Rotary Pulse Indicator
K3HB-R
Digital Rotary Pulse Meter Capable of 50 kHz
Measurements
• Measures High-speed Pulses at 50 kHz.
Provides high-speed pulse measurements up to 50 kHz of rotary
encoder or ON/OFF pulse signals and can perform rotating
measurement of high-speed rotating objects.
Note: No-voltage contacts of up to 30 Hz are supported.
• Six Measurement Operations Including Rotation (rpm)/
Circumferential Speed, Ratio, and Cumulative
One Rotary Pulse Meter has 6 rotary pulse measurement functions to
support a variety of pulse measurement applications. Select the best
function for your application from the following: rotation (rpm)/
circumferential speed, absolute ratio, error ratio, error, flow rate ratio,
and passing time.
Refer to Common Precautions on page 30.

F1: Displays rotation (rpm) or circumferential speed for one input.
F2 to F5: Displays the calculation result for two rotation (rpm) speeds.
F6: Displays the passing time calculated from the circumferential speed and the length
of the processing stage for one input.
The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is
to count the ON/OFF time (T) for input sensor or other device inputs using the internal system
clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and
displayed as the rotation (rpm) speed.
Input sensor or other input pulse ON/OFF time (T) =
T
Frequency (f) =
1
T
Rotation speed (rpm) = f × 60
Circumferential speed = Roll circumference × Rotation speed (rpm)
Passing time= Length of processing stage
Circumferential speed
These calculations are automatically made internally and displayed whenever any input pulse
is received.
