EXSENSE high-accuracy NTC thermistor, as sensitive component which resistance value decreases nonlinearly with rising temperature, plays a core role in temperature signal acquisition in electronic thermometer. From the perspective of electronic thermometer functionality, it needs to measure human body temperature accurately and quickly to provide reliable data for medical diagnosis. Utilizing the fast-response of NTC thermistor can help better capture body temperature changes and achieve real-time temperature monitoring.
In the design of electronic thermometer, NTC thermistor is usually installed at the front of the probe, which directly contacts or is close to the measurement site of the human body, ensuring that the NTC captures temperature changes in a shorter time. When the electronic thermometer operates, the resistance value of the EXSENSE thermistor changes with body temperature. This data is converted into a voltage signal through a voltage divider circuit and then undergoes analog-to-digital conversion by the ADC module. Afterward, the microprocessor calculates the corresponding temperature value and eventually displays it to the user on the screen. To ensure a stable and fast measurement process, EXSENSE Electronics recommends using EXSENSE miniature insulated lead NTC thermistor, which offer:
1. High Accuracy
As one of the important physiological indicators, accurate body temperature measurement is directly related to medical personnel’s diagnosis. EXSENSE thermistor can achieve an accuracy of ±0.5%, assisting electronic thermometer in capturing subtle body temperature fluctuations and providing precise data support.
2. Fast Response
The temperature-sensing head of EXSENSE miniature NTC thermistor is small (diameter can reach 1.2mm), significantly reducing the time cost of measuring body temperature. Compared to traditional mercury thermometer, which require at least 3 to 5 minutes to stabilize the reading, the rapid response of NTC thermistor improves the convenience usability of electronic thermometer, especially suitable for scenarios requiring quick temperature measurements, such as children or emergency.
With its excellent electrical characteristics, EXSENSE miniature insulated lead NTC thermistor effectively reduces the probability of misdiagnosis or delayed treatment during medical temperature measurement. EXSENSE miniature insulated lead NTC thermistor functions like a fast-response "temperature-sensing heart" for electronic thermometer, ensuring no delay from skin contact to signal output and truly achieving both "high efficiency and accuracy" and "convenient experience" in medical temperature measurement scenarios.
