HT5550 thiết bị đo tốc độ vòng quay

Detection methods

Optical reflective non-contact measurement; contact method (contact adapter supplied)

Measurement units

r/min, r/s (rotations)
m/min (line speed)
ms (cycle)
COUNT (cumulative count)

Measurement ranges

	Non-contact method	Contact method
r/min (Hi range)	6 to 99999	6 to 20000
r/min (Lo range)	6.0 to 600.0	6.0 to 600.0
r/s	0.10 to 999.99 r/s	0.10 to 400.00 r/s
m/min	0.6 to 9999.9 m/min	0.6 to 400.0 m/min
COUNT	0 to 99999 COUNT	0 to 99999 COUNT
ms	0.6 to 9999.9 ms	2.5 to 9999.9 ms

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
• Use the KS-100/200 circumferential rings

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)
