Vcc ) R (Ry// Rx Ry//R Vcc 0.72 TL TH × + = RTL= The resistance of thermistor at lower limit of temperature protection. Substitution and rearranging the equations yields Rx= 2.061 TH TL TH TL R R R R − × × Ry = TH TL TH TL 6.3R R R R 5.3 − × × If the temperature characteristic of the thermistor is like that of the SEMITEC 103AT-2, the resis- tance of Rx and Ry is tabulated below for different values of TL and TH: (note: TL is the lower temperature limit and TH is the upper temperature limit.) 56 8.1 86.5 57 7.8 75.0 58 7.5 66.0 59 7.2 58.7 60 7.0 52.8 61 6.8 47.8 62 6.5 43.6 63 6.3 39.9 64 6.1 36.8 65 5.9 34.0 66 5.7 31.6 67 5.5 29.5 68 5.3 27.5 69 5.2 25.8 70 5.0 24.3 TABLE 3 Values of Rx and Ry at TL = 0°C TH ( °C) Rx(k Ω) Ry (k Ω) 50 10.1 551.1 51 9.7 300.7 52 9.4 204.8 53 9.0 153.9 54 8.7 122.8 55 8.4 101.8 TABLE 4 Values of Rx and Ry at TL = -10°C TH ( °C) Rx (k Ω) Ry (k Ω) 45 11.4 95.6 46 11.0 85.0 47 10.6 76.2 48 10.2 68.9 49 9.8 62.8 50 9.5 57.5 51 9.1 52.9 52 8.8 48.8 53 8.5 45.3 54 8.2 42.1 55 7.9 39.4 56 7.6 36.8 57 7.4 34.6 58 7.1 32.5 59 6.9 30.7 60 6.7 29.0 61 6.4 27.4 62 6.2 26.0 63 6.0 24.6 64 5.8 23.4 65 5.6 22.2 |
