CS410 Shaft Encoder 1. General Shaft encoders monitor fluctuations in water level and the position of water control gates by converting shaft rotation to electronic signals which are then measured by the datalogger. The CS410 generates two pulse strings—one indicating clockwise and the other counter-clockwise rotation. 2. Specifications Compatible Dataloggers: CR200-series, CR800, CR850, CR1000, CR3000, CR10(X), CR500, CR510, 21X, CR23X, CR7 Power supply: 4 to 5.
CS410 Shaft Encoder 5. Programming The shaft encoder is measured with the PulseCount instruction in CRBasic and Instruction 3 in Edlog. Dataloggers that use CRBasic are the CR200-series, CR800, CR850, CR1000, and CR3000. Our older dataloggers use Edlog. Multiplier for the PulseCount instruction or Instruction 3: The multiplier is based on the wheel circumference and the shaft encoder counts per revolution: MULTIPLIER = WHEEL CIRCUM. (in desired units)/ (COUNTS/REV.
