10 Gas Detection From A Basic Oxygen Sensor to a Complete Oxygen Analyser Solution


SST Sensing Ltd (UK) have been designing and manufacturing a wide range of rugged, robust and reliable Zirconium Dioxide Oxygen Sensing Solutions to the combustion and aerospace industry for over 10 years. SST’s oxygen sensors are used in fuel tank gas inerting systems in leading aircraft manufacturers, as well as the biomass boiler and gas combustion market where they are fitted to improve heating efficiency of boilers and reduce harmful emissions. Although these are the primary target markets for these products, SST oxygen sensors are suited to a large number of alternative and exciting applications due to the flexibility and capability of the sensor. The sensors can prolong the life of fruit, vegetables and other perishable goods by monitoring the oxygen levels in the storage and transportation environments. They can also be used in composting, agriculture and medical applications, to name just a few.


Following a review from customer feedback, SST has developed the product range from its simplest form (a basic sensor) into complete oxygen sensing solutions tailored to meet customers’ specific requirements. The sensor is available to purchase in various mounting styles: flange, probe, miniature and threaded. All of SST’s oxygen sensors require interface electronics in order to operate. SST can supply you with off the shelf interface electronics or, if you prefer, we can assist you in integrating the required interface components into your own system. And for those who require a low cost integrated solution, SST’s OXY-FLEX oxygen analyser combines the highly accurate Zirconium Dioxide Oxygen Sensors with complete built-in interface electronics, removing the need for customers to implement their own electronics.


Still, for many applications an “Off the Shelf” oxygen sensor is not always the right solution. Often customers require changes to physical designs, electronic conditioning, special cabling…the list goes on. SST has many years of experience in designing and customising oxygen sensors for specific applications.


The Zirconium Dioxide Oxygen Sensors are the ideal solution where reliability and accuracy are required, robustness in harsh environments is essential, ease of calibration if necessary; resistance to carbon deposits and other pollutants is vital and increasing efficiency and minimising emissions is fundamental. The dynamic sensing principle ensures failsafe operation. The rugged stainless steel construction ensures long life in aggressive and high temperature environments. No reference gas is required for these sensors and all versions are able to measure a wide oxygen range.


SST combines their high quality sensors with excellent customer service and technical support, ensuring the needs of their customers are met quickly and accurately. Reader Reply Card No. Leading Innovation in Gas Detection


The demands on gas detection equipment manufacturers have become more stringent with a greater focus on performance, reliability and user-friendliness. As a result, manufacturers look to their sensor suppliers to sustain their competitiveness and to provide robust and sensing solutions for life critical applications.


For many years, electrochemical sensors have been used to measure toxic and oxygen depletion hazards with great success. However traditional sensor designs are constrained by the technology itself, requiring reservoirs of corrosive electrolyte to support performance in extremes of temperature and humidity. This necessitates larger sensor designs which have an impact on the minimum size of the gas detectors using them.


Solidsense (Germany) is a pioneering manufacturer of electrochemical gas sensors based on a unique solid electrolyte design. Available for carbon monoxide, hydrogen sulphide, nitrogen dioxide and hydrogen as well as long life oxygen, our products provide reliable and accurate gas sensing in a package no bigger than an average thumbnail. Boasting excellent environmental stability, fast response and accurate measurement they provide instrument manufacturers with a sensing solution to meet their customers’ needs now and in the future.

Sensor/Transmitter for Combustible Gases


The EX-6100 from Enmet (USA), is a 24 VDC, Combustible Gas Sensor/Transmitter and utilises a matched pair of catalytic elements. The sensor can be calibrated for 0-100% LEL hydrogen, methane, propane, butane or other combustible hydrocarbons. The EX-6100 is standard with an internal alarm relay PC board, two inlet/outlet parts, and plug-in sensor. Other features include a liquid crystal display, 4-20 mA output and non-intrusive calibration. Options include a weather guard and remote sensor. The EX- 6100 provides a 4-20 mA output signal, and requires 24 VDC power from a PLC or various model controllers available from Enmet. The EX-6100 is certified to international standards.

(%LEL), Oxygen (% O2), and toxic gases (ppm).


Industrial Scientific’s recent growth can be attributed to iNet – the company’s Gas Detection as a Service solution. iNet is a software-based service that solves common challenges faced in gas detection programs related to the maintenance of gas detector fleets and the lack of visibility into instrument alarms, exposure and usage. Today, there are more than 70,000 gas monitors operating on iNet at worksites around the world.
