CSM_K3HB-P_DS_E_15_2
Digital Time Interval Meter for Measuring
Passing Speed, Time, or Cycle between Two
Points.
• Visual confirmation of judgement results through display colors that
switch between red and green.
*1
• Measures Wide Range of Pulse Interval Times
Measures, calculates, and displays pulse intervals between two points. Wide
range for pulse interval measurements, from 10 ms to 3,200 s, max.
• Six Measurement Operations, Including Passing Speed, Time, and
Cycle Measurement between Two Points
One Digital Time Interval Meter has six measurement functions, to support a
variety of pulse interval measurement applications. Select the best function
for your application from the following: Passing speed, cycle, time difference,
time band, measuring length, and interval.
• 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.

a variety of other calculations.

What Is Prescaling?
To make calculations using the input pulse to display the passing speed between two points, the distance between the two points and the display
unit must be set and the internally measured time multiplied by a certain coefficient. This coefficient is called the prescale value. (For information
on settings details, refer to the User's Manual.)
