HT5500 photoelectric contact tachometerDetailed product description：

HT5500 photoelectric contact tachometer
Characteristics
The speed measurement range is 6.0-99999 r/min - covering a wide range of low-speed and high-speed domains
Lo range 6.0-600.0 r/min (rounded to one decimal place)
Hi Range 6-99999 r/min

Dual purpose model that combines contact and non-contact measurement
Has memory storage function, can save up to 20 data
Even in non-contact measurement, as long as the diameter of the rotating object being measured is set, the circumferential velocity can be measured
(When conducting contact testing, the measuring probe must be replaced with a contact type circumferential linear velocity measuring ring KS-100/200)
Accumulated rotational speed (contact type: one pulse per revolution; non-contact type: one pulse per reflected signal received, accumulated to 99999)
Analog output and pulse output are standard specifications
Analog output 0-1V/0-F.S. (F.S. can be set arbitrarily), 10 bit D/A conversion
Pulse output Hi: greater than+4.5V, Lo: less than+0.5V

Can use AC power supply (with AC adapter PB-7080)
Equipped with peak holding function (able to display the maximum and minimum values of rotational speed, cycle, and circumferential linear velocity)

Brief specification of HT5500 photoelectric contact tachometer

Display section	LCD display with 5 digits and background lighting
Measurement interval	Within 1 second+1 cycle When the measured speed drops below 60r/min, the maximum measurement time is twice the period
Refresh interval for data display	About 1 second
measurement accuracy	Display value (*) × (± 0.02%)=± 1 digit The displayed value is a count value without a decimal point (Note) ◆ The measurement accuracy of circumferential linear velocity is determined by the rotational speed of the measured rotor. ◆ The above measurement accuracy is a non-contact measurement method and does not include errors caused by hand shaking during measurement. When the measurement method is contact mode, the slip of the measuring probe will also affect the accuracy.
Peak holding function	Maximum value (MAX) and minimum value (MIN)
Memory storage function	Up to 20 data can be stored
Overflow function	When the measured value exceeds the measurement range, an overflow (ERROR mark) is displayed
Speed upper limit warning function	When the measured speed exceeds the pre-set upper limit, an upper limit warning (↑ mark) is displayed
The calculation function of circular linear velocity	Based on the pre-set diameter (mm) of the object being measured and the measured rotational speed, Calculate the circumferential linear velocity of the measured object (non-contact mode). When the measurement method is contact mode, Can be directly measured using the attached circular speed measuring ring KS-100/200
Cumulative calculation function	Accumulate and count the pulses of the input signal
Cycle measurement function	Measure the period of the input pulse (but take the average value when the period of the measured input pulse is less than 1 second)
