Rotary Pulse Indicator
K3HB-R
CSM_K3HB-R_DS_E_9_1
Digital Rotary Pulse Meter Capable of 50 kHz Measurements
• Visual confirmation of judgement results through display colors that switch
between red and green.
*1
• 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/instantaneous
flowrate (value proportional to frequency), absolute ratio, error ratio, error, flow rate
ratio, and passing speed (value inversely proportional to frequency).
• DeviceNet models added to the series.

*1
Visual confirmation of judgement results is not supported on models that do not have an output
or models that do not support DeviceNet.
You can change the display color by setting it, but you cannot switch it based on the judgement results.
*2
DeviceNet models have a depth of 97 mm.

Functions (Operating Modes)
F1 to F6
Functions F1 to F6 provide rpm/circumferential speed and other calculation displays by measuring continuous pulses (frequencies).

Displays rotation (rpm) or circumferential speed for one input.
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.
