flanged joint will have a shorter life than a sensor installed in the same joint once and used to monitor loads over a
prolonged period. After each installation, visually inspect your sensors for physical damage.
It is also important to keep the sensing area of the sensor clean. Any deposits on this area will create uneven
loading, and will cause saturation to occur at lower applied forces.
