How to Use?
Steps
- Attach the magnet to the device you want to test
- Align the Hall sensor to the magnet and connect the sensor to the module
- Connect the module to the power supply, and you can start the test.
Please Notes
- The Hall switch is an NPN normally open switch with a diameter of 12mm;
- The magnet cannot be installed on the metal iron material, it will interfere with the detection;
- Please pay attention to the front and back when installing the magnet;
- Mechanical switches are not recommended.
Description
Features
- The proximity sensor is accurate and the speed measurement is reliable
- High speed measurement range
- It is an AC controller
- It is simple and convenient to install
- It has a long service life
- LED digital screen display
Incorrect Usage and Solutions
- Incorrect Usage: The eccentric turntable shakes up and down when rotating, resulting in inaccurate speed.
- Solution: Replace the eccentric turntable with a circular turntable that rotates along a circular trajectory to ensure accurate speed measurement.
- Incorrect Usage: The magnet is not secured, leading to inaccurate detection.
- Solution: Ensure that the magnet is firmly fixed on a level surface to improve detection accuracy.
- Incorrect Usage: Please do not hold the Hall switch or motor while taking measurements.
- Solution: Securely fix the Hall switch and motor to ensure stable measurements.
