Product Information of EMERSON DA7281520 P152

1. Main Technical Specifications

2. Product Features

• High-Precision Particulate Detection: Adopts laser scattering technology, enabling stable measurement within a wide temperature and pressure range.
• Multi-Protocol Communication: Built-in HART device description, supporting fieldbus and Ethernet, facilitating integration into DCS/SCADA systems.
• Self-Diagnostic Function: Equipped with automatic self-inspection, sensor health monitoring, and fault alarm functions, reducing maintenance costs.
• Modular Design: The sensor, electronic module, and display panel can be quickly replaced, improving on-site maintenance efficiency.
• Durability: With IP66 protection class, it is suitable for harsh industrial environments (such as high temperature, corrosive gas, etc.).
• Flexible Output: Provides multiple output methods including analog quantity, relay, and digital communication, meeting different control requirements.

3. Structure and Composition

• Sensor Unit: Laser scattering particulate sensor, equipped with a protective filter and a calibration port.
• Electronic Control Box: Includes a signal processing chip, communication module, power management, and diagnostic circuit.
• Display Panel: Local operation interface, displaying real-time concentration, alarm status, and system diagnostic information.
• Mounting Bracket/Flange: Can be directly installed on pipeline flanges or brackets, with anti-vibration gaskets.
• Supporting Accessories: Includes HART adapter, remote I/O module, calibration gas interface, etc.

4. Typical Application Fields

• Power Industry: Monitoring of particulate emissions from coal-fired boilers and gas turbines.
• Iron and Steel Metallurgy: Online monitoring of high-temperature flue gas and dust removal systems.
• Chemical and Petrochemical Industry: Emission control of reaction kettles and distillation towers.
• Cement and Building Materials Industry: Kiln emission and dust control.
• Environmental Supervision: Continuous Emission Monitoring Systems (CEMS) for government or third-party monitoring stations.

5. Installation Key Points

• Site Selection: Ensure the sensor inlet is far from direct air flow, heat sources, and vibration sources, and maintain a sufficient sampling length (≥ 5 times the pipe diameter).
• Flange Connection: Use supporting flange gaskets to ensure tightness; tighten bolts evenly to prevent leakage.
• Power Supply and Grounding: The 24 V DC power supply needs to be filtered, and the equipment shell must be reliably grounded.
• Communication Wiring: Use shielded twisted pairs for HART/Modbus, and keep the wire length within the specified range (≤ 300 m).
• Calibration and Commissioning: Perform zero calibration and range calibration after the first installation, using calibration gas or standard particulate sources provided by the manufacturer.

6. Maintenance

• Regular Inspection: Check the protective filter and sensor optical window for dust accumulation or scaling every 3 to 6 months.
• Self-Diagnostic Log: View the equipment self-inspection report through HART or the local panel, and replace faulty components in a timely manner.
• Calibration Cycle: A complete calibration is recommended every 12 months; it can be shortened to 6 months under special working conditions.
• Spare Part Replacement: The sensor module, optical window, and electronic board are all hot-swappable spare parts, and the on-site replacement time is ≤ 30 minutes.
• Firmware Upgrade: Regularly check the firmware version released on Emerson’s official website; upgrading can improve measurement algorithms and communication compatibility.
