Product Description
DTM-II Elastic Modulus Tester
I. DTM-II Dynamic Elastic Modulus Tester for Graphite Carbon Materials Overview
Every object has an inherent resonant frequency. When the volume and material of an object are fixed, the resonant frequency of the object is only related to its density. The strength of an object is related to its density; therefore, the inherent vibration frequency of an object determines the strength of the object. If the resonant frequency of the object can be measured, the strength of the object can be calculated based on the strength theory. This instrument is used to measure the resonant frequency of an object to calculate the elastic modulus of the object. It can be used to measure ceramics, graphite, glass, plastics, metals, etc. It is widely used in various production enterprises, scientific research units, universities, and quality inspection departments. Instrument reference standards: GB/T3074.2-2008 "Determination Method of Elastic Modulus of Graphite Electrodes", GB/T5594 Young's Modulus Test Method, and GB/T 2105, GB22315-2008 Metal Material Elastic Modulus Test Method, etc.
This instrument uses an imported data acquisition and control card, controlled by a computer, to achieve full automation of testing, calculation, and reporting.

III. Dynamic Elastic Modulus Tester for Graphite Carbon Materials Working Principle
The computer controls the data acquisition control card to output a sine wave signal from small to large to the transmitting probe. The oscillation of the transmitting probe is transmitted to the sample, forcing the sample to perform mechanical vibration. When the emission frequency is the same as the inherent frequency of the sample, resonance will occur. At this time, the vibration amplitude of the sample will reach an extreme value. The data is transmitted through the receiving sensor probe to the data acquisition control card and then back to the computer. The computer finds the resonant frequency according to the frequency scan and then calculates the elastic modulus based on the sample weight and dimensions input to the computer.
Instrument configuration: Includes one DTM-II dynamic elastic modulus tester main unit (including an imported data acquisition card), one set of exciter and receiver, one set of test stand and connecting lines, one set of software, and one desktop computer.
Note: Support-type or hanging-type testing methods are optional.
