Electronic Extensometer

We are offering Electronic Extensometer.Features:This instrument is to be used on Tensile or Universal testing machines to find out Proof stress & Young's modulus values.In the case of many brittle materials such as high carbon steels, alloy steels, light aluminum & magnesium alloys, it is difficult to get yield values. For such materials stress corresponding to a certain allowable amount of plastic deformation is termed as proof stress say 0.1% or 0.2% proof stress.The measuring range is up to 5mm & resolution is 0.001mm.Standard two fixed gauge lengths of 25 & 50 mm are provided. Different sizes gauge lengths can also be given at an additional cost.If this extensometer is ordered with a computerized UTM, then a special menu is driven application software is provided, which accepts load & extension values, & evaluates proof stress values.The measurement accuracy satisfies all requirements of class-I as per IS:12872-1990.Specifications:Model: EE-2Accuracy: Class 1 as per IS 12872 / ISO 9513Type: Strain Gauge typeOut-put: 0.3 mV / V / mm. (approx)Excitation: 10 V. DC NominalMeasuring range: 2, 5 , 10, 20 mmNominal resistance of bridge: 350 ohmGauge length: 25 mm/50mm by means of extenderResolution: 0.001 mm
