The SST Philosophy is to deliver the required sensing and control solutions to their customers which exactly meet their technical and commercial sensor requirements.
Achieved through our standard range of sensors or providing customer specific sensor solutions, SST have been designing and manufacturing fluid and gas sensing solutions for over 15 years. Where a specific solution is required, SST Sensing Ltd will identify the suitable technology and use this as a building block to provide a bespoke customer solution.
Their technical department is comprised of highly experienced and qualified engineers who work extensively with our customers to ensure their requirements are met. Engineers work with customers to provide full application and technical support if required.
SST now has over 60 employees and our success is growing day by day. The core of this success is due to our strong commitment to their customer
As an ISO 9001:2015 certified organisation, SST manufacture, design, customise and configure a range of sensors and switches for gases and liquids.
Within their vast range of standard product offerings you will find; miniature, solid state optical liquid level switches; rugged, robust and reliable Zirconium Dioxide oxygen sensors; factory calibrated optical oxygen sensors that measure ambient oxygen levels and finally carbon dioxide sensors which are powered using energy harvesting technology
SST understands that customer needs vary and can be very specific. SST’s application engineers work directly with our customers’ engineers to provide application and technical support. SST have the in-house ability to take any of our standard range of sensors and customise it to your exact specification if the standard spec is unsuitable. Whether that be adding or modifying electronics and software, changing outputs, adapting housing or thread styles, adding cabling, connectors or environmental protection.
ACE Analytical with SST aim to solve customers' problems by providing excellent products coupled with full application and technical support.
Gas Analysis Probe (GAP)
Designed for monitoring of oxygen content within flue or stack gases, the GAP has relays, analogue and Modbus outputs along with pressure and temperature compensation making it a complete analyser for combustion optimization and burner/boiler trim applications.
A compact zirconium-oxide analyser to efficiently monitor excess air in combustion processes. The probe is manufactured from 316 stainless steel and can handle sample temperatures up to 700°C with an insertion length of 435mm (17.126″). The sample is extracted to the sensor chamber and returned to the flue via the Pitot effect, so there is no need for instrument air. The analyser operates without the need for an air reference.
Designed with ease of maintenance in mind. The GAP’s user replaceable sensor can be cleaned or replaced in seconds.
OXY-Flex Oxygen Analyser
The OXY-Flex Oxygen Analyzer is suitable for measuring in oxygen closed systems, such as ventilation pipes and boiler exhaust flues.
The OXY-Flex Oxygen Analyzer is designed to measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400⁰C. The oxygen analyser employs a well proven, small zirconium dioxide-based element at its heart and due to its innovative design does not require a reference gas. The oxygen sensor element is mounted in the tip of the stainless-steel probe and is protected by a sintered stainless-steel cap.
The OXY-Flex Oxygen Analyzer uses a unique closed loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures.
The OXY-Flex can be configured to output measuring ranges of 0-25% O₂ or 0-100% O₂. The entire measurement range is linear in both cases. The outputs can be configured to either 4-20mA and 0-10Vdc outputs or an RS232 serial communications interface.
Typical applications include; combustion control of industrial boilers, burning oil, gas, coal or biomass; incubators; composting probes and welding equipment.
Zirconia Oxygen Sensor System
The Zirconia Oxygen Sensor System offers a complete solution, removing the need for customers to develop their own electronics. Frequently used in combustion control systems, burning coal, oil, gas and biomass and in oxygen generation systems.
The Zirconia Oxygen Sensor System consists of SST’s fast response (<4s T90) zirconium dioxide (ZrO₂) screw fit sensor in conjunction with the OXY-LC oxygen sensor interface board.
The system employs a well proven, zirconium dioxide element at its heart and, due to its innovative design, does not require a reference gas. This, along with its rugged stainless-steel construction means the sensor can be used in extreme temperatures and aggressive environments.
These oxygen sensors use a unique closed loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated, providing an immediate warning of any failures.
The sensor is housed in a short probe with an M18x1.5mm thread, making installation quick and easy. The oxygen sensor can operate in temperatures ranging from -100°C to 250°C and has a lifetime of up to 10 years (depending on the application).
When connected to the OXY-LC interface board, the zirconia oxygen sensor can measure oxygen concentrations of 0.1% to 25% and 0.1% to 100%.
