Handheld Digital Tachometer
HT-6200
The HT-6200 Digital Handheld Tachometer is a battery-powered handheld tachometer that integrates the measurement and display units to measure the rotation of gasoline/diesel engine and EV/HEV motor.
Depending on the measurement target and application, it can be combined with various optional detectors (VP-220/1220 engine rotation detectors, IP-292/IP-296 or IP-3000A/IP-3100 ignition pulse detectors, OM-1200/1500 Electromagnetic Detectors, MP series Electromagnetic Detectors, TTL signal output detectors, etc.) to measure the rotational speed of the target rotating body. The measurement data can be stored in the main unit up to 20 data points thanks to the memory function, making it convenient for later verification.
The measurement items include rotational speed (r/min, r/s), accumulated rotation count (count), period (ms), and peripheral speed (m/min), among others. Both analog output (switchable with monitor output) and pulse output are standard features; the analog output is for recording with data recorders (the monitor output is for sensor waveform confirmation or as an analysis input signal for FFT analyzers), while the pulse output can be used as a tracking analysis signal for FFT analyzers.
Please note:
The HT-6200 may not be able to measure depending on the type of engine and motor, or the measurement range may vary.
For engines or motors that have not been used, please confirm with a demo unit. For demo units, please contact your nearest sales office.
*We sincerely apologize, but we kindly ask that you provide the dry batteries yourself.
Regarding the installation of the detector.
When installing the detector on the engine or motor for driving tests, be sure to clean the surface of the motor with a degreaser, and use fixing brackets, etc., to wrap the detector and cables around the engine and motor parts with wire, securing them adequately with duct tape for use.
OM-0102 has holes for attaching a fall prevention wire, so please make use of them. For safety, please take sufficient fall prevention measures.
Noise and Vibration Tracking Analysis
The pulse output signal of the HT-6200 can be used for tracking analysis.
By simultaneously measuring acoustic and vibration data with the pulse signal of the HT-6200 using an FFT analyzer, ratio analysis and other analyses are possible.
Diesel Engine Tachometer
By using the Engine Rotation Detector (VP-1220) and HT-6200, it is possible to measure the Diesel Engine Tachometer. The VP-1220 detects engine vibrations and measures engine speed.
(Measurement may not be possible for more than 6 cylinders)
Measurement of motor rotation in hybrid vehicles.
By using the EV/HEV motor rotation detector (OM-1200), it is possible to measure the rotation of motors in electric vehicles and hybrid vehicles.
The detector is installed perpendicular to the motor's rotation axis.
The measurement principle detects and measures the leakage magnetic flux generated by the motor.
It can be easily measured by simply attaching the detector to the outside of the motor.
No hole processing for the detector is required.
It is necessary to set the number of poles of the motor (pulse number P/R) in the HT-6200.
Real vehicle driving tests of hybrid cars
Using two HT-6200 units, measuring the rotational speed of the motor and engine, and data measured with a GPS speedometer (LC-8100).
Regarding the installation of the detector.
When installing the detector on the engine or motor for driving tests, be sure to clean the surface of the motor with a degreaser, and use fixing brackets, etc., to wrap the detector and cables around the engine and motor parts with wire, securing them adequately with duct tape for use.
OM-0102 has holes for attaching a fall prevention wire, so please make use of them. For safety, please take sufficient fall prevention measures.
Measurement of motor rotation in electrical equipment
Using the motor rotation detector (OM-1200), it is possible to measure the rotation of motors in electrical devices such as power steering motors and air conditioning fan motors.
The detector is installed perpendicular to the motor's rotation axis.
The measurement principle detects and measures the leakage magnetic flux generated by the motor.
Therefore, it is possible to measure even when the rotation axis is hidden.
The pulse output signal of the HT-6200 can be used for tracking analysis.
By simultaneously measuring acoustic data and the pulse signal from the HT-6200 with an FFT analyzer, tracking analysis becomes possible.
