Oxygen sensor

City Technology has launched the 4OXV oxygen sensor which uses unique vented technology to eliminate false alarms. It moves the reliability, stability and overall performance of electrochemical oxygen sensing to a new level, enabling instrument manufacturers to offer users unparalleled confidence in the detector’s performance over the full life of the sensor, reducing costs and reinforcing trust in the technology. Relevant applications include industrial safety, oil and gas, mining, wastewater treatment and petrochemical.
 
The vented technology within the 4OXV and other significant design enhancements address the issue of sensor lifetime, reducing lead exhaustion, electrolyte leakage and inappropriate response to environmental variability – the three main causes of oxygen sensor premature failure. Rapid temperature changes experienced when taking an instrument from a temperature controlled internal environment into desert or arctic conditions, can lead to a rapid rise or fall in the volume of air entering the instrument. Without suitable correction, the differential pressure created across the sensor will cause a glitch in the output which can result in a false alarm. By introducing vented technology, the differential pressure is instantaneously corrected, eliminating the signal spikes The design of the sensor provides performance improvements in three key areas: false alarm glitch immunity; enhanced output stability and increased reliability. All of which dramatically reduce warranty costs. Other significant benefits to the end user include: Reduced instrument downtime & fault replacement, enhanced user confidence, life protection, increased operating life, measurement accuracy and backwards compatibility
