Product Introduction
The Differential Remote Pressure Gauge is a rugged, high-performance instrument tailored for critical pressure measurement scenarios. Unlike standard gauges, it combines two key capabilities: differential pressure detection (measuring the pressure difference between two points) and long-range signal transmission, making it ideal for processes where measurement points are inaccessible or hazardous.
At its core, the gauge features a vibration-resistant design-often enhanced by liquid-filled casings and robust internal components-that maintains accuracy even amid mechanical turbulence . For extreme temperatures, it integrates advanced diaphragm seals with high-temperature silicone oil fill fluid, enabling reliable operation up to 400°C (752°F) . Wetted parts are constructed from corrosion-resistant materials such as Inconel 600 or Hastelloy C276, ensuring compatibility with aggressive media like sulfuric acid, high-viscosity heavy oil, and alkaline solutions .
Beyond on-site readouts, the gauge transmits pressure data to remote moving-coil instruments via stable signals (compatible with 4-20 mA outputs as standard), enabling centralized monitoring, automated process adjustment, and instant alarm activation for pressure deviations . This dual-display functionality eliminates the need for on-site personnel in dangerous zones, boosting operational efficiency and safety.
Core Features
Vibration & Shock Resistance: Liquid-filled enclosures and reinforced internal mechanisms comply with IEC 60068-2-6 vibration standards, ensuring stability in high-dynamics environments (e.g., industrial pumps, compressors).
Extreme Temperature Compatibility: With diaphragm seals and capillary systems, it operates reliably from -40°C (-40°F) to 400°C (752°F)-surpassing the limits of traditional gauges.
Corrosion & Viscosity Tolerance: PTFE or PFA-coated diaphragms and superalloy wetted parts resist corrosive media (e.g., acids, alkalis) and prevent clogging by high-viscosity fluids like molten plastics.
Dual-Range Remote Transmission: Delivers real-time data to distant moving-coil instruments, supporting calibration via push-button zero functions for minimal downtime.
Safety Certifications: Meets Ex d/Ex ia standards for hazardous areas and SIL 2/3 requirements for safety-critical systems, ensuring compliance in oil, gas, and chemical plants.
