Pipe Profiling Sonar - 1512 USB Specification

The resolution and update speed of the Model 1512 Pipe Profiling Sonar is second to none in the field of mechanically scanned sonars. The 2MHz acoustic signal is amplified and logarithmically compressed prior to being digitised by a Flash A/D converter. The angular resolution of the system is 0.9 which gives 400 sectors per revolution. For each sector the data is oversampled and peak detected toarrive at 250 range cells. The digitally generated graphics display uses 256 colours to represent the signal amplitude. At a minimum full-scale range of 125mm this gives a range resolution of 0.5mm and at 3m range the resolution is 12mm.

The acoustic beamwidth of 1.1 ensures that the finest detail from the pipe surface is recorded. Pitch and Roll sensors inside the scanner record the attitude of the sonar to a resolution of 0.1. The sonar has been engineered for extended operations in hostile environments. The transducer and drive motor are totally enclosed in an oil-filled pressure balanced housing which is hermetically sealed from the stainless steel electronics pod. The system has many applications other than inside pipes where short range high precision measurements are required with a rapid screen update.
