SETNAG - EXPERT EN ANALYSE D'OXYGENE - The oxygen analysis people

MicroPoas® is a sensor with a built-in metal reference, meaning that it does not require any reference gas. This gives several advantages: miniaturization, autonomy towards outside environment, high metrological performances, use in extreme environments (extreme temperature and pressure), longer life span, etc. Mastered technique and technology Miniaturization: the smallest of all zirconia sensors - standard diameter: 3mm (2mm for special application) - 10mm long Autonomy: very high measurement accuracy - Specific to gaseous oxygen - Inside metal reference: made of a metal and its oxide, it is placed inside the zirconia sleeve - Built-in thermocouple (K or S type): the real MicroPoas® temperature is taken into account. Unique features - Reference gas becomes unnecessary - Very high resistance to thermal shocks - Longer life span - Assemblies fit...

Measurement of oxygen in combustion gases and in incineration gases. QAL1 compliant (EN14181) Brand : SETNAG ADVANTAGES No need for reference gas: use of the MicroPoas® Maximum gas temperature: up to 1300° C continuously, depending on the version No sensitive parts and no hot spot inside the duct Free circulation of the gases you analyse "Detachable" probe tubes: easy to dismantle and replace for simple and cost-effective maintenance. Limited maintenance and service operations: easy probe tube cleaning with compressed air and/or fast dismantling. MEASUREMENT PRINCIPLE The gases own speed inside the duct enables them to flow freely up to the sensor where they are analysed. They pass through co-circular tubes the length of which can be adapted to the dimensions of the duct. The electronic system collects the temperature and voltage signals from the MicroPoas®, and gives the oxygen concentration. EXAMPLES OF APPLICATIONS Control of combustion in power generation, district heating...

In situ oxygen probe Brand : SETNAG ADVANTAGES : Excellent response time, thanks to the MicroPoas® miniaturized zirconia sensor. Increased reliability and easy set-up as no reference gas is required. The excellent measurement reproducibility ensures perfect control of your process. MEASUREMENT TECHNIQUE / RUNNING The TTH sensor is directly plunged in the gases for analysis. TTH can be used from 500 to 1050°C depending on the model. The MicroPoas® signals are collected by one of our electronic systems (ATS2020 or Oxybox’Air) which will display and/or send a 4-20mA output signal proportional to the measured oxygen concentration. EXAMPLES OF APPLICATIONS Heat treatment Control of combustion Waste incineration Crematorium

Analysis and measurement of trace oxygen inside pure and inert gases Brand : SETNAG ADVANTAGES : Wide measurement range: from 0.01ppm to 25% over a single range Easy set-up and fast response time: use of the MicroPoas®. Simple and user-friendly system Almost maintenance-free Alarm monitoring as standard MEASUREMENT TECHNIQUE The gas freely flows in the analyser (it can also be forced) and passes over the MicroPoas®. Thanks to the built-in metal reference of our zirconia sensor; measurement is in no way influenced by the environment. Therefore, reliability and reproducibility are improved. EXAMPLES OF APPLICATIONS Air separation Control of particular atmospheres Tightness control Heat treatment Control of inerting JC24V

The oxygen pump gauge has been designed to generate and control atmospheres containing oxygen Brand : SETNAG ADVANTAGES Continuous measurement of the generated atmosphere between 10 -35 and 0.25atm Use of different kinds of carrier gases, at various concentrations Limited costs as a single gas is required Very high measurement accuracy: use of the MicroPoas® Low gas consumption: necessary flow 1 to 13 l/h Control of the applied voltage and current Maintenance-free MEASUREMENT TECHNIQUE The oxygen pump set uses the principle of ionic conduction of zirconia. When a continuous voltage is applied across the zirconia tube terminals an oxygen flow is created. The quantity of oxygen in the gas circulating inside the zirconia tube will increase, or decrease, according to how the voltage is applied. The partial pressure is measured by the MicroPoas™.

Oxygen partial pressure measurement Brand : SETNAG ADVANTAGES Wide measurement range: from 10 -35 to 0.25atm. Excellent response time thanks to the MicroPoas® miniaturized zirconia sensor. Easy and fast set-up MEASUREMENT AND WORKING TECHNIQUE The reactional mixture to be analysed freely circulates through the analyser, and the MicroPoas® delivers a signal which reflects the equilibrium oxygen partial pressure in the gas. Jok’Air-2060 can measure from 10 -35 to 0.25atm. EXAMPLES OF APPLICATIONS Materials characterization Nuclear research
