Working Principle of SZCB-01 series Magneto-Resistive Speed Sensor
When using the SZCB-01 series Magneto-Resistive Speed Sensor, a gear (spur gear, helical gear, or grooved disc can be used) should be installed on the shaft whose speed is to be measured. Install the sensor on the bracket and adjust the gap between the sensor and the gear top to about 1mm.
When the shaft rotates, it drives the gear to rotate. A voltage pulse signal is generated at both ends of the coil in the sensor.
When the gear teeth is 60, the number of revolutions per minute n of the shaft is converted into a voltage pulse signal of frequency F, and this signal is sent to the tachometer to reflect the speed of the shaft.
Precautions of SZCB-01 series Magneto-Resistive Speed Sensor
1. The metal shields in the sensor output line should be connected to the earth neutral line.
2. Do not use and place in a strong magnetic field environment with a temperature above 25℃.
3. Avoid strong impact during installation and transportation.
4. When the measured shaft has a big runout, pay attention to enlarge the gap appropriately to avoid damage.
5. For the usage in harsh environment, the sensor is sealed immediately after assembly and debugging, so it cannot be repaired.
