides precise readings, while insulated supports and high-quality materials reduce measurement errors.

Q: What materials are used in the construction of this bridge, and why?

A: Key materials include high-quality constantan wire (for stable resistance), brass terminals (for low contact resistance), bakelite, and a polished wooden base. These materials were chosen for their durability, accuracy, and capacity to minimize errors during sensitive resistance measurements.
