Olympus 45MG Ultrasonic Thickness Gauge is an advanced ultrasonic thickness gauge packed with standard measurement features and software options. This unique instrument is compatible with the complete range of Olympus dual element and single element thickness gauge transducers, making this innovative instrument an all-in-one solution for virtually every thickness gauge application.
Using Dual Element Transducers
One of the major applications of the Olympus 45MG Ultrasonic Thickness Gauge is measuring the remaining thickness of pipes, tubes, tanks, pressure vessels, ship hulls, and other structures affected by corrosion or erosion. Dual element transducers are most commonly used for these applications.
- Automatic Probe Recognition for standard D79X series dual element transducers
- Calibration Doubling warning when echo doubling may occur during calibration
- The Echo-to-Echo / THRU-COAT® option allows for measurements on painted and coated surfaces
- High temperature measurements; up to 500 °C (932 °F)
B-scan Mapping (Time-based)
The Olympus 45MG Ultrasonic Thickness Gauge B-scan feature converts live thickness readings into cross-sectional images drawn on the display. This standard feature is very helpful in viewing the changes in thickness measurements over a distance. The B-scan is activated as soon as the transducer makes contact with the surface of the material. The Freeze Minimum function is used to display the minimum thickness of the scanned area. The optional 45MG datalogger can store up to 10,000 thickness readings in a single B-scan.
High Temperature Surfaces
Olympus 45MG Ultrasonic Thickness Gauge is ideally suited for making stable thickness measurements on hot material surfaces (up to 500 ºC or 932 ºF) with the D790 series transducers (D790, D790-SM, D790-RL, and D790-SL). The Zero Compensation feature of the Olympus 45MG Ultrasonic Thickness Gauge enhances the accuracy of measurements on hot surfaces by compensating for temperature changes in the transducer delay line due to thermal drift.
