ONOSOKKI Handheld Digital Tachometer – HT-5500

Handheld Digital Tachometer - HT-5500

HT-5500 is a handheld digital tachometer with high performance and pioneering technology at the sophisticated body. It can be operated easily as both contact and non-contact type digital tachometer, which various rotation measurement technology are equipped.



Various measurement parameters such as rotation (r/min, r/s), accumulated rotation (count), line speed (m/min: contact and non-contact, mm/s: contact) and period (ms) can be measured. Both the analogue signal output and pulse signal output are available as standard. Analogue signal is used for recording the rotational data at data recorder etc. Pulse signal is used as external sampling signal at FFT analyzer for tracking analysis.



Wide measurement range with high technical functions from 6.0 r/min (low-speed rotation) to 99999 r/min (high-speed rotation) is provided.

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)
