3.5 Thermal EMF
Each AccuMac PRT has gone through an annealing process and
stability test to minimize the thermal EMF, which is caused by either
impurities of sensing element or temperature differentials at lead wires
connection point.
3.6 Over Heating
The sensing element of AM1660 PRT is sealed inside an Inconel
tm
sheath to ensure the best stability and repeatability. The seal can be
breached if the PRT is over heated for an extended period of time.
