The Tubing Force Gauge measures the compressive and tensile forces at specific locations within the tubing string by measuring and recording axial strain, temperature, and internal and external pressure. The pressure and temperature are valuable data on their own, but also required to calibrate the strain measurement to deliver an accurate force. The tool withstands 50g acceleration and records 10 million samples at 10 samples per second powered by 4 replaceable AA batteries. All data is easily downloaded by USB.
