NTC thermistors (Negative Temperature Coefficient) are temperature sensors commonly used for a variety of industrial applications, such as temperature measurement, temperature protection, temperature compensation, and over-temperature protection. This article will discuss the RL2004-26K-155-D1 thermistor and its application field and working principle.

The RL2004-26K-155-D1 thermistor is a negative temperature coefficient (NTC) thermistor with a resistance value of 26K ohms at 25°C. It is composed of a ceramic body with a pair of metalized electrodes on opposing sides of the body. The ceramic body is sealed with a protective epoxy coating, which makes the thermistor highly resistant to moisture and environments. It offers high accuracy and excellent linearity and reliability, and has a fast response time. This thermistor also has a wide operating temperature range of -40°C to +130°C.

The RL2004-26K-155-D1 thermistor is suitable for various indoor and outdoor applications, including air conditioning systems, refrigerators, temperature measurement instruments, medical equipment, etc. It can be used to detect temperature changes, monitor temperature, and protect against over-heating. In addition, the thermistor can also be used to detect and compensate for temperature variations in electronic circuits, as well as to provide protection for a variety of electrical components.

The working principle of the RL2004-26K-155-D1 thermistor is based on the fact that the resistance of a thermistor changes with temperature. In simple terms, as the external temperature rises, the resistance of the thermistor decreases and vice versa. The change in resistance can be measured and used to calculate the temperature of the environment. This thermistor follows the classic voltage divider circuit, in which a fixed resistor is connected in series with the thermistor, and the voltage drop across them is measured. The voltage drop is then converted into a temperature value using a mathematical formula.

In conclusion, the RL2004-26K-155-D1 thermistor is a highly accurate NTC temperature sensor suitable for indoor and outdoor applications. It has a wide operating temperature range and high reliability, and the working principle is based on the fact that the resistance of the thermistor changes with temperature. This thermistor provides temperature measurement, temperature protection, temperature compensation, and over-temperature protection for a wide variety of industrial applications.
