Temperature Sensors - NTC Thermistors (Negative Temperature Coefficients) are used to control temperature precisely by providing a temperature-dependent output signal. The 112-104KAH-H01 is a temperature sensor used in a variety of applications. In this article, we will look at the application field and working principle of the 112-104KAH-H01.

The 112-104KAH-H01 is designed for applications where precise and accurate temperature measurement is required. It is used in many fields, such as cooling and heating systems, environmental monitoring, consumer electronics, automotive and medical application. The 112-104KAH-H01 sensor uses a semiconductor-based film integrated with a Thermistor, which consists of two main components. The first is a Thin Film Resistor (TFR) which acts as a temperature sensor, and the second is an NTC thermistor which acts as a temperature-dependent variable resistor.

The NTC thermistor is a temperature-dependent resistor which has a variable resistance across a certain range of temperatures. When the temperature of the NTC thermistor changes, its resistance will also change. This change in resistance is then used to measure the temperature. The NTC thermistor is connected to the TFR which produces an output voltage proportional to the temperature sensed by the thermistor.

The TFR is designed with multiple layers of metal-oxide film, which is deposited on an alumina substrate. Being temperature-dependent, the resistance of the metal-oxide-film-based TFR changes in response to the temperature changes. This allows the 112-104KAH-H01 to accurately sense and detect temperature changes over a wide temperature range and with high accuracy. The sensing range is between –20 to 85°C, and the standard tolerance is ±0.3°C.

The 112-104KAH-H01 sensor is supplied with a selection of standard PCB mounting packages and can be configured to meet the application requirements. It is recommended to use a surface mount technology to ensure better thermal contact. The surface mount can also reduce the number of wires, minimize sensitivity to external vibrations or shocks and improve the overall efficiency of the device.

The 112-104KAH-H01 also offers a wide range of optional features such as an emissivity-adjustable thermistor, temperature compensation for humidity and temperature to reduce measurement errors and a temperature-compensation facility to reduce the effects of temperature gradients in the device. The 112-104KAH-H01 also offers a variety of optional interfaces, such as RS232, I2C and CAN-bus.

In conclusion, the 112-104KAH-H01 is an accurate and reliable temperature sensor suitable for a range of applications. It has an excellent sensing range, precision and accuracy, and is suitable for use in high-temperature applications where precision control is required. The 112-104KAH-H01 is also available in several interface options and surface mount designs.
