Temperature sensors are widely used in many applications. Generally, there are two categories of temperature sensors: analog and digital output. SA56004EDP,118 belongs to the analog temperature sensor. It can measure temperature between -40 and +125ºC.

The working principle of the SA56004EDP,118 is based on a thermistor. A thermistor is a temperature-sensitive device composed of a semiconductor material. Its resistance is directly proportional to the temperature. This means that as the temperature increases, the resistance of the thermistor decreases, and vice versa. The analog temperature sensor uses this relationship of temperature and resistance to measure temperature and output an analog voltage.

The analog temperature sensor is equipped with a bridge circuit. This bridge circuit consists of two resistors and two thermistors. The two thermistors are placed at opposite ends of the bridge circuit to form a bridge. When temperature changes, the resistance of each thermistor will change because of its temperature sensitive characteristic. As a result, this will cause an output voltage change on the bridge circuit. This output voltage is an analog output signal that is proportional to the temperature.

The features of SA56004EDP,118 allow it to be widely used in the industry and home applications. The accuracy and linearity tolerance are ± 2.0°C and 0.1°C respectively. The long-term degradation rate is 0.1°C and the operating current is 2.65 mA. The characteristics of this temperature sensor make it ideal for applications that need precise temperature measurements. It is commonly used in refrigeration systems, air quality control systems, environmental monitoring systems and medical equipment, among other applications. It also has wide range temperature measurement from -40°C to +125°C.

The SA56004EDP,118 analog temperature sensor is a reliable and robust device with wide applications in various industries. It has a linear output, high accuracy, and high resolution. It is also cost-effective and easy to use, making it an ideal choice for various temperature-sensing applications.
