SafeTap II

Description

SafeTap II Retractable Optical Oxygen Sensor

Product Overview

The Barben Analytical SafeTap II is a retractable or “hot tap” Optical Oxygen Sensor. It is used with the OXYvisor Oxygen Analyzer for in situ sampling methods. Designed for use in liquids and dry or wet gases, the SafeTap II can be manually inserted and retracted from the process line. The SafeTap II provides the capability of in situ installation of a selectable BOSx Oxygen sensor ranges into the process pipe or vessel.

Features and Benefits

• Uses optical quench luminescent technology: no cross-sensitivity to CO₂, SO₂, NH₃, and H₂S, not affected by high O₂ levels and moisture.
• Eliminates sample handling systems in extractive sampling.
• Reduces installation costs, complexity, and maintenance.
• Adjustable sensor insertion length for various pipe diameters.
• Integrated RTD at sensor tip for accurate temperature measurement and compensation.
• Optional pressure transmitter for accurate in-line pressure compensation of O₂ measurement.
• Quick and easy sensor cap replacement.
• Approved for Hazardous Location installations

Typical Applications

• Biogas – wet digester gas. Compatible with typical stream compositions CH4, CO2, H2O, H2S, N2, O2, NH3 & H2
• Biogas – H2S removal/sweetening, amines or bio scrubber
• Renewable Natural Gas (RNG) – upgraded biomethane trace O2 (ppm) measurement for transmission quality pipeline gas
• Carbon capture processes in CO2 (trace and % level O2)
• General replacement of E-Chem (electrochemical) cells for Trace O2 ppm to % O2 level measurement

Typical Installations
