FOXBORO P0700HU Differential Pressure Transmitter

Description

FOXBORO P0700HU Differential Pressure Transmitter

Product Dimensions：

Foxboro Differential Pressure Transmitters (such as the flagship Foxboro IDP10 series, produced under Schneider Electric) are high-precision field instruments engineered to measure pressure differences across liquid, gas, or steam applications.

Detailed Description

Foxboro Differential Pressure (d/p) transmitters convert the mechanical deflection caused by pressure differentials across two sensor diaphragms into standardized electrical signals. Utilizing silicon piezoresistive or resonant sensor technology, these devices deliver reliable measurement stability, wide turndown ratios, and multi-protocol communication (HART, Foundation Fieldbus, FoxCom) for seamless integration with DCS and PLC architectures.

Technical Parameters

Product Advantages

• FoxCal Technology: Advanced factory calibration eliminates the need for field re-calibration across multiple operating ranges, saving commissioning time.
• Exceptional Stability: Low long-term drift guarantees reliable performance over extended maintenance intervals.
• Corrosion Resistance: High-grade metallurgical choices (Hastelloy, Monel, Tantalum) allow reliable operation in aggressive chemical processes.
• Rugged Housing: Dual-compartment explosion-proof housing protects internal electronics from harsh ambient conditions and humidity.

Important Considerations (Precautions)

• Manifold Operation: Always operate 3-valve or 5-valve manifolds in the correct sequence (Open Equalizer → Close Low Pressure → Close High Pressure) to avoid single-sided overpressure shock during maintenance.
• Impulse Line Slope: Slopes for impulse tubing must be maintained (at least 1:12) to prevent trapped gas bubbles in liquid lines or condensation pockets in gas lines.
• Process Compatibility: Ensure process media (corrosive acids, chlorine, viscous fluids) aligns with chosen wetted diaphragm and fill fluid (e.g., silicone oil vs. Fluorolube).

Product Applications

• Flow Measurement: Paired with primary flow elements (orifice plates, Venturi tubes, Pitot tubes) to calculate volumetric and mass flow rates.
• Hydrostatic Tank Level: Measuring liquid levels in pressurized or atmospheric tanks using dual process connections.
• Filter Monitoring: Detecting pressure drop across industrial filtration units to trigger automatic backwashing or maintenance alerts.
• Oil & Gas / Chemical Processing: High-pressure pipeline monitoring and reactor pressure differential control.
