A strain gauge generally known as strain gage is a sensor which has the resistance power that differs according to the applied force. It has the capacity to convert the applied force, pressure, tension, weight into a changed electrical resistance that can be measured later. This strain gauge data logger is a device that consists of a sensor which can measure the force into changed electrical resistance. The time when external forces are applied to an object at rest, stress and strain occur as a result of the applied force. The stress that is caused is said to be the internal resistance force of the certain object. The strain is the displacement or deformation of the object that occurs due to the applied force. Vacker Africa supplies Strain Gauge Data Logger in various countries of Africa such as Kenya, Djibouti, Tanzania, Chad, Angola, Libya, Algeria, Niger, Congo, South Africa, Ethiopia, Rwanda, Morocco, Nigeria, Ghana, Congo-Pacific, Zimbabwe, etc.
