The Elcometer MTG & PTG range has a choice of measurement modes allowing the user to select the most appropriate for their application.
|The Display |
All gauges have a fully customisable, scratch and solvent resistant colour LCD display. Measurement modes available include Pulsed-Echo (P-E), Echo-Echo ThruPaint™ (E-E), Interface Echo (I-E), Plastic Mode (PLAS) and Velocity mode (for more information on measurement modes, see page 3). A choice of measurement units are available, depending on the measurement mode selected. A stability indicator shows clearly both the strength and reliability of the ultrasonic signal.
|Scan Mode |
When enabled, users can slide the transducer over a large surface area whilst the gauge takes readings at a rate of
16 Hz (16 readings per second). During each scan, the live thickness is displayed together with an analogue bar graph showing the thickness relative to the set nominal and any user defined limits, with audible and visual warnings if any readings fall outside set limits. When the transducer is lifted off the surface, the average, lowest and highest thickness value is displayed making scan mode ideal for checking a sample’s overall uniformity.
|Run Chart |
A trend graph of the last 20 readings, showing the variation in material thickness over the test area. The graph is updated automatically as each reading is taken and any readings outside the set and enabled limits are displayed in red thus allowing the user to easily identify areas where corrosion may be present or the material is too thick for purpose.
|On Screen Statistics |
Up to 8 statistical values can be displayed from a choice of number of readings (η) , lowest, highest and average reading (Lo, Hi x ), standard deviation (σ), low and high limit values, nominal value and range.
|Velocity Mode |
Velocity mode measures the speed of sound of materials and is ideal for determining the homogeneity of a material/alloy and the correct velocity of a material for calibration.
Sequential or Grid Batching
* Grid batches only
|B-Scan Reading |
A time based, cross sectional 2 dimensional B-Scan provides a graphical view of the material under test, ideal for relative depth analysis. The zoom of the B-Scan reading can either be set to automatic or can be defined by the user to focus on areas of interest.
|Differential Mode |
Once a user defined nominal thickness value has been set, the gauge displays the measured thickness together with the variation from the set nominal value thus indicating areas of the material which are thinner or thicker than expected.
|Bar Graph |
An analogue representation of the current measurement value together with the highest (Hi), lowest (Lo) and average (x) reading. The graph is updated automatically when each reading is taken.
||Plastic Mode |
Plastic mode is specifically designed for measuring very thin plastics.
