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.
esistance temperature detectors (RTDs) operate on the inherent propensity of metal to exhibit a change in electrical resistance as a result of a change in temperature. We are all aware that metals are conductive materials.
