When faced with thousands of NTC thermistor types, choosing the right one can be quite overwhelming. In this technical article, I will walk you through some of the important parameters to keep in mind when selecting a thermistor. This is especially true when deciding between the two common types of thermistors used for temperature sensing: negative temperature coefficient NTC thermistors or silicon-based linear thermistors.
Commonly used NTC thermistors for air conditioner
There are three types: indoor ambient temperature NTC, indoor coil NTC, and outdoor coil NTC. Higher-end air conditioners also use external ambient temperature NTC, compressor suction and exhaust NTC, 等.
How does the car reflect the temperature of the car engine coolant? It is through the water temperature sensor, which is also called the water temperature sensor plug. So where is the specific location of the car water temperature sensor? The water temperature sensor enables the control unit to identify engine overheating or an unusual rise in temperature. How much does a car water temperature sensor cost?
DS18B20 is a commonly used digital temperature sensor. It outputs digital signals, has the characteristics of small size, low hardware overhead, 抗干擾能力強, 高精度, and is widely used.
DS18B20 is a digital temperature sensor that uses a single bus timing to communicate with the host. Only 1 Wire is needed to complete the temperature data reading;
DS18B20 has a built-in 64-bit product serial number for easy identification. Multiple DS18B20 sensors can be connected to 1 線, and through 64-bit identity authentication, the temperature information collected from different sensors can be read separately.
High Accuracy and Precision NTC thermistors Sensors are used in various industries, from medical to industrial applications. The medical industry relies on NTC’s in various applications including catheters, dialysis equipment, and patient monitoring. This medical sensor part is 1355 Ohms at 37°C with Beta 25/85 之 3976.
鎳等金屬熱電阻器, 銅和鉑電阻器與電阻隨溫度的變化呈正相關. 鉑具有最穩定的物理化學性質，應用最廣泛. 常用鉑電阻Pt100的測溫範圍為-200~850°C. 另外, Pt500嘅溫度測量範圍, 鉑1000, 等. 依次減少. 鉑1000, 溫度測量範圍- 200~420°C. 根據IEC751國際標準, 鉑電阻Pt1000嘅溫度特性滿足以下要求:
