The CMX measures thickness, detects internal pitting on coated pipes and tanks while also measuring the coating thickness.
Simply and cheaply!"
Only* the CMX can accurately measure:
BASE MATERIAL THICKNESS
* simultaneously and economically
The CMX is a new concept in Multi-Mode Ultrasonic Thickness Gauges
This as achieved in a single mode called "PECT" (pulse-echo coating).
Other measuring modes have the following “issues”
0-1st Echo is effective for pitting detection but the measurement does not properly compensate for the coating thickness
Echo-Echo is effective for thru-coating measurements, properly correcting the measurement for the coating thickness but is poor at detecting pitting.
Measurement Modes built-into the CMX:
Coating on: Pulse-Echo Coating (PECT)
Coating off: Pulse-Echo (P-E)
Temp Comp: Pulse-Echo Temperature compensated (PETP)
Thru-Paint: Echo-Echo (E-E)
Coating Only: Coating (CT)
Overview of the CMX & CMX DL:
The CMX gauges are based on 100 MHz DSP platform which offers many new features and advantages.
"PECT" is a hybrid mode utilizing some special techniques based on wave theory and processing power. Since the CMX can locate pits and defects, as well as measuring the coating thickness.
The Pulse-Echo mode has always been used for locating blind sided pitting and internal defects.
The Echo-Echo mode was used to eliminate the error caused by coated surfaces to provide a nominal material thickness.
With other gauges the user has to switch between modes, giving up either thru-coating capability or pitting detection. With the CMX's new "PECT" mode you have the capabilities of both modes at the same time !

Pulse-Echo Coating (PECT)
Measures both coating and base material thickness with sensitivity to back-wall pitting.
Measure uncoated materials with sensitivity to back-wall pitting.
Pulse-Echo Temperature compensated (PETP):
Automatic Probe Zero compensation prevents reading drift due to temperature induced velocity changes in the probes delay lines
Measures base material thickness while ignoring the coating. This mode is not sensitive to back-wall pitting.
Measure coating thickness only. Good for measuring coatings on concrete, tanks, bridges, etc.
