China Tachometer suppliers Product Introduction TA501A non contact tachometer, adopts photoelectric, anti-interference, semiconductor laser a to realize non-contact measurement of rotation speed, with wide measurement range and high resolution. The digital rpm tachometer is suitable for electric power, steel, petrochemical, aviation, fan manufacturing, duct ventilation systems, underground warehouses and other industries measuring speed. The non contact tachometer has max/min/avg measurement, upper/lower limit dual-color background light alarm, and ambient temperature measurement. During the measurement, cut a square reflective tape of 12mm. If the shaft surface reflects obviously, paint it to black or stick it with black tape first before sticking the tape on it. Please also make sure the tested object stopped before sticking tape to prevent the operator from being injured. And the reflective tape should be stuck smoothly and cleaned on the surface.
