Edition 2013-03-26 - V04 R01
Part No.: 669855
Examples of frequency measurements:
1) You would like to measure a frequency up
to 1000 Hz. Frequencies are recorded by the
HMG per minute. Enter "60" as the
Factor
to
display the frequency in
Hz
, enter "1000" for
the
Upper measurem. range
to scale the Y-
axis from 0 to 1000 in the graphical display.
2) You would like to measure the speed of a
machine from 0 to 2900 rpm, the speed sen-
sor supplies 2 pulses per revolution. Enter
"2" as the
Factor
and "3000" as the
Upper
measurem. range
. The display is then in
revolutions per minute; for the graphical dis-
play, the Y-axis is scaled from 0 to 3000.
3) A flow rate measurement transmitter in a
measurement range up to 450 l/min with a
frequency output supplies 8 pulses per litre.
Enter "8" as the
Factor
and "500" as the
Up-
per measurem. range
. The display is then in
l/min; for the graphical display, the Y-axis is
scaled from 0 to 500.
Examples of count pulses:
1) The switching output of a proximity switch
on a conveyor belt is connected to the fre-
quency input of the HMG 3010. Enter "1" as
the
Factor
and the expected maximum
quantity to be counted (maximum 30000) as
the
Upper measurem. range
.
2) A gear flow meter supplies 250 pulses per
liter. Enter "250" as the
Factor
and as the
Upper measurement range
, the maximum
no. of litres expected (maximum 30000).
