The eddy current sensor is designed based on the principle of the eddy current effect. This phenomenon occurs when a conductive material, such as a metal block, is placed in a changing magnetic field or moves through a magnetic field, causing a swirling induced current within the conductor. Eddy current sensors are widely used across various industries including power generation, oil and gas, chemical processing, and metallurgy. They are ideal for measuring vibration, velocity, and displacement of objects with high precision. Proper installation is crucial to ensure accurate measurements. When installing the probe, it's important to clean the mounting hole thoroughly and make sure there is no debris that could interfere with the probe’s operation. Additionally, avoid any contact between the probe and wires during rotation to prevent damage. To protect the probe’s tip and housing, use a non-metallic feeler gauge when checking the gap. The probe gap can be adjusted by connecting the probe wire to an extension cable and using the preamplifier’s electric method. Once the gap is set, avoid over-tightening the nut and ensure the force applied is just right. It's also essential that the extension cable length matches the preamplifier to maintain measurement accuracy. The extension cable plays a vital role in the system, connecting the probe to the front-end unit. It should be protected from physical damage and environmental factors. To maintain a secure connection, consider using Heat Shrink Tubing to reinforce the joint between the probe and the cable. When fixing the extension cable, make sure the cable tray has a diameter larger than 55mm to prevent strain and potential breakage. For the front-end unit, it is recommended to place it inside a cast aluminum enclosure to protect it from mechanical damage and contamination. Multiple front-end units can be installed in the same box without altering the probe cable length, which helps reduce costs and simplifies wiring. To minimize interference and signal noise, proper isolation and grounding techniques should be implemented. When setting up the axis vibration sensor, connect the probe, extension cable, and front-end device to the power supply. Use a high-precision multimeter to monitor the output voltage of the front-end unit and adjust the gap between the probe and the target surface. When the voltage reads between 10 and 11 VDC, tighten the two securing nuts on the probe to fix its position. Correct installation not only ensures reliable performance but also reduces long-term maintenance costs. If the sensor output is unstable due to improper installation, reinstallation may be necessary. In some cases, sensors may still be damaged despite following the guidelines. However, adhering to these installation procedures will significantly improve the reliability and accuracy of the eddy current sensor.
The self-closing feature refers to the sleeve's ability to automatically close around the cables once they are inserted into the sleeve. This eliminates the need for additional fasteners or ties to secure the sleeve in place.
The braided construction provides excellent abrasion resistance and protection against external factors such as chemicals, UV rays, and heat. It also helps to organize and streamline cables, reducing clutter and tangling.
PET self-closing braided sleeves are commonly used in industries such as automotive, electronics, and telecommunications to protect and manage cables in applications where flexibility, durability, and ease of installation are important.
