27MG Ultrasonic Thickness Gauge
Standard thickness gauge functions:
- automatic recognition of the converter to ensure its optimal operation;
- automatic zero compensation to ensure accurate measurements on hot surfaces;
- gain adjustment when measuring materials with a high degree of ultrasonic attenuation (cast metal);
- differential mode;
- high / low alarm threshold settings;
- Min / Max mode to call the minimum or maximum thickness value (20 measurements per second).
The 27MG is designed for inspection and maintenance engineers measuring the thickness of objects that are corroded from the inside (metal pipes, tanks, beams, and supporting structures). An ultrasonic thickness gauge is a cost-effective and quick way to conduct non-destructive testing using ultrasound.
Converters
To work with a 27MG thickness gauge, a separately-combined transducer is required, which is used to measure the thickness of many corroded objects. To measure the thickness of materials that are too thick, too thin, or small pipes, Olympus offers a wide range of separately coupled transducers. Olympus converters compatible with 27MG have an automatic recognition function; This function optimizes the operation of the probe, causing a default V-path correction.
