City Technology is introducing a new oxygen sensor to its industry-leading gas sensing range.
The new 4OxLL long-life oxygen sensor will be launched by Honeywell company City Technology at the upcoming QME Mining Show being held in Queensland, Australia from 22nd to 24th July. The new gas sensor will be showcased at the Honeywell Life Safety booth A275.
Mining companies are constantly facing the challenge of protecting their workers in underground mines from oxygen depletion and toxic and flammable gases. Companies must not only maximise safety, adhere to stringent regulations and protect their people and assets, but also leverage operational cost efficiencies, which can be achieved by selecting the right gas sensing solution.
City Technology’s new AN/NZS 4641 compliant 4OxLL oxygen sensors deliver advantages such as excellent stability in challenging environmental conditions, minimised nuisance alarms and extended operational life.
Mario Moura, Marketing Director for Honeywell Life Safety explains that improving the reliability of gas detectors in underground mines at reduced cost of ownership was a key driver in the sensor’s introduction in the Australian market.
According to Mario, mining environments can be extremely challenging for portable gas detectors with nuisance alarms occurring due to fluctuations in temperature and relative humidity as workers move from external locations into hot and humid mining environments; pressure shocks can also occur during mine shaft lift descent resulting in incorrect oxygen readings.
Sensor performance is a major factor in the reliability of a portable gas detector; only the highest performing sensors can be used to address the safety concerns created by flammable and toxic gases and depleted oxygen levels in underground mines.
The new AN/NZS 4641 compliant 4OxLL oxygen sensor is the result of more than 35 years of experience serving the mining industry. A pioneer of mining sensing solutions, City Technology offer several products that raise the global industry standard including the 4CM carbon monoxide sensor designed to meet the Chinese Mining Specification, AQ6205-2006, the world’s most challenging mining standard.
City Technology’s latest product, the 4OxLL incorporates a unique, patented Electrochemical Cell (ECC) internal geometry designed using Six Sigma and FEM modelling practices and manufactured to exacting standards. The oxygen sensor’s revolutionary component design can withstand changing humidity and temperature conditions, ensuring accurate readings.
The 4OxLL also offers modern mining operators attractive cost efficiencies in addition to enhancing safety and ensuring maximised device uptime. The 4OxLL dramatically reduces ongoing costs as it is designed as a five-year solution, lasting as long as the operational life of a typical portable gas detector, when most oxygen sensors last approximately two years. This longevity reduces maintenance costs considerably, with no need for sensor change out while its patented design helps to extend calibration intervals, delivering further cost reductions.
