IV. Installation and Usage Instructions
When installing the EC119 922-119-000-003-P1000-U1000, 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.
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.
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.
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.
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.
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.
