When conducting traixial tests on soil samples, it is observed that due to internal pressure, the cell expands, soil specimen consolidates resulting in the change of volume. Volume change gauge is therefore deviced to accurately measure volume changes. This is measured by observing the quantity of water entering or leaving the cell as the cell pressure and axial load are changed it is achieved by the displacement of free surface between the water supplied to the cell and another fluid (paraffin or kerosene). A dye is added to the paraffin for clear demarcation of the interface.
The unit consists of a glass graduated tube of the appropriate capacity graduated to parts of a ml. enclosed in a perspex tube sealed by two end caps. The unit is fitted with manifolds and valves which enable it to be used with the triaxial cell and the constant pressure (Mercury controls) system. The cell pressure can either be directly applied to the cell from the constant pressure system or through the volume change gauge. The graduated glass tube is not subjected to any difference in pressure and its inside is coated with a layer of silicon water repellent to reduce the error in meniscus. There is an arrangement for filling the unit with water and paraffin and a drainage valve is provided in the lower end cap. The whole assembly is mounted on a panel suitable for wall mounting. The unit is supplied complete with a pressure hose with end couplings and a packet of dye.
Salient Features

Single Burette 10ml capacity graduated in 0.05ml division
25ml capacity graduated in0.1ml division
Twin Burette 50ml. capacity graduated in 0.2 ml. divisions. The unit consists of two glass graduated burettes of 50 ml. x 0.2 ml. capacity enclosed in two perspex tubes sealed by two end caps. The manifold with valves enable the flow of fluid in the burettes to be reserved when the paraffin interfaces reach their limits in the burettes, the maximum capacity of measurement being only limited by the capacity of the mercury pots. The two burettes, enable the reduction in error in meniscus reading due to reversal of flow, the average of the two burettes being always taken as the volume change reading.

Precision Measurement for Laboratory Applications

Its automation grade is semi-automatic, utilizing microprocessor-based automatic control to streamline laboratory workflows.

Reliable Data Storage and Display

Equipped with internal memory for recording up to 100 tests, this device eliminates manual logging errors. The digital LCD ensures readings are clear and immediate, boasting a response time of 1 second and a resolution of 0.001 mm for meticulous documentation.

Durable Construction and Safe Operation

With materials including powder-coated mild steel and stainless steel, the gauge is resistant to environmental stresses. Safety interlocks, such as overload and over-travel protection, safeguard users and specimens during operation. The IP20 rating ensures adequate protection in laboratory environments.

FAQ's of Volume Change Gauge:

Q: How does the Volume Change Gauge measure volume changes in soil specimens?

A: The Volume Change Gauge utilizes a microprocessor-based control system with a highly sensitive digital LCD display to track volume changes in soil or construction material specimens. Its robust frame and stable measuring platform allow accurate detection of variations within the 0-10 mm range, with a resolution of 0.001 mm.

Q: What types of fluids and chemicals are compatible with this device during testing?

A: This gauge is compatible with fresh and saline water as well as light chemicals, ensuring versatility across a wide range of laboratory soil and material testing applications without compromising performance or safety.

Q: When should the internal memory be used, and what is its storage capacity?

A: Internal memory is useful for storing data from consecutive tests, reducing the need for manual recording. It can securely hold results from up to 100 tests, allowing efficient tracking and analysis of laboratory outputs over extended experimental runs.

Q: Where is the Volume Change Gauge typically installed or mounted in a laboratory setting?

A: Designed for bench-top mounting, the gauge is compact with a max height of 300 mm and width up to 100 mm. This allows easy installation in most laboratory environments, ensuring convenience for both set-up and operation.

Q: What processes are involved in calibrating and maintaining this equipment?

A: The instrument is factory calibrated and comes with a calibration certificate. Regular maintenance involves gentle cleaning, inspection of mechanical components for wear and ensuring the supplied calibration tools are used periodically to validate accuracy.

Q: What are the safety features included to protect users during operation?

A: The gauge incorporates overload and over-travel protection interlocks, helping to prevent accidental damage or unsafe situations during tests. These features ensure user safety as well as the integrity of test specimens throughout operation.
