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, itp.
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 to powszechnie stosowany cyfrowy czujnik temperatury. It outputs digital signals, has the characteristics of small size, niskie obciążenie sprzętowe, silna zdolność przeciwzakłóceniowa, wysoka precyzja, 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 Drut, and through 64-bit identity authentication, the temperature information collected from different sensors can be read separately.
Wysoka dokładność i precyzja NTC termistorów są stosowane w różnych branżach, Od zastosowań medycznych po przemysł. Przemysł medyczny opiera się na NTC w różnych zastosowaniach, w tym cewnikach, sprzęt do dializy, i monitorowanie pacjentów. Ta część czujnika medycznego jest 1355 Ohmy w 37 ° C z beta 25/85 z 3976.
Metal thermal resistors such as nickel, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platinum has the most stable physical and chemical properties and is the most widely used. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. Ponadto, the temperature measurement ranges of Pt500, PT1000, itp. są kolejno zmniejszone. PT1000, temperature measurement range -200～420 ℃. Według międzynarodowego standardu IEC751, Charakterystyka temperatury rezystora platyny PT1000 spełnia następujące wymagania:
