Based on the time tested DPV-2000 technology, Tecnar Automation is proud to introduce AccuraSpray and Watson Grinding is proud to own and use Tecnar's latest version, a sensor specifically designed for industrial online monitoring of thermal spray processes. Five years of field experience with the DPV-2000 has led to the development of a simpler, cheaper and tougher instrument adapted to the requirements of production environments. AccuraSpray allows process-independent control of coating properties by providing precise, reliable, real time measurements of the average particle temperature, velocity and flow rate as well as the vertical position and profile of the plume itself. Values of these parameters are continuously recorded, displayed and compared, on screen, against user adjustable tolerances.

| DPV-2000 users all over the world have known for quite a while that the reproducibility of coatings obtained by spraying processes strongly depends on the ability to monitor and control key variables of the process. AccuraSpray now brings this functionality to the shop floor. Test pieces and wasted production can be reduced and even eliminated entirely. Improved process control also leads to better forecasting of the coating thickness. Process-independent coating specifications based on particle properties can be developed. Electrodes and other torch consumables can be replaced only when necessary, not blindly based on the shortest life expectancy. Electrode life can even be extended by compensating small amounts of wear with slight adjustments of process parameters to bring back particle properties within specified tolerances. The AccuraSpray is based on a proprietary Windows 32-bits operating software that works in conjunction with the instrument's custom optics and electronics to deliver real time, high precision data. The collected data is statistically analyzed, recorded and displayed in different forms. |

| Please also note that the Accuraspray has been successfully used for the characterization of various materials deposited by either SPS (Suspension Plasma Spraying) or S-HVOF-S (Suspension HVOF Spraying). |
