Installing a port intrinsically safe explosion-proof linear displacement sensor requires careful planning and strict safety control. First, confirm the hazardous area classification, gas group, and temperature class. Verify that the sensor, barrier, and associated equipment are certified for the location. Isolate power and follow lockout/tagout procedures before work begins. Inspect the sensor for damage and check that its thread, stroke, and electrical rating match the application. Mount the sensor on a rigid, vibration-free bracket. Keep the measuring axis aligned with the moving target to avoid side load and mechanical wear. Use insulated or approved mounting hardware and maintain the required isolation distance. Route cables through certified explosion-proof cable glands or conduit. Do not open the enclosure in a hazardous atmosphere. Connect wiring according to the control drawing, using the specified intrinsically safe barrier or galvanic isolator. Keep signal and power cables separated from high-energy lines. Terminate the shield as instructed, and complete equipotential bonding and grounding. Tighten glands and covers to the required torque. After installation, inspect seals, connections, and markings. Energize the circuit only after all checks pass. Perform zero and span calibration within the safe range, and record the results. During maintenance, use only approved parts. Regular inspection of cables, glands, grounding, and enclosure integrity helps ensure reliable, safe operation.
