OEM Medical Temperature Sensor Has Good Insulation Sealing And Mechanical Impact Resistance

NTC temperature sensors are usually composed of 2 or 3 metal oxides, mixed in a fluid-like clay, and calcined into a dense sintered ceramic in a high-temperature furnace. Oxygen-bonded metals tend to donate free electrons. Ceramics are generally excellent insulators. But only theoretically, this is the case for thermistor-type ceramics when the temperature approaches absolute zero. However, as the temperature increases to more common ranges, thermal excitations eject more and more free electrons. As more electrons carry current through the ceramic, the effective resistance decreases. Resistance changes very sensitively with temperature. A typical change is a decrease of (-)7[%] to 3[%] per degree Celsius. This is the most sensitive of any sensor suitable for use over a wide temperature range.

The main technical parameters:

1. The rated zero-power resistance value R25 refers to the zero-power resistance value of the thermistor measured at 25°C.

2. B value; defined as the ratio of the difference of the natural logarithm of the zero-power resistance value at two temperatures to the difference between the two temperatures.

3. Thermal time constant; under zero power conditions, when the temperature changes suddenly, the time required for the temperature of the thermistor body to change by 63.2% of the temperature difference between the beginning and the end.

4. Dissipation coefficient; at a specified ambient temperature, the ratio of the change in power dissipation of the thermistor to its corresponding temperature change.

Working principle of temperature sensor

Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
