Ultrasonic Thickness Gauge

เครื่องวัดความหนาโลหะ Model CMXDL

CMXDL
Data-Logging Ultrasonic Coating & Wall Thickness Gauge

The new CHECKLINE® CMXDL measures both coating and wall thickness quickly and accurately—from only one side. In addition, when switched to Pulse-Echo mode, the CMXDL automatically measures and eliminates the coating from the wall thickness measurement, enabling the user to locate the finest corrosion and pitting—without removing the coating.
Oversized graphic LCD is backlit and features easy to read fonts, graphics and display codes showing all critical settings including Velocity, Operating Mode, Alarms, Scan Mode and more. The backlight can be set to ON (always-on), OFF (always-off) or AUTO (automatically-on when measuring).


Five user-selected operating modes are included:

Coating On: Measures wall thickness using Pulse-Echo. It separately displays wall & coating thickness.

Coating Off: Measures wall thickness using Pulse-Echo. It displays wall thickness only.

Temperature Compensated: Measures wall thickness using Pulse-Echo and automatically adjusts calibration to compensate for changes in material temperature.

Thru-Coat: Measures wall thickness only using Echo-Echo. (coating is NOT included)

Coating Only Mode (CT): (Coating Thickness) Measures from 0.0005 to 0.100 inches (0.013 to 2.540 mm). Range will vary slightly depending on the coating.

 Complete Kit
The CMXDL is supplied as a complete kit with the gauge, probe, 4 oz. bottle of coupling fluid, 2 AA batteries, NIST-Traceable Calibration Certificate, operating manual, RS-232 cable and data-transfer software all in a foam-fitted carrying case.

 High Speed Scan Mode & B-Scan Mode

Hi-Speed Scan Mode	B-Scan Mode
Scan Mode measures 64 times per second, displaying the max and min reading measured during the scan interval. Sample rate is 200/sec when coating measurement is off.	The B-Scan displays a time based cross section view of test material of the contour of the blind, or underside of a pipe or tank application. the B-Scan view draws at a rate of seven seconds per screen from right to left.
