Its robust construction and intelligent design ensure reliable performance in even the most demanding environments, from offshore oil platforms to chemical processing plants. As a cornerstone for flow, level, and pressure measurement, the 3051 is engineered to provide decades of maintenance-free service, making it an indispensable tool for optimizing process efficiency and safety.

Core Features & Advantages

1. Superior Accuracy and Long-Term Stability

• Unmatched Precision: Boasts an industry-leading accuracy of ±0.075%of calibrated span, ensuring the highest data integrity for critical control and monitoring decisions.

• Advanced Sensor Technology: Features a single, monolithic capacitive sensor with oil-free, welded construction. This design eliminates mechanical linkages, minimizes hysteresis, and provides excellent resistance to shock, vibration, and overpressure conditions.

• Near-Zero Drift: Exceptional long-term stability due to advanced temperature compensation algorithms and robust sensor design, significantly reducing the total cost of ownership by extending calibration cycles.

2. Intelligent Communication and Diagnostics

• Seamless Integration: Provides a standard 4-20mA analog output for compatibility with existing legacy systems.
  Digital Brain: Embedded with the HART7 protocol (standard), enabling bidirectional digital communication for remote configuration, calibration, and diagnostics using any HART communicator or asset management software.
  Advanced Diagnostics: On-board diagnostics continuously monitor the health of the transmitter and the process, providing early warnings for potential issues such as sensor drift, electrical problems, or process anomalies.

3. Robust Design for Harsh Environments

• Exceptional Durability: Constructed with a heavy-duty, all-welded stainless steel sensor module and a weatherproof, corrosion-resistant aluminum or stainless steel housing.
  Highest Protection Ratings: Achieves an IP67 (NEMA 4X) enclosure rating, making it dust-tight and capable of withstanding temporary immersion, ideal for outdoor and wash-down applications.
  Intrinsic Safety for Hazardous Areas: Certified to ATEX, IECEx, FM, and CSA standards for Intrinsic Safety (Ex ia) and Flameproof (Ex d) protections, ensuring safe operation in hazardous locations (Class I, Division 1).

4. User-Centric Design and Easy Maintenance

• Local Parameter Adjustment (LPA): Features a magnetic push-button configuration system allowing for safe and easy zero and span adjustment without opening the housing, preserving its integrity.

  OLED Display Option: An integral, large-screen OLED display provides a local readout of pressure (in selected engineering units), percentage of range, and output current, along with diagnostic messages.

• Unmatched Flexibility: Offers a wide range of options for process connections (flange types, materials like Hastelloy or Tantalum), filling fluids (silicone oil, fluorocarbon), and electrical connections to meet exact application requirements.

5. Wide Operational Capabilities
Extensive Pressure Ranges: Available in a vast array of calibrated spans, from very low differentials (0.1 inH₂O) to very high line pressures (up to 6000 psi).
Broad Temperature Tolerance: Performs reliably across an extreme ambient temperature range from -40°C to 85°C (-40°F to 185°F).
