EXAMPLES OF
“MUL” AND “DIV
” PARAMETERS CALCULATION
1.
Let's assume that user wants to multiply rotational speed by 12.34. Then parameters
“
mUL
”
and
“
div
”
should be set :
“
mUL
”
= 1234,
“
div
”
= 100
2.
Let's assume that user wants to divide rotational speed by 5.678. Then parameters
“
mUL
”
and
“
div
”
should be set :
“
mUL
”
= 1000,
“
div
”
= 5678
3.
Let's assume that user wants to display linear speed of moved material. Measurement
wheel radius is 5 cm. To determine parameters
“
mUL
”
and
“
div
”
a circumference of
measurement wheel must be calculated (it means linear distance equals to single
revolution)
circumference
= 2 x 3,14 x 5 cm = 31,40 cm = 0,314 m
To obtain linear speed multiply rotational speed by determined coefficient:
“
mUL
”
= 314,
“
div
”
= 1000
After storing these parameters, device displays linear speed of material movement
expressed in m/s , m/min. or m/h ( depend on
“unit”
parameter), with precision selected
by
“PrEc”
parameter
.
4.
Let's assume that user wants to know how much time is required for backing a bun at
current speed of production line. While backing the bun is moving on the production line
through the oven.
Input data:
–
number of pulses per 1 meter = 10 pulses
–
the way of bread while backing = 12.33m
User have to set following parameters:
•
“
inPUt
”
->
“F or P”
=
“
PEriod
”
•
“
inPUt
”
->
“PULSen”
= 10 pulses
•
“
inPUt
”
->
“
div
”
=
37
(because we want to N*12.33 be an integer value)
•
“
inPUt
”
->
“
mUL
”
= N
Since now the time (required for backing a bun at current speed of production line) is
shown on the display (in units selected by “
inPUt
” -> ”unit” parameter).
