High Precision Measurement

Utilize the Linear Expansion Apparatus to achieve accurate measurements, thanks to a high-sensitivity dial indicator (0.01 mm least count). This allows for detection of minute changes in rod length during thermal expansion experiments, supporting robust scientific research and reliable educational demonstrations.

Versatile Rod Compatibility

The apparatus supports brass, aluminium, and steel rods of up to 500 mm in length, facilitated by its adjustable clamps and robust stainless steel tube construction. Interchangeability between rod materials offers a practical way to compare thermal properties across different metals.

Efficient Thermal Control System

A built-in 250 W immersion electric heater and water jacket provide uniform heating and rapid cooling of rods. The fiber sheet enclosure serves to insulate the system, maintaining stable temperatures up to 100C, so experimental conditions closely match intended parameters.

FAQs of Linear Expansion Apparatus:

Q: How does the Linear Expansion Apparatus measure expansion accurately?

A: The apparatus uses a dial indicator with a sensitivity of 0.01 mm to precisely register the change in rod length caused by temperature fluctuations. The manual operation allows stepwise heating and gradual cooling for accurate readings.

Q: What process should be followed for using the apparatus?

A: Start by securing a brass, aluminium, or steel rod in the adjustable clamps. Initiate heating using the 250 W immersion electric heater and record readings as the rod expands. Cool the rod through the water inlet and outlet system to observe contraction, tracking all changes using the dial indicator.

Q: When is water cooling necessary in the experiment?

A: Water cooling is necessary after the rod has been heated to the desired temperature, typically up to 100C. The water inlet and outlet are used to pass water through the jacket, enabling controlled cooling and accurate measurement of contraction phases.

Q: Where can the Linear Expansion Apparatus be used?

A: This apparatus is suitable for school, college, or research laboratories. Its durable design and manual operation make it versatile for standard experiments involving measurement of thermal expansion in metals.

Q: What are the benefits of interchangeable rods in this apparatus?

A: Interchangeable rods allow users to measure and compare the expansion rates of different metals, such as brass, aluminium, and steel, under similar conditions. This enhances the educational value and flexibility of experiments.

Q: How does insulation improve experimental results?

A: The fiber sheet enclosure reduces heat loss to the surroundings, maintaining a consistent temperature gradient along the rod. This insulation ensures that the measurement reflects only the thermal expansion of the rod itself, improving data reliability.
