  2. δ18O - Wikipedia

    en.wikipedia.org/wiki/Δ18O

    In geochemistry, paleoclimatology and paleoceanography δ 18 O or delta-O-18 is a measure of the deviation in ratio of stable isotopes oxygen-18 (18 O) and oxygen-16 (16 O). It is commonly used as a measure of the temperature of precipitation, as a measure of groundwater/mineral interactions, and as an indicator of processes that show isotopic fractionation, like methanogenesis.

  3. Tap (valve) - Wikipedia

    en.wikipedia.org/wiki/Tap_(valve)

    A single temperature tap is commonly found in a commercial or public restroom where the temperature of the water will be controlled by a separate temperature regulating valve that mixes hot and cold water. The regulating valve may be under the handwashing sink or in a separate mechanical room or service closet.

  4. Distributed temperature sensing - Wikipedia

    en.wikipedia.org/wiki/Distributed_temperature...

    Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances. Typically the DTS systems can locate the temperature to a spatial resolution of 1 m with accuracy to within ±1 °C at a resolution of 0.01 °C.

  5. Thermistor - Wikipedia

    en.wikipedia.org/wiki/Thermistor

    NTC thermistors are widely used as inrush-current limiters and temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 and 300 °C (−148 and 572 °F).

  7. Thermoreceptor - Wikipedia

    en.wikipedia.org/wiki/Thermoreceptor

    Thermoreceptors of the skin sense the temperature of water. A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.

  8. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.

  9. Noise-equivalent temperature - Wikipedia

    en.wikipedia.org/wiki/Noise-equivalent_temperature

    Noise-equivalent temperature (NET) is a measure of the sensitivity of a detector of thermal radiation in the infrared, terahertz or microwave portions of the electromagnetic spectrum. It is the amount of incident signal temperature that would be needed to match the internal noise of the detector such that the signal-to-noise ratio is equal to one.
