Concrete dynamometer  Elastic Modulus Tester (Compressometer-extensometer)  DT-15

I. USE

For a certain object, there is a natural resonance frequency. When the volume and material of an object are constant, the resonant frequency of the object is only related to its density. The strength of an object is related to its density, so the natural frequency of vibration of an object determines its strength. If the resonant frequency of the object can be measured, the strength of the object can be calculated according to the strength theory. Kinetic instrument is an instrument used to measure the resonant frequency of objects. It is widely used in the fields of metallurgy, construction, bridges, hydropower and other fields to measure the elastic modulus of concrete, carbon, slate, glass, brick, plastic, and metal materials.

 II. Feature

1. The single chip microcomputer and integrated circuit are used to design and process data to realize the automation of the whole process of test calculation.

2. Equipped with RS232 communication port, with special analysis software, it can collect the inner line of frequency and amplitude, and accurately calculate the frequency elastic modulus.

3. It adopts Chinese liquid crystal display, and can collect and analyze special instruments and meters by software.

4. When manually measuring the frequency, the digital potentiometer is used to add and subtract the output frequency, which makes the measurement process simpler and more accurate.
