Resistance thermometers, also called resistance temperature detectors ... it is the contact temperature measurement device commonly found in physics laboratories. ...
Like the BaTiO 3 thermistor, this device has a highly nonlinear resistance/temperature response useful for thermal or circuit control, not for temperature measurement. Besides circuit elements used to limit current, self-limiting heaters can be made in the form of wires or strips, useful for heat tracing .
Temperature measurement ... One of the most common devices for measuring temperature is the glass thermometer. ... Resistance temperature detector (RTD)
Pyrometers principle: temperature dependence of spectral intensity of light (Planck's law), i.e. the color of the light relates to the temperature of its source, range: from about −50 °C to +4000 °C, note: measurement of thermal radiation (instead of thermal conduction, or thermal convection) means: no physical contact becomes necessary in ...
Thermopiles are used to provide an output in response to temperature as part of a temperature measuring device, such as the infrared thermometers widely used by medical professionals to measure body temperature, or in thermal accelerometers to measure the temperature profile inside the sealed cavity of the sensor. [4]
The transistor's manufacturer will specify parameters in the datasheet called the absolute thermal resistance from junction to case (symbol: ), and the maximum allowable temperature of the semiconductor junction (symbol: ). The specification for the design should include a maximum temperature at which the circuit should function correctly.
