Temperature sensors that use positive temperature coefficient thermistors (PTC) are robust and versatile and have many applications in different areas. The PTCSL40T081DBE is a thermistor designed to detect temperature changes and control them. This article will discuss the application field and working principle of the PTCSL40T081DBE temperature sensor.

Application field

The PTCSL40T081DBE thermistor is designed for applications such as general temperature sensing, over-temperature detection, and thermal protection. This thermistor has an operating temperature range of -50 to +150 °C and can detect thermal changes in a wide variety of environments. It is used extensively in air conditioning systems, refrigeration systems, and automotive cooling systems. Additionally, because the PTCSL40T081DBE itself is RoHS compliant, it can be used in green applications such as solar energy systems and wind energy systems.

Working Principle

The PTCSL40T081DBE is a two-wire thermistor that works using the principle of Positive Temperature Coefficient (PTC). This means that the resistance of the device increases as the temperature rises. This increase in resistance then triggers an electrical imbalance in the circuit in which it is placed, which can be used to detect changes in temperature. This thermistor is designed to detect temperature changes in the range of -50 to +150 °C, meaning it can be used for both low-temperature and high-temperature applications.

The PTCSL40T081DBE thermistor works using a two-wire connection. One wire is connected to the thermistor itself, and the other wire is connected to the power source. When an external stimulus such as temperature change is present, the resistance of the thermistor increases. This increase in resistance triggers an imbalance in the circuit, which can be detected and used to measure the temperature.

The PTCSL40T081DBE is a robust and reliable temperature sensor that is used in a variety of applications. It has an operating temperature range of -50 to +150 °C and can be used for both low temperatures and high temperatures. Additionally, since the thermistor is RoHS compliant, it can be used in more environmentally friendly applications. With its versatile design and reliable performance, the PTCSL40T081DBE is a great choice for temperature sensing and control applications.
