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.
Objective www.ti.com 1 Objective The objective of this application note is to describe a firmware method for monitoring two RTD's for a heatmeter application. 2 Background Resistance Temperature Detectors (RTD), measure temperature by relating the resistance of the RTDelement with temperature.latinum is the mostwidely specified RTD element type due to its wide temperature range, accuracy, stability, as well as thedegree of standardization among manufacturers. Nickel, copper, and nickel-iron alloys are also used.RTDs are often characterized by their base resistance at 0Â°C.
