Description

Single-crystal delayed probe is employed by UM*3 precise ultrasonic thickness gauge. The multi-echo is used to enhance the accuracy with the resolution of 0.***1in and the low limit of 0.**2in. There are two operating modes of UM*3 ultrasonic thickness gauge: I-E (interface-echo) mode and E-E mode. The measuring range of I-E mode is 0.**9in*0.**9in, while the measuring range of E-E mode is 0.**2in*0.**4in.

Operating principle:

I-E (interface-echo) mode with single-crystal delayed probe

E-E (echo-echo) mode with single-crystal delayed probe

Measuring range:

1.5mm to *8mm; 0.**9in*0.**9in in I-E mode

0.*5mm to *0mm; 0.**2in*0.**4in in E-E mode

Depending on probe, material and surface condition

Digital resolution:

H＜0.4in : 0.***1in/ 0.**1in/ 0.*1in or 0.**1mm/0.*1mm/0.1mm

H≥0.4in : 0.**1in/ 0.*1in or 0.*1mm/0.1mm
