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.

The sensing element this SPRT is sealed inside an Inconel

sheath

to ensure the best stability and repeatability. The seal can be

breached if the SPRT is over heated for an extended period of

time.
