Intelligent elevator renovation sensor

1、 Overview

Intelligent elevator renovation sensorUsing the principle of interaction between ferromagnetic materials and current to detect changes in magnetic field. When current passes through a conductor, a certain voltage is generated on both sides of the conductor, and this phenomenon is amplified when the conductor is in a magnetic field. Hall sensors detect the required information by measuring changes in this voltage. In elevator motors, Hall sensors can detect changes in the motor's magnetic field, thereby achieving monitoring of parameters such as elevator motor speed, position, and direction.

2、 Application of Hall sensors in elevator scenarios

Monitoring elevator motor speed:Intelligent elevator renovation sensorIt can monitor the speed of the elevator motor in real time to ensure that the operating speed of the elevator is within a reasonable range. By adjusting the speed of the motor, safety hazards caused by the elevator running too fast or too slow can be avoided;

Determine elevator position: Hall sensors can detect changes in the magnetic field on the elevator guide rails to determine the specific position of the elevator. This position detection method is precise and reliable, which helps to achieve precise control of elevators;

Monitoring the direction of elevator operation: Based on the magnetic field changes on the elevator guide rail, Hall sensors can detect the direction of elevator operation to ensure that the elevator runs in the preset direction;

Monitoring the status of elevator doors: Hall sensors can also detect the status of elevator doors in a timely manner, ensuring that the doors automatically open and close when passengers enter and exit, and stop closing the doors when obstacles are found during the closing process to prevent accidental injuries.

4、 Precautions

Incorrect wiring may cause damage to the sensor.

The false wiring may result in the damage of the sensor.

When the direction of IP is consistent with the direction of the product arrow, the output voltage is positive.

VOUT is positive when IP flows in the direction of the arrow.

When the primary conductor fully fills the primary aperture, the dynamic performance (di/dt and response time) is optimal.

Dynamic performances (di/dt and response time) are best with a single bar completely filling the primary hole.

The temperature of the primary conductor should not exceed 100 ℃.

Temperature of the primary conductor should not exceed 100°C.
