A small change in temperature causes a large change in resistance. It should tell me the thermistor is good, but maybe I need to do a more extensive test and compare the results with the offical temperature vs resistance chart. In any case, today I did the resistance test (put the thermistor into ice-cold water and tested the resistance), and it read 8.8K ohms. All the thermistors have 10,000 Ohms of resistance at 77°F or 25°C, but they vary greatly the further you get away from 77°F. They are used for resistance thermometers in temperature measurement and all Sterling Sensors assemblies are made using this type of thermistor. It is important to note that a thermistor’s change in resistance is non-linear. and are not used for temperature measurement.

Thermistor SENSOR SOLUTIONS 10K3A1 Series 1// 09/2015 Page 4 RESISTANCE V TEMPERATURE TABLE Temp. Positive temperature coefficient thermistors have a resistance which rises as the temperature increases (Fig 2.) The 1k thermistor heats up with 6mW, I don't know if that will influence the themperature. Commercially available thermistors have nominal values of 1K, 2K, 10K, 20K, 100K, etc. Thermistor Description Thermistor Overview BAPI Thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. It follows a pre-defined curve which is provided by the thermistor manufacturer. positive M - 2.2K3A1 Sensor type: Thermistor, temp coef. Thermistors are manufactured to follow a specific curve with a high degree of accuracy. At 32°F (0°C) the 10K-2 thermistor has 32,650 Ohms of resistance and a 10K-3 29,490 Ohms. The most common NTC thermistors are 10k and 100k ohms, where PTC are 470 ohms and 1k ohms. Alternate Energy Technologies (AET) is America's largest manufacturer of flat-plate, solar thermal collectors.We provide turnkey commercial solar water heating solutions as well as pre-engineered residential systems. NTC Thermistors for Temp. An NTC thermistor is a thermally sensitive resistor whose resistance exhibits a large, precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range. Figure 1: Thermistor resistance changes with temperature. As the temperature increases, the resistance first decreases, then rising slightly before it reaches a critical temperature, Tc. of ±0-2°C interchangeable thermistor.

Spec table for the GE-built refrigerators using the WR55X10025 thermistors. The other differences between the Thermistor and RTD are explained below in the comparison chart. In order to test you can measure the ambient temperature, make the sensor is removed and acclimated, measure the Ohms of resistance and compare to the manufacturer chart. negative P - 30K6A1 Sensor type: Thermistor, temp coef. : 9978155 - VAT Registered. C Ohms Temp. The Thermistor and the RTD both are the temperatures measuring device. The major problem NTC thermistor is the calibration, that is, to establish a function between electrical resistance and temperature. The major difference between the RTD and the Thermistor is that the RTD is made of metal, whereas the semiconductor material is used for Thermistor. The characteristic of the switching PTC thermistor shows that the device has a highly non-linear characteristic. To calculate the temperature you also need the specific numbers for that type of thermistor. %PDF-1.5 %���� A thermistor changes resistance based on the temperature it is exposed to. 3k 10kType 10kType 10kDale 10k3A210kG US 20k.
