Omron K3HB Datasheet

8 Rotary Pulse Indicator K3HB-R
F2
Absolute
ratio
Multiples input B divided by input A ( ) by 100 and
displays the ratio as a percentage (%).
Display unit: %
Measuring the speed ratio between two rollers
F3
Error ratio
Multiplies the error between input A and input B
(
−1) by 100 and displays the ratio as a percentage
(%).
Display unit: %
Measuring the line speed error ratio between two conveyors
F4
Rotational
difference
Displays the difference between input A and input B
(B - A) as the rotation (rpm) speed error or
circumferential speed error.
Display unit:
rpm, rps, rph,
Hz, kHz, mm/s, m/s
m/min, km/h
l/min, l/h, etc.
Measuring the rotation (rpm)/circumferential speed error (absolute error)
between two conveyors
F5
Flow rate
ratio
Displays the flow rate ratio of B from inputs A and B
( ) as a ratio (%).
Display unit: %
Monitoring liquid mixture flow rate ratio
F6
Passing
time
Passing time (s) = 1/ƒa
× α
ƒa: Input frequency (Hz)
Set the prescale value for the desired display unit using
the following table for reference.
N = Pulses per rotation
πd = Circumferential length per rotation (m)
L = Length of process (m)
