SS100 Sensor Simulator 1. General The SS100 is a device used when the Campbell Scientific CR1000/LoggerNet Training Course is taught out-of-house. The SS100 is powered by a nominal 12VDC power source, typically the datalogger itself, and provides several outputs typical of those from sensors commonly measured by Campbell Scientific dataloggers. The Training Course instructors may use the SS100 in a variety of simulations of their own choosing or use the analogies in this manual. 2.
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 Wiring SS100 P G CR1000 P1 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.
