Thank you for the response.Nidum said:Please post a sketch of general layout of testing machine and provide basic some information about components to be tested
Nidum said:Are you trying to obtain the complete load / extension characteristic of the specimen or just the final load when it breaks ?
You may have problems making your machine frame strong enough if you just use bolted together Aluminium sections .
A load cell is a transducer that converts force or weight into an electrical signal. It works by using strain gauges, which are thin, flexible wires or foils that change resistance when stretched or compressed. When an object is placed on a load cell, it causes the strain gauges to stretch or compress, which changes the electrical resistance and produces a signal that can be measured and converted into a weight reading.
There are several types of load cells, including strain gauge, hydraulic, pneumatic, and capacitive load cells. Strain gauge load cells are the most common and use strain gauges to measure the deformation of a solid object. Hydraulic and pneumatic load cells use fluid pressure to measure force, while capacitive load cells use changes in capacitance to measure force.
Choosing the right load cell depends on several factors, including the maximum weight or force that needs to be measured, the environment in which it will be used, and the required accuracy and precision. It is important to consider the load cell's capacity, construction material, and calibration requirements when selecting the right one for your application.
Analog load cells produce a continuous electrical signal that varies in proportion to the weight or force being measured. Digital load cells, on the other hand, convert the electrical signal into a digital output, which can be displayed on a digital scale or read by a computer. Digital load cells offer greater accuracy and precision, but analog load cells are typically less expensive.
Maintaining and calibrating your load cell is important to ensure accurate and reliable measurements. It is recommended to regularly clean the load cell and check for any damage or wear. Calibration should be performed according to the manufacturer's instructions and may require specialized equipment. It is important to follow proper procedures and keep records of calibration to ensure the accuracy of your load cell.
