Features & Benefits1.Exceptional Sensitivity for Micro-Pressure Measurement Range: From 0-0.1 kPa to 0-10 kPa (adjustable), optimized for detecting minute pressure differentials in air, gas, or liquid systems. ±0.075% Span Accuracy: Ensures precise readings for processes requiring ultra-fine control, such as cleanroom airflow or filter monitoring. 2.Robust and Compact Design Dual-Chamber Housing: Isolates electronics from process media, enhancing resistance to condensation, dust, and mechanical stress. Lightweight Aluminum Alloy: Compact and corrosion-resistant, suitable for confined spaces or harsh environments. 3.Smart Communication Capabilities 4-20 mA + HART/BRAIN Protocols: Seamless integration with DCS, PLCs, and IoT platforms for real-time data monitoring and predictive maintenance. Local Parameter Adjustment: Built-in LCD display and push buttons for on-site configuration without external tools. 4.Environmental Resilience Wide Temperature Range: Operates reliably from -40°C to 85°C (-40°F to 185°F) with optional IP67/IP68 protection for waterproof/dustproof performance. Explosion-Proof Certification: Compliant with ATEX, IECEx, and FM/CSA standards for hazardous area installations (Zone 0/1/2). 5.Low Maintenance & High ROI Long-Term Stability: Minimal drift over time reduces calibration frequency and operational downtime. Self-Diagnostic Functions: Detects sensor anomalies, wiring faults, and process irregularities for proactive maintenance. |
