About Lateral Extensometer
Specification:
The unit consists of two movable frames pivoted at one end. The extensometer is fixed to the specimen with the help of tightening screws. The lateral extension is indicated on a dial gauge of 0.002 mm x 5 mm is mounted on the upper ring and the tip of the dial gauge rests on an anvil. The zero on the dial gauge can be set by adjusting the anvil screw. Supplied in a wooden carrying case.
Engineered for Precision and DurabilityConstructed from mild steel with a protective chrome finish, this lateral extensometer combines durability with high precision. Hardened steel contact points and cast iron clamps ensure reliable performance and extended service life, even in demanding laboratory conditions. Its maintenance-free, mechanical design and resistance to corrosion make it an excellent investment for consistent, long-term use.
Efficient Manual Operation and CompatibilityDesigned for manual operation, this gauge works seamlessly with a variety of compression testing machines. No external power supply is required, enabling accurate, immediate readouts via a clear dial display. The device accommodates standard cylindrical specimen sizes as per IS/BIS specifications and is portable for easy transport between testing stations.
FAQ's of Lateral Extensometer:
Q: How does the Lateral Extensometer measure lateral strain?
A: The Lateral Extensometer is mechanically clamped onto a standard cylindrical specimen. As the specimen undergoes compression or tension testing, the dial indicator immediately registers the lateral displacement, allowing for precise observation of strain up to 6 mm with an accuracy of 0.01 mm.
Q: What types of samples can be tested with this device?
A: This extensometer is designed to measure standard cylindrical specimens, such as those with a 38 mm diameter or other sizes specified by IS/BIS standards. It is suitable for use in various laboratory and material testing scenarios.
Q: When is it appropriate to use a lateral extensometer?
A: A lateral extensometer should be used during compression or tension tests when it is necessary to assess the deformation characteristics of materials, specifically their lateral strain. It is ideal for laboratory settings conforming to IS: 1528 or ASTM D2166 requirements.
Q: Where can this extensometer be used safely?
A: The device is suitable for laboratory environments with temperatures from 10C to 40C and humidity levels up to 90% RH (non-condensing). Its chrome-coated, corrosion-resistant construction enhances durability in such environments.
Q: What is the benefit of its mechanical dial gauge and manual operation?
A: The mechanical dial gauge ensures instantaneous, high-resolution readings without reliance on a power source. Manual operation increases reliability and simplifies maintenance, making it especially valuable in diverse or resource-limited laboratory settings.
Q: How is the extensometer mounted and used during testing?
A: It is mounted onto the specimen using mechanical clamps with hardened steel contact points. The instrument is then manually positioned and adjusted, after which the dial gauge tracks lateral strain as the sample is subjected to testing in a compatible compression machine.
