TLA (Thin Layer Activation) is our key product. The method allows performing on-line wear measurements on running engines without dismantling parts (i.e. camshafts, cylinder sleeves, piston rings, valves & seats, bearings, turbocharger bearings, etc.). TLA is also convenient for studying the impact of lubricant formulation, fuel dilution and soot content on wear --> Technical brochure
DSi provides TLA-RNT measurement services as a full package that includes activation services, equipment sales & renting and qualified manpower. Wear measurements services can be performed either at your site or at our engine test centre in Belgium.
A particle accelerator is used to produce a thin layer of radiotracers at the surface of wear parts.
On-line wear measurement : "direct" and "flow-through" methods
A probe is installed externally to the engine for monitoring of the gamma-ray signal emitted by the labelled area. Any loss of signal is automatically converted in material loss.
Also known as “flow through method”, it consists in monitoring the increase of gamma-ray signal in the lubricant where worn particles are released. A probe is installed in a measuring chamber where the fluid is circulated. A particle trap (a filter or a magnet) can also be installed in the chamber to collect worn particles.
