Temperature Sensors – NTC Thermistors

NTC thermistors, or Negative Temperature Coefficient Thermistors, are a type of temperature sensor commonly used for temperature measurement in a wide range of applications. The TH238J34GBSN model is a high-performance NTC thermistor suitable for a variety of environmental monitoring, medical, or industrial settings. This article will discuss the working principle of the TH238J34GBSN thermistor and its potential application fields. NTC thermistors, as their name suggests, exhibit a negative temperature coefficient of resistance. This means that the resistance of the thermistor decreases with increasing temperature; for every 10 degree increase in temperature, the resistance of the thermistor typically decreases by approximately 3%. In contrast, conventional resistors show a positive temperature coefficient, meaning their resistance increases with rising temperatures. The TH238J34GBSN thermistor is a highly accurate and robust temperature sensor with a wide use temperature range from -40°C to 125°C, allowing it to measure extreme temperatures as well as more moderate environments. It has a semiconductor body of silver oxide which, along with its small size, gives it excellent utilization in space-limited areas. The TH238J34GBSN thermistor also features a high resistance accuracy of ±3% at 25°C and ±20% from -40°C to 125°C, allowing it to measure a wide dynamic range of temperatures with consistency and accuracy. The working principle of the TH238J34GBSN thermistor is relatively simple. The thermistor consists of semiconductor material, usually containing oxides of metals such as aluminum, nickel, and copper. The semiconductor material is constructed in a specific configuration, with a curving wire wound around it. When the temperature increases, the semiconductor expands and causes the resistance to decrease, and when the temperature decreases, the semiconductor contracts and causes the resistance to increase. If a voltage is applied to the thermistor, it will produce a current inversely proportional to the resistance; as the resistance decreases, the current increases. Given the TH238J34GBSN thermistor’s specifications, it is suitable for a range of applications. It can be used in medical instruments such as pulse oximeters and in industrial and agricultural settings. It can be even used to measure temperature in vehicles or home appliances such as refrigerators and air conditioners. The TH238J34GBSN thermistor is also remarkably versatile when it comes to testing for temperature changes, since its range of accuracy can measure large changes in temperature without compromising accuracy. The TH238J34GBSN thermistor is an extremely robust and versatile temperature sensor suitable for use in a variety of environments and settings. Its working principle of decreasing resistance for increasing temperature allows it to measure a wide range of temperatures with accuracy and consistency. Given its excellent specifications, the TH238J34GBSN thermistor can be suitable for applications such as medical instruments, industrial and agricultural settings, and domestic appliances.
