SS100 Sensor Simulator

CRBasic Measurement Instruction:

VoltSe (WindDir,1,mv2500C,1,1,0,_60Hz,360/2200,0)

Wind Speed (Use SS100 High Frequency Pulse Output)

Range: 0-50 m/s

Accuracy: +/- 5% > 5 m/s or 0.2 m/s < 5 m/s

Resolution: 0.1 m/s

Wind Speed Output: Linear, Calm = 3Hz, 50 m/s = 140 Hz

Multiplier and offset calculation:

Using the equation of a line with two known points (0,3) and (50,140):

y=mx + b; m = (50-0) / (140-3) = 0.365 m/s / Hz

b=y-mx; 50 - .365(140) = -1.095 m/s
