Development of multiple velocity and temperature probe sets for ventilated spaces
velocity temperature ventilation probe thermistor
2008/11/21
Development of a low-cost computer-based system for multi-point measurement of velocity and temperature has been completed. The principle is based on hot-wire anemometry. A typical probe consists of ...
Relationship between the impedance of a multi-pin probe and soil water content
impedance dielectric constant soil water content multi-pin probe model
2008/11/12
Based on the theory of the impedance-transform of transmission line, a mathematical model for calculating the impedance of a soil probe with a multi-pin structure was developed. It is found that the ...
