8. EXAMPLES OF PRESCALER PARAMETERS CALCULATION
Problem: to measure length of the line with assumed precision.
Essential data :
- number of pulses per revolution given by sensor
- circumference of measurement circle
- assumed measurement resolution
Example 1
Data:
- circumference of measurement circle: 25 cm
- number of pulses: 100 pulses/revolution
- resolution 1 cm
25 cm = 1 revolution = 100 pulses
it means 1 cm=4 pulses
Settings :
mul=”1”
div = “4”
decimal point = “0.”
Obtained range of measured distances 1 cm
to 10 m.
Example 2
Data:
- circumference of measurement circle: 10 cm
- number of pulses: 100 pulses/revolution
- resolution 10 cm
10 cm = 1 revolution = 100 pulses
Settings:
mul=”1”
div = “100”
decimal point = “0.0”
Obtained range of measured distances 10 cm
to 100 m.
Example 3
- counter
SLN-94
used in batcher function (see: Figure 6.1, 6.2)
Data:
–
flow meter:
100
pulses / L
–
main valve flow (valve 1): about 10 L / sec.
–
additional valve flow (valve 2): about 1 L / sec.
–
measurement precision: up to 0,1 L.
–
valves are open while relays are closed
Settings:
mul=”1”
div = “10”
decimal point = “0.0”
Pr2 = ”1.0” - control advance (main valve will be closed when counter reach Pr1 - Pr2 )
Pr1
- desired volume of medium
“mod” = “ bat” - batcher mode
„ dir ” = „UP” - upcounting – counter shows current volume of medium
