Main functions and technical indicators of ASM8-15 residual stress detector

  • Source: Unknown
  • Date: November 30, 2021
  • Number of views: one hundred and three
1、 Overview    
The ASM8-15 static strain collector is a 15 channel static strain gauge with a 6-inch LCD screen. It mainly measures static strain, stress and residual stress. The A/D, CPU, memory, communication and other chips used in the strain gauge as well as the precision resistance of the bridge are selected from the international top electronic device manufacturers. Both the schematic design and the layout and wiring of the components on the circuit board have fully considered the temperature, humidity, vibration and other factors, as well as the impact of electromagnetic interference such as static electricity, pulse groups, electromagnetic radiation, etc, It has also carried out strict safety regulations tests on leakage current, insulation grade, insulation strength, etc., so it has high measurement accuracy, good linearity, small temperature drift, can work for a long time, safely and reliably, and can be widely and safely applied to strain and stress tests in industrial sites, enterprise research and development test centers, and university teaching experiments.
 
2、 Main functions     
1. Measure the static strain stress of various linear elastic materials, such as steel, cast iron, copper and its alloys, aluminum and its alloys, titanium alloys, magnesium alloys, rocks, concrete, composite materials, plastics, rubber, etc.    
2. Measure the internal residual stress (generated by extrusion, welding, casting, machining, etc.) of various isotropic elastoplastic materials, such as steel, cast iron, copper and its alloys, aluminum and its alloys, titanium alloys, magnesium alloys, rocks, concrete, plastics, rubber, etc.    
3. It can measure various physical signals
(1) Primary direct measurement signal: strain signal
(2) Signal generated by secondary calculation: stress signal, residual stress signal
4. It is equipped with a 6-inch LCD screen to display the strain, stress or residual stress of all channels online
Set and modify strain, stress or residual stress parameters through keys and knobs
5. Built in software storage function
(1) The data storage function enables the device to store the current measurement data at any time and view it afterwards.    
(2) Data import and export function, export Excel table data format file, convenient for viewing and further processing.    
                   
3、 Application field
1. Mechanical engineering and manufacturing equipment: strain, stress and displacement test on the force arm and other parts of construction machinery such as cranes, excavators, cement pump trucks, etc; Comprehensive test of pressure, displacement, temperature, strain and stress of oil cylinder; Residual stress test of machine tool guide.    
2. High speed railway, automobile, ship and other traffic equipment: comprehensive test of pressure, temperature and strain stress of engine and reducer; Strain test of vehicle body, wheel axle, high-voltage transmission bow and other parts.    
3. Power engineering: strength test of power plant equipment, such as overall strength test of nuclear power plant containment; Strain and stress test of turbine shaft and blade; Strain and stress test of steam pipeline after heating.    
4. Civil construction and water conservancy engineering: static strain stress test of building structure; Stress monitoring of steel structure roof of large stadiums and gymnasiums during removal and installation of supports.    
5. Bridges and roads: static load strength test of large steel structure bridges and structural stress test of road, culvert and tunnel works.    
6. Measurement of material parameters: measurement of elastic modulus, Poisson's ratio, residual stress release coefficient A and B of various metal materials.    
7. Metallurgy, petroleum and chemical industry: thermal stress test on the surface of ingot mold.
