Why use a TDL sensor for measuring oxygen?

TDLs have many advantages over other oxygen measurement technologies. Firstly, they are installed in situ in the process pipe or vessel so are exposed directly to the gas and therefore measure immediately. Some other analyzers measure a sample of gas that has been extracted and conditioned, which takes time and increases risk. Secondly, TDLs are immune to the presence of other gases in the process and will only measure oxygen. Thirdly, they are extremely reliable and require practically zero maintenance.


Are TDL oxygen sensors easy to install?

Sometimes. Once the insertion point has been selected it’s a matter of fitting one or two flanges and a temperature and pressure sensor. Most TDLs are of a cross-stack design, meaning that they’re comprised of two parts (laser source and receiver) that sit opposite each other in the pipe or vessel. The two units have to be very carefully aligned which can be problematic. The GPro 500 has both parts installed in the same unit. The laser source is reflected by a three-sided mirror and is directed back to the receiver. Therefore, no alignment is required. Watch our video on easy Installation.


How can an oxygen TDL reduce costs?
Unlike other gas measurement technologies, TDLs have a very low maintenance requirement. Once installed they will run reliably for many months without needing any maintenance. When used in combustion processes they can ensure the fuel/air mixture is exactly right and can reduce fuel costs by thousands of dollars. For more information check our Payback Calculator.


In which applications can TDLs be used?

TDLs have a wide range of applications, including process control in direct chlorination and oxy-chlorination; safety monitoring in VCM waste gas recovery; and combustion optimization in package boilers, thermal oxidizers, fired heaters, FCC units, etc. For more information check our Apllication eBooklet.
