City Technology launches long life oxygen sensor

Oilfield Technology,


Honeywell company, City Technology, has launched the new 4OxLL, a long life oxygen sensor designed to work for the whole life of the average portable gas detector.

Oxygen sensors working in safety critical industrial applications must deliver high performance detection and fast speeds of response; lives and assets depend on consistent, accurate readings. Many plants feature harsh process conditions and environmental extremes and transients that can compromise stability, so a robust design with a quick recovery time is essential.

Cost reduction is a key factor in sensor selection in today’s competitive world. Many plants use thousands of oxygen sensors in their portable gas detector fleets, so ongoing maintenance and sensor replacement costs can soon mount up. Field failures can also have an adverse cost impact, resulting in unnecessary process downtime and safety risks. The industry ideal is a sensor that can work as long and hard as the instrument itself, in all conditions that it might face.

City Technology’s new 4OxLL oxygen sensor delivers high value through a variety of features. With an operational life of five years, the average life of a portable instrument used in safety critical industrial applications – 4OxLL provides a fast speed of response with less than 5% drift over life. It’s innovative design and unsurpassed performance in environmental extremes and transient conditions, also minimises nuisance alarms and the occurrence of field failures.

4OxLL dramatically reduces ongoing maintenance by removing sensor replacement costs. A plant operating 200 portable gas detectors, can save 200 hours of maintenance labour (US$ 20 000 in total, based on US$ 100/hr labour), over five years, compared with a standard two year life model. The combination of its performance and cost saving potential makes 4OxLL ideally suited to diverse industrial safety critical monitoring applications.

John Warburton, Strategic Marketing Manager for City Technology, comments: “Using a high stability solution like 4OxLL enhances safety and provides attractive operational efficiencies. We used advanced component design, finite element method modelling (FEM) and Six Sigma, to create a robust and highly reliable design. FEM allowed us to simulate the distribution of oxygen within the sensor under a range of environmental conditions and predict key performance parameters such as sensor output, start up characteristics and transient response so enabling us to design the most robust sensor possible. 4OxLL features ‘oxygen pump technology’, which unlike conventional galvanic sensors, has no consumable anode (the life limiting element of an oxygen sensor). This delivers the long life performance our customers and end users require”.
