Abstract | Electromagnetic interference (EMI) disturbs significantly thermal diffusivity measurements by laser flash method. This paper presented a progress in suppressing EMI by developing a new amplifier, programming a new software of digital filters, promoting the stability of furnace and applying a high performance data acquisition card. A armco iron sample whose thickness is 2.88mm was measured once again, the repeatability was observed to be improved from the previous 1%-3% into the present less than 8‰. |
