Disposable medical application temperature sensors, ablation application sensors, and forehead temperature gun application sensors.
NTC thermistor is a kind of heat-sensitive semiconductor resistor, whose resistance value decreases with the increase of temperature, and the TCR is about 10 times of the metal TCR, the change of resistance value of NTC thermistor can be caused by the change of external environment temperature, and also can be caused by the current flow and its own heat.
Temperature sensors for ablation applications mainly use thermocouple resistance
Thermocouples work by joining two different metals to form a sensing junction. When the temperature of the sensing junction differs from that of the free end, the thermocouple will generate a voltage between the two wires. The voltage signal can be converted to a temperature reading.
Forehead temperature gun, ear temperature gun application sensor mainly uses the thermopile technology
Thermopile probe infrared thermometer, is by measuring the radiation energy emitted by the object, according to Boltzmann's law, the greater the radiation energy, the higher the temperature of the object, the infrared radiation signal into electrical signals, and then through the amplifier and signal processing circuit, and according to a certain algorithm and the target emissivity correction, the final can be transformed into the temperature value of the target to be measured.
