Reflection detection distance |
20 to 300 mm |
|
Display |
5-digit LED, with backlight (character height: 10.2 mm) |
|
Measurement time |
Within 1 s + time required for one cycle (however, when the rotation is less than 60 r/min, twice the time required for one cycle (MAX)) |
|
Display update time |
Approx. 1 s |
|
Measurement accuracy |
Displayed value* x (±0.02%) ± 1 count
* The displayed value is the count value excluding figures after the decimal point.
|
Note: |
▉ |
The measurement accuracy of the circumferential speed depends on the number of rotations of the rotating object. |
| |
▉ |
The measurement accuracy given above is for non-contact measurement. Measurement errors caused by hand shake are not included. With contact measurement, the smoothness and accuracy of the contact tip are added to the above value. |

|
Peak hold function |
Maximum value (MAX), minimum value (MIN) |
|
Memory function |
20 data (MAX) |
|
Over-range function |
The over-range alarm (ERROR mark) is displayed when the measured value exceeds the display range. |
|
Rotation upper limit alarm function |
The upper limit alarm ( ↑ mark) is displayed when the number of rotations exceeds the preset upper limit value. |
|
Line speed calculation function |
•Calculates the line speed from the preset diameter value (mm) and the measured number of rotations <Non-contact>
• Use the KS-100/200 circumferential rings <Contact> |
|
Accumulating function |
Provides a cumulative count of the input signal pulses |
|
Cycle measurement function |
Measures the input pulse cycle (however, when the cycle is less than 1 s, measures the mean value of the input pulses) |
