Thermistor Resistance Vs Temperature Chart

Thermistor Resistance Vs Temperature Chart - The heat dissipation constant is an expression in milliwatts of the power required to raise the temperature of a thermistor 1°c above the ambient. Temperatures in multiples of ten can be found down the left axis, whilst for more precise readings you must move along the horizontal axis between one and nine. Negative temperature coefficient (ntc) thermistors have a resistance which reduces as the temperature rises (fig 1.). Web thermistor resistance vs temperature chart. Web ntc temperature thermistors have a negative electrical resistance versus temperature (r/t) relationship. Only thermistors with ±0.2°c interchangeability are available encased in teflon as standard parts. Data in white refers to thermistors with ±0.2°c interchangeability. Web 10,000 ω type 3, ntc thermistor, greystone sensor codes 07 & 40 note: Of teflon encased thermistors add 100 to part no. This makes them ideal for accurate temperature measurement and control.

Web the resistance temperature curve defines the temperature versus resistance characteristics, some curves change faster (steep slope), while others change more slowly (weaker slope). Of teflon encased thermistors add 100 to part no. Web ntc temperature thermistors have a negative electrical resistance versus temperature (r/t) relationship.

Web The Following Is A Table Of The Correlation Between The Temperature And The Resistance For The Thermistor Used In Many Pasco Products.

Web thermistor resistance vs temperature chart. Web calculate the resistance in ohms of resistors connected in series by entering the value of each. Web the chart below can be used as a referencing tool to find the relationship between a range of temperatures and resistance for pt100 rtd sensors.

Both Tables Contain The Same Information.

Web the resistance of the thermistor will change according to temperature, and should track with the following table. Web temperature / resistance chart 10,000 ω @ 77 °f temp °f ohms temp °f ohms temp °f ohms temp °f ohms 0 85,378 33 31,738 66 13,138 99 5,961 1 82,710 34 30,855 67 12,811 100 5,827 2 80,135 35 30,000 68 12,493 101 5,697 3 77,649 36 29,171 69 12,184 102 5,570 4 75,249 37 28,376 70 11,883 103 5,446 5 72,931 38 27,589 71 11,591 104. The precon sensor has a dissipation constant in still air at 25°c of 2.7 mw/°c. Higher temperature applications generally use the higher resistance thermistors (above 10,000 ω) to optimize the resistance change per degree at the required temperature.

Sensor Tolerance Is ±0.2°C In The Range 0 To 70°C.

Temperature/resistance figures are the same for both types. Temperatures in multiples of ten can be found down the left axis, whilst for more precise readings you must move along the horizontal axis between one and nine. ±0.15°c @ 0°c (±0.28°f @ 32°f). In the typical control range (0°c to 40°c), 10k thermistors offer good sensitivity
