Temperature Sensors - NTC Thermistors generally consist of a negative temperature coefficient (NTC) thermistor that measures temperature changes using the property of electrical resistance decreasing when temperature increases. The Model 112-103FAF-B01 is one such device. This application note will discuss the field of application and working principle of this model.

Principle of Operation

The Model 112-103FAF-B01 consists of a tiny NTC thermistor disc, protected by a plastic case and a specially designed thermally insulated mounting sleeve. It is a precision bond, having a precisely determined thermistor resistance at each specific temperature and temperature coefficient. At any given temperature, the thermistor resistance has a predictable relationship to the circuit resistance to which it is connected. As a result, changes in temperature are indicated by a corresponding change in the thermistor resistance.

To use the Model 112-103FAF-B01, it should be mounted in the device that is to be monitored. The small thermistor leads have very low mass and will respond rapidly to temperature changes. The thermistor shows a negative temperature coefficient (NTC) characteristic. This means that when the ambient temperature increases, the thermistor resistance also increases, while inversely, a decrease in temperature results in a decrease in thermistor resistance.

Range of Application

The Model 112-103FAF-B01 is applicable for a wide range of temperature measurement. Due to the small size and fast response, this thermistor is highly suitable for precision temperature measurements in environments where temperatures change rapidly. The operational range of the 112-103FAF-B01 starts at -40°C and goes up to +150°C.

With its small size, the 112-103FAF-B01 is particularly suitable for use in compact areas or for automation systems which take up as little space as possible. The thermistor offers excellent accuracy along with rapid and reliable temperature sensing. The device is also very durable and provides a long lifespan, even in harsh environments.

In conclusion, the Model 112-103FAF-B01 is an excellent choice for temperature sensing in extreme situations. With its small size and fast response, as well as its excellent accuracy and durability, it makes an ideal choice for any application requiring precise temperature sensing.
