The scattering echo enables to read the case-hardened layer, ａnd provides digital display of highly accurate measurements.

This "HARD ECHO"is developed to measure the case-hardened layer by the ultrasonic scattering echo. The suitable selection of probe, holder ａnd measuring conditions enables to distinguish the boundary of the case-hardened layer ａnd the base metal.

Applications

The "HARD ECHO" can be applied for the various case-hardened components by high frequency induction heating such as automotive parts, construction machinery, machining tools, internal combustion engine ａnd various industrial machinery.

Features

High Sensitivity enabling to measure the near surface of products
Accurate Data Reading with high frequency high resolution & focused probe
Stable Transmission of ultrasonic beams by immersion method
Easy Operation by closed water column method
High Stability ａnd Accuracy with the optimum shaped probe fitting to products

Measurement Principle

The case-hardened layer has a fine metallographic texture than the non-hardened layer below it.
An ultrasonic pulse irradiated upon a workpiece whose case depth is to be measured is backscattered from the boundary between such two layers as an echo. By measuring the time from the injection of the pulse to the return of the echo, the case-hardened depth is calculated ａnd displayed on a CRT screen.
