IV. Installation and Usage Instructions
When installing the EC119 922-119-000-003-P2000-U2000, the following points should be noted:
Probe Mounting Location: Should be selected on a stable part of the mechanical structure, ensuring no obstacles between the probe and the measured surface. The mounting surface should be flat and clean to ensure measurement accuracy. For axial displacement monitoring, ensure the probe is aligned with the thrust collar surface.
Cable Routing: Should be kept away from strong electromagnetic interference sources such as high-voltage cables and variable frequency drives. It is recommended to use metal conduits or shielded trays for wiring to enhance anti-interference capability. The cable bending radius should comply with the product manual to avoid internal damage from excessive bending.
Explosion-Proof Requirements: If used in an explosive atmosphere, the inductance and capacitance of the cable must strictly comply with EC certification requirements, and installation must strictly follow explosion-proof regulations. Explosion-proof junction boxes should be used at connection points.
Environmental Adaptability: Depending on the site conditions, consider adding armored protection or anti-corrosion coating. For high-temperature areas, ensure adequate heat dissipation space at the cable connections. For underwater or high-humidity environments, ensure all connections are well-sealed.
Calibration and Testing: After installation, system calibration should be performed to ensure accurate output signals. It is recommended to use Meggitt's calibration tools or third-party certified equipment for testing. Calibration should include zero and span adjustments.
Mechanical Fixing: Ensure the probe is firmly installed to prevent loosening or displacement due to mechanical vibration. The installation torque should comply with the values specified in the product manual. For long probes, consider adding support points to prevent resonance.
Initial Gap Setting: Set an appropriate initial gap according to monitoring requirements during installation, typically near the midpoint of the probe's range, to ensure sufficient measurement margin in both positive and negative directions.
