It is a high-precision digital speed meter and a proximity sensor. The proximity sensor switch and the motor need to be fixed with a bracket.The more stable the fixing,the month is helpful for stable detection.
HIGH PRECISION MEASUREMENT: Measuring range: 10-9999; Measurement accuracy: ±0.1%, reading ±1 word; Display refresh rate: >3 times/second
ANTI-INTERFERENCE: Comes with Hall sensor and magnet, good stability, accurate Hall induction, reliable speed measurement, strong anti-interference ability.
LED DISPLAY: Equipped with 4-bits digital LED display, which makes the speed meter clear and easy for reading.
OVER-RANGE DISPLAY: If the rotation speed is too low, it will display "LLLL"; if the rotation speed is too high, it will display "HHHH"
1. Avoid using strong electromagnetic interference;
2. When testing, the Hall switch and the magnet need to be fixed firmly, otherwise it will cause vibration, resulting in a jumping or inaccurate reading, and the distance between the Hall switch and the magnet must be within 10mm
