Temperature Sensors - NTC Thermistors

Temperature sensors are devices that measure the temperature of an object. They detect, measure, and monitor the temperature of an area or component of a process. The most commonly used temperature sensors are thermistors, RTDs, thermocouples, thermometers, and infrared detectors. Among these types, NTC thermistors are widely used.A thermistor is a small electronic device made from semiconductor material. It is a type of temperature-sensing device that is sensitive to temperature changes. NTC thermistors, or negative temperature coefficient thermistors, have a decrease in resistance with an increase in temperature. BR42KB104M is a typical NTC thermistor with a 10K ohm nominal resistance at 25°C and a Beta of 4250K. This device has a wide temperature range between -50°C and 150°C and it is ideal for precision temperature sensing applications.The working principle of BR42KB104M is simple. When the temperature around the thermistor increases, the resistance decreases. This provides a signal for electronic sensing devices to detect and measure the temperature. This thermistor is made up of two components: a ceramic body in which the active material is embedded, and two external metal contacts. The device\'s ceramic body consists of a mixture of metal oxides, such as barium, strontium, and manganese. This mixture gives it a negative temperature coefficient.The temperature-dependent resistance of the BR42KB104M can be used to inform electronic devices when the temperature has exceeded a certain level. This device is used in a variety of temperature sensing applications, including HVAC systems, energy efficiency systems, industrial process controls, and security systems.In HVAC systems, the thermistor is used to control the operation of the thermostat. When the temperature rises above a certain level, it triggers the thermostat\'s signal so that the system can be turned on or off as needed. In energy efficiency systems, the thermistor helps regulate and monitor the temperature in order to maximize energy efficiency. It also plays an important role in industrial process control systems, as it is used to detect when temperatures have exceeded a predetermined level.The BR42KB104M thermistor can also be used in security systems, as it is able to detect when temperatures have exceeded a certain level. This can be used to detect intruders or fire, as temperatures in the monitored area will rise when a fire starts or when someone enters an area that is off limits. The BR42KB104M thermistor is an accurate and reliable temperature sensing device. Its wide temperature range and fast response time make it ideal for many temperature sensing applications. It is a cost-effective solution to many temperature sensing needs, and it is built to last.
