No. 115: Measuring range for steel 1-225 mm at normal temperature, 4-100 mm for applications up to 300° Technical data: Test frequency: 7 MHz ELCOMETER ultrasonic wall thickness gauges from the MTG model series feature different measurement modes depending on the model version, MTG2, MTG4, MTG6 or MTG8, to produce measurement values with the greatest possible accuracy. Pulse-echo mode (P-E) Ideal for hole marks and material defect detection In this mode, the total thickness from the base of the measuring head up to the material thickness boundary line (usually the rear panel) is measured. Echo-Echo ThruPaint (E-E) In this mode, termed ThruPaint, the coating thickness is ignored and the material thickness is measured from the surface of the material to the material thickness boundary layer (usually the rear panel). A highly damped measuring head is required to use the Echo-Echo, ThruPaint mode. Sound velocity mode (VM) In sound velocity mode, the sound velocity of materials is measured. Ideal for determining the homogeneity of a material or alloy. For determining the correct sound velocity of a material for calibration. Scan mode Ideal for examining large surfaces. Measuring instrument records measured values at a measuring rate of 16Hz (16 measurements per second) During this process, the thickness is indicated live together with an analogue bar chart, which provides information on the thickness relative to the set zero value. Acoustic and visual warnings indicate deviations from the set boundary values. When the measurement head is removed, the average, lowest and highest thickness values are indicated. Sequence or grid lots Individual measurement values can be saved in up to 1000 alphanumeric sequence or grid lots. Where grid lots are used, the measurement values are saved in a type of calcu- lation table. Grid lots: The inaccessibility function allows inaccessible areas to be saved in the grid. B-image measurement value Time-based, two-dimensional cross-sectional B-image enables graphical depic- tion of material thickness Ideal for relative depth analysis The zoom view of the B-image can either be adjusted automatically or defined by the user. Discrepancy mode Determines the deviation from the set nominal value. Indicates areas of a material that are thinner or thicker than expected. Bar chart Analogue representation of current measured value Together with the highest, lowest and average measured value Chart is updated automatically when each measured value is recorded Ultrasonic wall thickness measurement Overview of measurement methods and functions 46100...
