Temperature sensor - WIKA

Temperature sensors with thermocouples are suitable for the measurement of high temperatures of up to +1,700 °C. Thermocouples consist of two different metals which are bound together to form the 'thermocouple'. The connection point (hot junction) represents the actual measuring point of the temperature sensor, the wire ends are designated as the cold junction. When there is a temperature ...

Grove - Temperature Sensor - Seeed Wiki

The Grove - Temperature Sensor uses a Thermistor to detect the ambient temperature. The resistance of a thermistor will increase when the ambient temperature decreases. It's this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor is -40 - 125ºC, and the accuracy is ±ºC . Note: This wiki works with Grove - Temperature sensor as well ...

Are Infrared Thermometers Dangerous? (Doctor's Advice)

Infrared thermometers use infrared radiation emitted by bodies and objects to convert it into a screen temperature. First, emitted IR radiations from a human or body are absorbed by the lens and transferred to the thermometer’s thermopile or sensor. At the thermopile, the conversion of thermal energy into electrical energy takes place. The temperature of the thermopile or sensor increases ...

Thermopile and Infrared Temperature Sensors | TE Connectivity

Thermopile IR Temperature Sensors. Thermopile sensors are designed to measure temperature from a distance by detecting an object's infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A reference sensor is designed into the package as a ...

Principles of Non-Contact Temperature Measurement

For optimal IR sensor responsiveness, the pyrometer manufacturer must allow for the spectral sensitivity as well as the characteristic curve of the employed detector. The instrument’s electronics linearises the detector’s output signal to generate either a linearised output current 0 (4) – 20 mA or a linearised output voltage 0(2) – 10 V. Frequently the linearisation will be carried ...
