The LuminOx Flow-Through Optical Oxygen Sensor Allows For A Clean Gas Sample Stream Directly Into The Sensor Which Can Be Completely Removed From The Process Environment.
The LuminOx Flow-through Optical Oxygen Sensor is developed and manufactured by SST, it is part of the LuminOx family, which is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of fluorescence quenching by oxygen, also known as luminescence quenching.

The LuminOx Flow-through Optical Oxygen Sensor (LOX-02-F) is an extension to the standard range of LuminOx oxygen sensors. The original LOX-02 sensor was designed to be completely immersed in the sample gas environment as the base of the sensor is not gas-tight.

The flow-through housing style is sealed on the base which allows for a clean gas sample stream into the sensor which can be completely removed from the process environment. A flow-through housing allows for better sample gas management and options in terms of where the sensor can be situated.

The patented technology allows SST to produce a range of sensors that are based on a non-depleting operating principle. This can contribute to the LuminOx sensors having a comparably longer lifetime that other competitor technologies, such as galvanic sensors, for similar applications.

LuminOx oxygen sensors each have an internal sensor for temperature and barometric pressure compensation, meaning the customer does not need to consider this in their design. It also communicates directly to the customer’s USART so no signal conditioning circuitry is required.

LuminOx is a completely solid state sensor and contains no lead or liquid electrolytes. It is therefore 100% RoHS compliant. It also has virtually no cross sensitivity, allowing it to be used in applications where other technologies are unreliable due to the particular mix of gases present.

The luminescence quenching principle measures the partial pressure of oxygen (ppO2). The internal barometric pressure sensor measurement along with ppO2 measurement allows an oxygen concentration (O2%) value to be calculated. The USART output allows the sensor to communicate the values of O2%, ppO2, barometric pressure, internal temperature and a sensor status.

 

The LOX-EVB LuminOx Evaluation Interface Board is designed to allow customers to quickly and easily evaluate SST’s range of optical oxygen sensors with the minimum of effort or design work.

Developed and manufactured by SST, the LuminOx family is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of fluorescence quenching by oxygen.

The LOX-EVB offers customers the ability to test the LuminOx sensors with ease. The interface simultaneously provides three outputs; RS232 (serial interface voltage levels); RS485 (Modbus RTU) port allows multiple sensors to be addressed on a bus; 0-5V analog output for basic measurements of oxygen only.

The LOX-EVB LuminOx Evaluation Interface Board converts the LuminOx TTL level RS232 output into 3 standard industrial outputs and it auto detects ppO₂ or O₂% variants of LuminOx sensor.

The low cost, low power and long life are what differentiates the LuminOx Optical Oxygen Sensors from other oxygen sensors.

Developed and manufactured by SST, the LuminOx family is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of fluorescence quenching by oxygen. Oxygen sensing using this sensor enables oxygen concentration to be calculated.

The patented technology allows SST to produce a sensor that provides low power operation, while offering a much longer lifetime than electrochemical and galvanic sensors.

The LuminOx Optical Oxygen Sensors are internally temperature compensated meaning the customer does not need to consider this in their design. It also communicates directly to the customer’s UART so no signal conditioning circuitry is required.

LuminOx is a completely solid state sensor and contains no lead or liquid electrolytes. It is therefore 100% RoHS compliant. It also has virtually no cross sensitivity, allowing it to be used in applications where other technologies are unreliable due to the particular mix of gases present.

LuminOx measures the partial pressure of oxygen (ppO2) which, along with the internal sensor temperature is communicated serially to the host microcontroller. LuminOx is also available with an internal barometric pressure sensor. This enables oxygen concentration (%O2) to be calculated and transmitted, along with the ppO2, temperature and barometric pressure.

The LuminOx Sealed Optical Oxygen Sensor Range Offers Users With Application Requirements To Only Measure Sample Gas At The Front Face Of The Sensor.

The LuminOx Sealed Optical Oxygen Sensor is developed and manufactured by SST, it is part of the LuminOx family, which is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of luminescence quenching.

The LuminOx Sealed Optical Oxygen Sensor (LOX-02-S) is an extension to the standard range of LuminOx oxygen sensors. It is a similar diffusion type sensor like the original LOX-02 sensor. However, the LOX-02-S has a sealed base that is gas-tight, meaning only the face of the sensor with the protective membrane needs to be in the sample gas environment, externally leaving easy access to the pins of the sensor.

The patented technology allows SST to produce a range of sensors that provides low power operation, while offering a much longer lifetime than electrochemical and galvanic sensors.

The sensors each have an internal sensor for temperature and barometric pressure compensation, meaning the customer does not need to consider this in their design. It also communicates directly to the customers USART so no signal conditioning circuitry is required.
