FOXBORO P0400DL pH Sensor

Description

FOXBORO P0400DL pH Sensor

Product Dimensions：

Foxboro pH Sensors (by Schneider Electric) are heavy-duty industrial electrochemical sensors engineered for precise liquid analytical measurement across harsh process conditions. Notable lines include the PH10 Dolphin Series, PH12 Series, and 871PH Series.

Product Detailed Description

Foxboro pH sensors measure hydrogen ion activity in aqueous solutions to determine acidity or alkalinity. Designed with robust double-junction reference electrodes, high-purity glass membranes, and integrated RTD temperature compensation, these sensors interface directly with transmitters like the Foxboro 875PH or 876PH for automated process control.

Key Technical Parameters

Key Advantages

• Flat Glass Option: Minimizes fouling, coating, and abrasion in high-solids or slurry applications.
• Double Junction Reference: Resists poisoning from heavy metals, sulfides, and cyanides.
• High Chemical Resistance: Robust PEEK and PVDF body construction tolerates aggressive acids, bases, and organic solvents.
• Smart Technology (pH12/871PH): Sensor memory stores calibration data, allowing pre-calibration in lab environments before field deployment.

Important Considerations (Precautions)

• Never Allow Drying Out: Keep the glass measuring bulb wet during storage using a 4.0 pH buffer solution; drying damages the hydrated gel layer.
• Regular Cleaning & Calibration: Clean organic or inorganic build-up using mild solvents or dilute HCl, followed by a two-point buffer calibration (pH 4, 7, or 10).
• Flow Velocity Limits: Avoid installing directly in ultra-high-velocity streams to prevent glass erosion and signal noise.

Product Applications

• Chemical Processing: Neutralization tanks, reactor vessel monitoring, and acid recovery.
• Water & Wastewater Treatment: Influent/effluent monitoring, flocculation control, and discharge compliance.
• Pulp & Paper: Bleach plant monitoring and stock preparation.
• Power Generation: Boiler feed water treatment and cooling tower water monitoring.
