Oxygen Sensor: Pressure Rating Up to 10 bar, IP Rating IP67

Q: How often should beverage oxygen sensors be calibrated?

Industrial oxygen sensors in beverage applications typically require calibration every 3-6 months depending on usage intensity, with zero-point calibration recommended weekly using nitrogen gas and span calibration using certified oxygen standards.

Q: What maintenance is required for oxygen sensors in deoxygenation systems?

Regular maintenance includes membrane inspection/replacement every 6-12 months, electrolyte refill for electrochemical sensors, optical window cleaning for optical sensors, and verification of seal integrity to prevent liquid ingress.

Component Specifications

Definition

An industrial-grade oxygen sensor is a critical component in Automated Beverage Container Deoxygenation Systems that continuously measures dissolved oxygen levels in liquid beverages during packaging. It employs electrochemical or optical sensing technology to detect oxygen concentrations in parts-per-billion (ppb) ranges, providing feedback to control systems that maintain optimal deoxygenation levels to prevent oxidation and extend shelf life.

Working Principle

Operates on electrochemical cell principles where oxygen molecules diffuse through a permeable membrane into an electrolyte solution, causing a redox reaction at electrodes that generates a measurable current proportional to oxygen concentration. Advanced versions use optical fluorescence quenching where oxygen molecules interact with a luminescent dye, reducing fluorescence intensity in relation to oxygen partial pressure.

Materials

Zirconium oxide ceramic sensing element (for high-temperature applications), platinum electrodes, polymer electrolyte membranes (Nafion), stainless steel 316L housing, fluoropolymer seals (Viton/FKM), gold-plated electrical contacts, tempered glass optical windows (for optical sensors)
