B. Working Principle
The R-Tek Tachometer uses a Class II laser for rotational speed measurement. The instrument is positioned approximately 50 to 500 mm from the rotating component being measured. It detects the rotational movement and calculates the rotational speed, displaying the result in RPM on its 5 digit LCD screen.
The instrument samples the measurement once per second and uses a quartz crystal time base to support speed measurement.
For lower rotational speeds between 2.5 and 999.9 RPM, the display resolution is 0.1 RPM. From 1,000 to 99,999 RPM, the resolution is 1 RPM.
C. Why Is a Tachometer Used?
A tachometer is used to determine how quickly a motor, shaft, fan, drum, spindle or other rotating component is operating.
Accurate RPM measurement is important because abnormal rotational speed can indicate improper machine settings, process variation or equipment performance problems.
The R-Tek Tachometer can be used for:
- Motor RPM measurement
- Fan speed measurement
- Shaft rotational speed checking
- Spindle speed measurement
- Drum speed measurement
- Impeller speed measurement
- Machinery testing
- Equipment maintenance
- Production machinery inspection
- Automobile applications
- Textile machinery testing
R-Tek specifically identifies applications involving motors, fans, washing equipment, textile machinery, automobiles, aircraft, ships and other industries.
D. Suitable Buyers
The R-Tek Tachometer and RPM Meter may be suitable for:
- Industrial maintenance engineers
- Electrical engineers
