The PMI (positive material identification) test proves which alloy constituents exist in a material. There are various common test procedures:
* With spectrographic analysis an arc is generated between the thermowell surface and the test equipment. The spectrum of this arc enables the alloy’s elements to be identified both qualitatively and quantitatively. This process does leave a characteristic burn mark on the work piece.
* A test procedure that does not damage the surface is X-ray analysis, during the X-ray period the atoms of the thermowell material are energised until they radiate. The wavelength and intensity of the emitted radiation is again a measure of the alloy’s constituent elements and their concentrations.
WIKA South Africa has purchased an XRF (X-ray fluorescence) analyser to perform PMI testing, both incoming raw material, as well as for PMI certificates on outgoing finished goods.
