Overview

The new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements, eliminating the need for sample extraction and conditioning. The non-contacting sensor allows for a variety of process types including corrosive, abrasive, and condensing.

The first generation platform has been proven in many others for the measurements of O2, CO, CH4, NH3, H2O and many more NIR absorbing gases. This second generation platform has improved reliability and ease of installation and maintenance while still meeting or exceeding designed application demands.

Analyzer that realizes real-time feedback and adds value to users through active use such as process control and safety control
* Energy-efficient furnaces, etc., and safety and stable operation contribute to improving OPEX and reducing environmental impact.
* Rapid feedback of process output to the control program, which is essential for optimal operation.
* Release of cumbersome sampling devices and drive components from maintenance.
* Realization of direct measurement under severe process conditions such as high temperature and corrosiveness.
The TDLS8000 is an analyzer that can solve these problems.

The most trusted laser analyzer designed specifically to meet all of your requirements in one robust device that is easy to operate and maintain.


Features


SIL2 TruePeak combined with smart laser Technology
Intuitive touchscreen HMI
HART and Modbus TCP communications standard
8-stage auto-gain adapts to difficult applications
Fully field repairable with 50 days of data and spectra storage
Compact design for one-man installation without sacrificing ruggedness
Area classification Zone2/Div2 or Zone1/Div1

Benefits


* Measurement with a line using a laser does not miss dangerous thermal unevenness.
* By using a reference cell, low concentration gas is also measured with high accuracy.
* The optical path length can be measured up to 30 m and can be measured up to 1500℃ of hot gas.
* It can also be installed in dangerous places by acquiring Japanese explosion proof authentication, IECEx certification, ATEX
certification, FM (US, Canada), KOSHA certification, NEPSI certification, and EAC explosion proof certification.
* The sampling device is unnecessary, and it is easy to install because of its compact design.
* Non-contact type sensor without consumables, i.e. maintenance due to leakage or deterioration is unnecessary.
* It is possible to replace the parts on the spot while they are still installed during repair, and it is possible to reduce the
plant shutdown and repair costs due to downtime.
