Temperature Sensors - NTC Thermistors

Temperature sensors are among the most frequently used technologies in the HVAC industry. A key type of temperature sensor is an NTC thermistor, which is used to measure temperature changes over a wide range of temperatures. The NHQM152B345T5 is one such NTC thermistor and this article will discuss its application field and working principle.NTC thermistors are composed of a semi-conductor material such as metal oxides, which respond to changes in temperature. The NHQM152B345T5 is a negative temperature coefficient (NTC) thermistor, which means that it experiences a decrease in electrical resistance as the temperature increases. This characteristic of NTC thermistors makes them ideal for measuring changes in temperature over a wide range, from about -40°C to +105°C.The NHQM152B345T5 NTC thermistor can be used in a variety of applications. One common use for this type of thermistor is in a heating, ventilation, and air conditioning (HVAC) system. It can be used to measure and control the temperature of the air inside the building, as well as the temperature of the outdoor ambient air. In addition to HVAC systems, the NHQM152B345T5 thermistor can also be used in smoke detectors, medical equipment, and other applications that require precise temperature control.The working principle of the NHQM152B345T5 thermistor is relatively simple. The device is composed of two leads, one of which is connected to a resistor. When exposed to a temperature change, the resistance changes, which is then measured by the connected device. This resistance change is proportional to the temperature change. As the temperature rises, the resistance of the resistor decreases, and vice versa.In order to maximize its performance, the NHQM152B345T5 should be properly mounted in the application it is being used in. The device should be mounted on a flat, thermally conductive surface. This will ensure that the thermistor will be affected by any changes in temperature directly, without being affected by differences in air flow or other external factors. Proper installation will ensure that the thermistor will measure accurate temperatures.In summary, the NHQM152B345T5 is a negative temperature coefficient (NTC) thermistor used to measure temperature changes across a wide range of temperatures from -40°C to +105°C. This device can be used in a variety of applications, such as HVAC systems, smoke detectors, and medical equipment. Its working principle is relatively simple, with the resistance changing in response to temperature changes. Properly mounting the device will ensure optimal performance and accurate temperature readings.
