Characteristics of the material used in the test specimen and its internal flaws can be detected by measuring the velocity and attenuation of a sonic-ultrasonic wave while passing through the test specimen. The hardware is designed for wideband operation and amplification over wide dynamic range of signals. Special enclosure is designed for transducers and cables for fire safe operation. It has security features built-in for use in non-destructive testing in areas handling explosives. SOUNDS MK2 R4 is the first equipment of its kind developed in India for the solid motor segment inspection.

Echosounder

Echosounder is a product developed by C-DAC for Indian navy, for use in ships for measuring depth of sea water. The equipment is being manufactured by KELTRON based on a ToT agreement with C-DAC. The upgraded version supports synchronized operation (with other sonar systems) as well as mine hunting sonar and has successfully completed sea trials.

Acoustic Landmine Detection System (ALMS)

ALMS can be fitted on BMP vehicles (amphibious infantry fighting vehicle) such that the measurement of characteristics of the vibrations transferred to ground by BMP vehicle while moving can be used for detection of buried land mines. ALMS uses a separate earth exciter for generating the interrogation beam which would lead to an optimally designed ground exciter for ALMS.

Ultrasonic Diameter Measuring System (UDMS)

C-DAC has taken up a project to develop a high precision measuring system of diameter of heat-resistant composite alloy pipes employed in power plants based on ultrasonic principles. The technology can also be used in a wide variety of applications such as precision liquid level measurement, precise machinery control in industries, robotic control, non-destructive testing applications, biomedical imaging, etc.
