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.
Figure 2. Resistance-Temperature Curve for a 100 Ï Platinum RTD, a = 0.00385. This relationship appears relatively linear, but curve fitting is often the most accurate way to make an accurate RTD measurement.The most common RTD is the platinum thin-film with an a of 0.385%/Â°C and is specified per DIN EN 60751.his relationship appears relatively linear, but curve fitting is often the most accurate way to make an accurate RTD measurement.
