Flat Jack Test can be used to determine in-situ Stress, Deformability and Resistance of masonry or other structures. This test is carried by cutting a slot into the structure to accommodate flat jacks or two, keeping the second jack at perpendicular to the previous one. This flat jack is than pressurized to desire level and related strains in adjoining area is read. For Stress measurement a single flat jack can be used BUT for deformability and Resistance.

FAQ's of Flat Jack Test Insitu Stress Measurement Apparatus with Data Logger:

Q: How does the Flat Jack Test Insitu Stress Measurement Apparatus measure stresses within a structure?

A: The apparatus utilizes a flat jack inserted into prepared slots in masonry or concrete. When pressurized with hydraulic oil, the high-sensitivity pressure transducer measures the force required to restore the original state. The digital data logger then records the in-situ compressive stress values accurately.

Q: What data logging and transfer options does the system offer for field use?

A: Data is stored in the apparatus's internal memory, and users can download it easily via a USB connection. Additionally, the data logger supports both USB and RS232 connectivity, making it compatible with a range of data management systems for post-test analysis.

Q: When is field re-calibration recommended for this apparatus?

A: Although the system is pre-calibrated, field re-calibration is recommended periodically-particularly after extensive use, before critical testing sequences, or if there is any indication of abnormal readings during operation to ensure continued measurement accuracy.

Q: Where can the insitu stress measurement apparatus be effectively utilized?

A: This apparatus is designed for on-site, construction, and laboratory environments, making it suitable for use in the assessment of masonry walls, concrete structures, and other settings where accurate in-situ stress measurement is required.

Q: What is the process for conducting an in-situ stress test using this equipment?

A: The process involves mounting the flat jack in a pre-cut slot, connecting hydraulic hoses, and using the manual pump to pressurize the jack. The pressure transducer records stress levels, while the digital data logger captures and displays readings in real-time for precise documentation.

Q: How does using this apparatus benefit construction or inspection workflows?

A: Its portable design, real-time digital data logging, and high measurement accuracy streamline stress analysis tasks, improve the reliability of structural assessments, and facilitate compliance with international testing standards such as IS 11093 and ASTM C1197.
