DC 8-24V 4 Bit Digital LED Tachometer Motor RPM Speed Meter Hall Sensor Switch Motor Speedometer Counter Tachometer

Description:

The Hall-type rotational speed sensor belongs to the Hall-type sensor and is made by the principle of Hall effect. The Hall effect is used to make the displacement of the Hall element move in the magnetic field to generate the Hall potential, that is, the displacement signal is converted into the potential change signal.
The display will be based on the signal received by the Hall sensor and calculate the rotational speed of the measured device.Also displayed on the display.

5>.Production workshop;
6>.Store.

6.Note:
1>.Connect correctly according to the wiring diagram.
2>.It is recommended to use shielded wires or twisted pairs for measuring wires to avoid strong electromagnetic interference.
3>.It is recommended to use short wires to avoid excessive length of the wires, resulting in unpredictable interference.
4>.Mechanical switches or micros witches are not recommended.
5>.Please check if the test object is rotating at a constant speed and the installation is stable if the display data changes frequently.
