【 摘 要 】

The SSPX Thermistor is a glass encapsulated bead thermistor made by Thermometrics, a BR 14 P A 103 J. The BR means ruggedized bead structure, 14 is the nominal bead diameter in mils, P refers to opposite end leads, A is the material system code letter, 103 refers to its 10 k{Omega} zero-power resistance at 25 C, and the tolerance letter J indicates {+-} 5% at 25 C. It is football shaped, with height ->, and is viewed through a slot of height h = 0.01 inches. The slot is perpendicular to the long axis of the bead, and is a distance s {approx} 0.775 cm in front of the thermistor. So plasma is viewed over a large angle along the slot, but over a small angle {alpha} perpendicular to the slot. The angle {alpha} is given by 2s tan{alpha} = -> + h.
