The wiring method of displacement sensor DET150A in use should pay attention to the following matters:
Selection of wiring method
Two line connection method: relatively simple, usually used in small or simple systems. One of the wires is connected to the positive pole of the power supply, while the other wire serves as both the negative pole of the power supply and the signal output. It should be noted that power fluctuations may directly affect signal output, so signal stability should be carefully considered when using long-distance transmission.
Three wire connection method: provides higher flexibility and accuracy. In addition to the positive and negative poles of the power supply, the third wire is dedicated to signal output. This method can effectively reduce the impact of power fluctuations on signals and is suitable for situations that require high measurement accuracy.
The four wire connection method is more complex, usually consisting of two pairs of wires: positive and negative for the power supply and positive and negative for the signal. This connection can further improve the stability and anti-interference ability of the signal, especially suitable for long-distance transmission and high-precision measurement in industrial environments.
Wiring steps
1. Preparation work: Before starting the wiring, confirm that the appropriate displacement sensor DET150A, required tools, and connecting wire materials have been obtained.
2. Connect the power and signal lines: Connect the controller to the sensor according to the markings on the sensor and secure it in place. Confirm the correspondence between the colors of the connecting wires. Incorrect wiring may result in inability to read data or increase errors.
3. Check the connections: Ensure that all connections are firm and reliable, avoiding measurement errors caused by poor or loose contact.
precautions
Power stability: The DET150A displacement sensor has certain requirements for the power supply voltage, which is generally between 5V and 36V, and should not exceed 36V, otherwise it is easy to burn out the circuit. The power supply voltage should be stable, and industrial power sources require a stability of ± 0.1%.
Avoid interference: When wiring, pay attention to shielding and anti-interference measures to avoid the impact of external electromagnetic interference on signal transmission. Shielding can be achieved by using shielded cables, wrapping a metal shielding layer around the sensor, and grounding the sensor and signal lines properly.
Cable protection: The external wiring of the displacement sensor should be welded at the waist groove of the lead out end, and should not be welded at the top of the lead out end as much as possible. The cable should be firmly connected without damage to avoid signal loss or interference; The layout of cables should avoid excessive bending or pulling to prevent damage to internal wires or affect signal transmission quality.
Environmental protection: Water droplets, vapors, solvents, and corrosive gases should be prevented from invading the displacement sensor, and metal shavings or other powders should be prevented from entering the sensor.
Safe operation: Caution should be exercised during operation to avoid causing harm to equipment or oneself.
