C4 pathway A pathway of carbon fixation, found most commonly in tropical plants that have high rates of growth and photosynthesis and that are adapted to high temperatures, strong light, low carbon dioxide levels, and low water supply. Its importance lies mainly in its reduction of photorespiration.
PT 100 RTD means Resistance temperature detector(RTD) of platinum with 100 ohms resistance at zero degree centigrade.
An RTD is a device which contains an electrical resistance source (referred to as a. âsensing elementâ or âbulbâ) which changes resistance value depending on itâs. temperature. This change of resistance with temperature can be measured and used to. determine the temperature of a process or of a material. RTD sensing elements come in two basic styles, wire wound and film. Wire wound elements.
