MsS(magnetostrictive sensor) System

The MsS System is a device that electromagnetically generates and receives low-frequency ultrasonic guided waves. It is used for rapidly surveying a long length of pipeline from a single test location. The corrosion wall loss and cracks in aboveground, buried, and insulated pipe can be detected, and their locations and sizes can be estimated by analyzing the data with user-friendly software. The MsS system is also useful for inspecting and monitoring areas that are difficult to access, such as those at high elevations, behind walls, or under insulation, from a remote accessible location. This saves the time and money that would otherwise be used for scaffolding, insulation removal, or excavation.

The MsS System is composed of MsSR3030 instrument, MsS probes, and a laptop computer as shown in a schematic diagram. The operating software in laptop computer controls operating parameters of MssR3030 and acquires data through a USB port. The MsSR3030 instrument generates tone-burst electric pulse to MsS probes and detects induced voltage in MsS probe that is generated when the ultrasonic guided wave passes through the probe. The signal received from both directions of pipe are analyzed and reported with data analysis and reporting software.

The MsS System was developed at Southwest Research Institute^® (SwRI^®) and is manufactured at SwRI^® located San Antonio, Texas by SwRI^® personnel to ensure high quality instrumentation.
