Temperature Sensors - NTC Thermistors

Thermistors are a type of temperature sensor used to measure temperature and are capable of detecting and measuring slight changes in temperature. This article will look at the application field and working principle of one such thermistor device: the 1DE104K-EC and provide an overview of the device\'s features and capabilities.The 1DE104K-EC is a thermistor device designed for use in HVAC, automotive, industrial and other environments where precise temperature measurements are necessary. The device is a negative temperature coefficient (NTC) type thermistor, meaning that its resistance decreases as temperature increases. The 1DE104K-EC is a two-wire device, requiring only a power source and a return leg to operate. The thermistor is implemented in a small, compact form factor and requires only minimal installation.The thermistor is constructed from a ceramic disk with a built-in resistor bridge (made up of four resistors) which is then sealed with a waterproof epoxy to prevent environmental exposure or corrosion. The thermistor is connected in a voltage divider fashion, where the voltage across it is proportional to the temperature. The thermistor can measure temperatures from -50°C to +250°C and can detect a change in temperature as small as 0.2°C.The thermistor also has a number of other design features that enable it to increase accuracy and durability in challenging environments. It has a tight thermal time constant (less than 2 seconds) and can operate in temperatures up to 160°C. The thermistor can also be set to measure the air temperature, as well as the surface temperature, and its accuracy is maintained even when subjected to shock and vibration environments.In operation, the thermistor is connected in a voltage divider configuration, with the nominal resistance at 0°C being 10KOhm. The value of the resistance decreases as the temperature increases, causing a corresponding increase in the voltage across the thermistor. The voltage is then measured by an ADC and converted into a temperature signal.The 1DE104K-EC thermistor is a reliable and accurate temperature sensor designed for use in a variety of applications. Its tight thermal time constant ensures fast and accurate response times and its small size and minimal installation make it ideal for applications where space is limited. Additionally, its waterproof design makes it suitable for outdoor and other harsh environment installations.
