Temperature Sensors - NTC Thermistors have been used for many years in industrial and consumer applications. EC95R102W is one of the most important components in the temperature sensing field and it is widely used for measuring temperature in various applications. This article will discuss the application field of the EC95R102W and its working principle.

Application Field

The EC95R102W NTC Thermistor is typically used to measure temperatures in the range of -50°C to +150°C and can also be used to measure temperatures up to +200°C. The operating Voltage range for the EC95R102W is normally 4.5V to 50V. It is usually found in the automotive, domestic appliance, heating/ventilation/air conditioning, HVAC, medical, home/building automation, industrial, agricultural, consumer, and transport applications.

The EC95R102W is particularly suitable for measuring temperatures in harsh environments because of its relatively high accuracy and stability Figure 1. It can operate in a wide range of temperature, humidity, and vibration conditions. Furthermore, the EC95R102W provides excellent long-term stability even in extreme ambient conditions.

Working Principle

The EC95R102W is an NTC Thermistor, which works by measuring the resistance of a temperature-sensitive material in response to changes in temperature. The material is usually a ceramic with a metallic oxides such as cobalt, chromium, manganese and nickel. NTC Thermistors are very sensitive to even small changes in temperature and have a high output voltage. The EC95R102W is constructed from a thermistor material and two terminal pins are used for its operating connection.

When the EC95R102W is connected to a power source, the thermistor material acts as a resistor, and the voltage across it is determined by the current flowing through it. As the temperature changes, the resistance of the thermistor material changes as well. This changes the voltage across the thermistor and this variation in voltage is proportional to the change in temperature. Therefore, by measuring the voltage at the terminals we can accurately measure the temperature.

On the other hand, the EC95R102W is also used as a temperature switch, which turns a circuit ON/OFF when the measured temperature reaches a certain set point. When the measured temperature exceeds the set point, the resistance of the thermistor increases, which in turn switches the circuit OFF. This is the temperature switch function of the EC95R102W.

The EC95R102W is also ideal for use in other applications such as temperature control systems, temperature sensors, temperature limiters, and temperature correction systems. The advantages of using the EC95R102W include its low cost, small size, long life, and excellent stability.

In conclusion, the EC95R102W NTC Thermistor is a critical component in temperature sensing systems. It is used to measure temperatures in the range of -50°C to +150°C, and can also be used in applications up to +200°C. Its working principle is based on the resistance change of a temperature-sensitive material, which is used to accurately measure the temperature or switch a circuit on/off when the temperature has reached a predetermined set point.
