WNK55 Smart Differential Pressure Transmitter With Hart

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Precision Pressure Measurement: Equipped with ±0.075% FS accuracy, enabling precise monitoring of differential pressure in demanding applications.
  • HART Communication: Supports two-way digital communication via HART protocol for real-time data transmission and remote configuration.
  • Explosion-Proof Safety: Designed for hazardous environments with explosion-proof certification, ensuring safe operation in flammable gas zones.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a stainless steel body and IP67 protection, you can ensure reliable operation in harsh industrial environments. This outperforms standard models without IP67-rated sealing*, maintaining durability against dust, moisture, and corrosion.

  • 2. HART-Enabled Interactive Design

    • With HART two-way communication technology, you can remotely monitor and adjust parameters in real time. This surpasses traditional analog-only transmitters for enhanced flexibility and diagnostics*.

  • 3. Ultra-High Precision Performance

    • With ±0.075% FS accuracy, you can achieve precise pressure measurements critical for sensitive processes. This delivers ~25% higher accuracy than standard ±0.1% FS models*, minimizing errors in critical applications.

  • 4. Explosion-Proof Scenario Adaptability

    • With explosion-proof certification, you can safely deploy in hazardous zones (e.g., oil/gas facilities). This ensures compliance with safety standards in environments where flammable gases are present*, unlike non-certified alternatives.

  • 5. Global Compliance Certifications

    • With CE and RoHS certifications, you can meet EU safety and environmental regulations effortlessly. This eliminates compliance risks compared to non-certified devices*, simplifying global deployment.
