This product joins Yokogawa’s existing lineup that includes the in-situ TDLS8000 and probe type TDLS8100/TDLS8200.
Built upon Yokogawa’s second generation of TDLS analysers with improved reliability, quick response time, and reduced maintenance, the TDLS8220 is a direct replacement for the first-generation TDLS220.
The original platform of the TDLS200 was developed because of a US Department of Energy (DOE) programme titled in-situ sensors for the chemical industry. The product was released in 2005 and achieved success in many different process applications and in a variety of industries, with over 1500 units sold worldwide.
The TDLS8220 is being introduced to complement Yokogawa’s existing TDLS product lineup by satisfying the need for extractive oxygen measurements where in-situ or probe-type installations are not applicable and where traditional technologies fall short.
The TDLS8220 laser module and detector module are now encompassed in one board set, but still retain a reference cell for improved reliability of absorption peak detection. In addition, the auto gain function automatically optimises detection sensitivity during dynamic process events. Due to the non-contact measurement, sample handling system upsets or failures won’t damage the analyser sensor. The TDLS8220 plays a key role in ensuring accurate and reliable oxygen measurements for safe continuous operation.
The unique flow cell design features a tube-in-shell construction that allows tight temperature control of extractive samples at the desired set point. The analyser does not require consumables, and solid-state technology eliminates the need for routine calibration. The TDLS8220 supports field serviceability with onboard diagnostics and 50 days of data and spectral storage to identify and correct minor issues before they turn into serious problems.
