Kind Tips
• Packaging Inspection: Before installation, carefully inspect the packaging to ensure no damage occurred during shipping.
• Specification Check: Confirm that the transmitter's specifications (such as range, accuracy, and output signal) meet your application requirements.
Mechanical Installation:
• Flange Mounting: Ensure the flange is securely and evenly attached to the process connection with a proper gasket to prevent leaks and isolate stress.
• Threaded Mounting: Use appropriate sealant (e.g., PTFE tape) on the threads and tighten to the recommended torque to ensure a pressure-tight seal without over-tightening.
Electrical Connections & Safety:
•Correct Wiring: Strictly follow the wiring diagram (2-wire, 3-wire, or 4-wire) to connect power and signal lines. Use conduit glands to maintain the housing's ingress protection (IP) rating.
•Proper Grounding: Ensure the transmitter is properly grounded to improve interference immunity and safety.
