The sensing component of Surface Temperature Sensor is NTC thermistor. It is sealed with an empty metal container. When it touches to object need to be measured, it has very quick response.
NTC thermistor consists of manganese, cobalt, nickel and copper. It is manufactured by ceramics. All those metallic oxide are semiconductors because they are same as germanium and silicon in conducting modes. When the temperature is low, the quantity of carrier on those materials is low. Thus, its resistance is high. When temperature rises up, quantity of carrier increases and resistance drops. NTC thermistor can be widely used to measure, compensate temperature and restrain surge current.
Specification
| Range | -30ºC~135ºC |
| Accuracy | ±0.8 ºC(0-100ºC) |
| Resolution | 0.1ºC |
Usage
Connect the probe to Surface Temperature Sensor and connect Surface Temperature Sensor to any port in SenseDisc.
Keep the probe touching to the object to be measured tightly.
The Surface Temperature Sensor is mainly used to measure temperature on metal surface and liquid or gas temperature in sealed container or tubes.
Typical experiment
-
Conversion between work and energy.
-
Comparison on heat conduction performance of different substances.
Notes
-
The sensor probe should be completely insert into sensor.
-
The probe should be touching tightly to the metal surface.
-
Do not measure the temperature exceeding the measuring range.
