Week 2

Hi everyone,

The new technology that I will be using for analyzing large ferrous particles in hydraulic fluids arrived last week and the new technology is the Lasernet Fines Q230. The Q230 consists of a particle imaging system which counts particles >4µm (microns) in a fluid and a dual magnetometer system that counts ferrous articles >25 microns and the total concentration of ferrous particles in parts-per-million (ppm). I will be focused on the dual magnetometer system of the Q230 because this is the new technology that can give a quantitative result of ferrous particles in a given hydraulic fluid. Before testing we had to make sure the Q230 was functioning properly by calibrating it with the given calibration fluids provided. The Q230 is functioning properly when the given calibration fluids are tested on it and yield a certain result. After configuring the Q230 to the computer we stared to calibrate it and after a couple of hours the Q230 yielded the proper results of the calibration fluids and worked properly. I also read the Q230 instruction manual before I started conducting tests on it and gave a status report. This week I also prepared reference samples by creating a concentrated 250mL bottle filled with 18.56mg of ISO medium test dust and 200mL of MIL-PRF-5606 hydraulic oil (sample will be called test dust concentrate). Next I filled separate 250mL bottles (reference samples) with different amounts of test dust concentrate and tested them on the Q230.
