Temperature Sensors – NTC ThermistorsNTC thermistors are temperature-sensing devices that use a semiconductor material composed of oxides or metallic salts which exhibit large changes in electrical resistance as a function of temperature. Composed of positively and negatively charged particles, their main application is the measurement of temperature.The NHQ333B400T10 is a type of NTC thermistor which is typically used as a temperature sensing element. Noted for its small size and exceptional performance, it features an operational temperature range of -50 to 150 degrees Celsius with a nominal resistance of 10k ohms at 25 degrees Celsius.The temperature sensing element is composed of a ceramic disc with two ends, one marked with a green dot (which indicates the positive terminal) and the other with a red dot (indicating the negative terminal). The disc itself contains a specially formulated mixture of metallic oxides, specifically chosen based on their temperature coefficient, which determines the thermistor’s panel thermostat rating. The NHQ333B400T10’s working principles are based on the physical phenomenon known as the temperature-dependent resistance effect and thermionic emission effect. When the thermistor is exposed to an environmental temperature, the charge carriers within the ceramic disc become unsettled and begin to migrate in an effort to move to the area with the most energy. This increased movement of charge carriers causes the thermistor’s electrical resistance to decrease. This change in resistance can then be used to calculate the temperature using the equation: Resistance = Resistance (at 0°C) x e^(T/Beta).By utilizing these principles, the NHQ333B400T10 is able to provide long-term stable and accurate readings. It is most commonly used in applications that require temperature measurement, such as HVAC systems, refrigeration systems, incubators, automotive sensors, medical equipment, and industrial process control applications. The NHQ333B400T10 can also be used in robotics applications, where the measurement of temperature is essential to the operation of robots.In addition to temperature sensing, the NHQ333B400T10 is also used for over-temperature protection in ozone generators, high-end industrial machines and other computer-controlled equipment. This is due to the fact that thermistors are able to detect small changes in temperature and can respond quickly to fluctuations to provide effective protection from over-temperature conditions.The NHQ333B400T10 is designed to last long and remain reliable even after years of repeated temperature changes. It is also very inexpensive to produce, making it a highly cost-effective temperature sensing device for various applications.Overall, the NHQ333B400T10 is a highly reliable and versatile NTC thermistor that can provide accurate and stable temperature measurements for a variety of applications. It features a low cost, durable construction and is easy to use. This makes it an ideal choice for a range of temperature detection and protection systems.
