In-Situ Gas Analyzer TDLS8000

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

Your 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.

Features: Reasons for high reliability

Enable for safe operation, safety level SIL2, and explosion proof standards.

It conforms to the certification of the safety level SIL2 in accordance with the International standards IEC61508, and can also conform to the SIL3 by duplexing the analyzer.
In addition, the solid body conforms to various explosion proof standards of the area-segmented Zone2/Div2 or Zone1/Div1 and can be installed in dangerous places.

No PC is required for direct simple operation and maintenance with intuitive 7.5-inch color touch screen HMI.

It supports 10 languages: English, German, French, Spanish, Portuguese, Russian, Hungarian, Korean, Chinese, and Japanese.
Provides all information, including trend graphs, and can be remotely installed.

Standard communication functions that can be checked and adjusted both on-site and at remote locations. (Installation and maintenance cost reduction)

The HART and Modbus TCP communications standards are standardized and can be setup and adjusted by our FieldMate.

Fully field repairable with 50 days of data and spectra storage

Data for 50 days are stored, and can be analyzed when installed in the process.

Compact design for one-man installation without sacrificing ruggedness

Modular design allows replacement and re-operation of components at the site

System configuration according to the plant situation

System configuration according to the plant situation
By connecting to FieldMate via standard HART communication, setting and adjustment can be easily done without HMI. A small display is standard equipment at both ends (sensor control unit and laser unit). The transmittance required to adjust the light axis is always displayed, making it easy to adjust the light axis.

System Configuration with HMI
The 7.5-inch color touch screen HMI YH8000 can improve on-site monitoring and operability.

Multi Analyzer Configuration with Remote HMI
Up to 4 TDLS8000 can be connected per HMI for remote control.

IF8000:
The Process Insulation Flange protects the TDLS8000 from process gas pressures, heat, dust, and corrosive components from the process gas.
It can be used for protection during direct mounting or bypass mounting.

Use in the following cases.

• When the process gas pressure exceeds 500 kPa
• If the temperature of the process is high and the temperature of the process window exceeds 55℃ even if the process window is purged.
•  If the process has a large amount of dust and the process windows are purged to prevent dust from adhering to the process windows or corrosive components from entering the process windows.

YC8000 Flow Cell : Used to sample and measure gases at any location.
Calibration cell : Used for offline calibration and validation.
Unit connection cable : Used to connect the sensor control unit and the laser unit.

In this way, we are making use of our products.

O₂ and HCl measurement at waste incinerators
Since this is a non-contact measurement, the measurement of exhaust gas from waste incinerators, which have a large amount of dust and corrosive components, is not problematic with TDLS™. In addition, since measurement can be performed at high temperatures, measurement and high-speed control can be realized in the vicinity of the combustion section, thereby improving the operating efficiency.

    Real-time O₂ Measurement at Garbage Incinerators Improves Combustion Efficiency and Reduction in NO_x and CO

O₂ was measured for safety and quality control at chemical plants and steel works.
The TDLS eliminates the problems of maintaining sampled filters, delaying responses, and interfering gases.

O₂ and CO were measured to monitor the fire prevention of coal and pulverized coal storage.
Temperature and CO-measurements are essential for detecting the ignition of coal and bag filters in storage tanks.
The reference cell can stably measure low concentrations, which were Display at 0% in other products. High-speed measurement is possible without concern of dust clogging.

H₂O measurement for various moisture monitoring.
Measure the water content of the drying oven, such as cellophane, gypsum, plywood, paint, and food, from the % level of water to the ppm level of water in the manufacturing process, which is unpleasant.

O₂ and CO were measured in an electric furnace.
It is possible to measure the O₂ and CO of the exhaust gas generated in the electric furnace and perform melting without waste.
Exhaust gas from high-temperature and high-dust electric furnaces has proven to be an installation method to suppress the effects of the exhaust gas, and can be measured without problems.

Flow to Order

This is a basic flow, although it differs depending on the customer's area and plant.
For details, please contact us without concern.

*Please tell us about the status of the plant in order to propose the best specifications for your application.
The items related to the status of the factory are as follows.

• Application
• Setting conditions, Optical path length
• Gas pressures, Temperature
• Dust amount
• Gas composition (Measurement range and Gas concentration)

Maintenance Flow

Return to the repair shop is unnecessary during maintenance. Parts can be replaced at the site and restored immediately.
* Since the TDLS is equipped with a self-diagnosis function and supports predictive maintenance, sudden stop of the plant can be avoided in principle.
