① ② ③ ④ ⑤
①MF ¬ - negative temperature coefficient (NTC) thermistor code.
② 53 - with a variety of NTC thermistor with case temperature sensor.
③103 - thermistor nominal resistance, said the resistance of the nominal resistance: 10 × 103 (Ω).
F = ± 1%, G = ± 2%, H = ± 3%, J = ± 5% of the resistance value (accuracy)
⑤ 3950 - resistance of the thermal index (material coefficient) B value: 395 × 10 (K)
Note: According to customer requirements,Provide different R value, B value accuracy, customization.
When measuring NTC thermistors, the following must be observed:
• Can not be measured in air, The temperature difference in the air is bigger, Measurement is not accurate, Resulting in accuracy bias.
• Measurement using a high-precision thermostat, NTC into the thermostat after the test tank, After the temperature of the thermostat is stable, Can be measured.
• Measure voltage as low as possible,To reduce NTC self-heating caused by measurement error.
• For high temperature measurements,The temperature of the bath needs to be corrected and checked with a thermometer.
