METTLER TOLEDO's GPro 500 Series Tunable Diode Laser Gas Sensor

The use of Tunable Diode Laser (TDL) gas sensors is becoming more and more common in industrial processes. This is because they measure directly in the process gas stream without drift or cross-interference and are far more economical to purchase, install and maintain than other gas analyzer types. TDLs use a measurement technology called absorption spectroscopy: they output a beam of laser light at the same frequency that the gas to be measured absorbs light. The TDL analyzes the light after it has passed through the gas stream and calculates the quantity of the target gas in the stream.

Most TDLs are comprised of two parts: the laser source unit and a receiving/analyzing unit. These parts must be installed directly opposite each other, which is not always easy and misaligned can often occur. METTLER TOLEDO's GPro 500 Series solves this by combining both parts in a single unit. A probe attached to the GPro 500 sensor protrudes into the gas stream. A three-sided mirror at the end of the probe directs the beam back through the probe to the receiver, so alignment is always perfect.

The series is available with a wide range of different probes and adaptions that allow the GPro 500 to be placed wherever required in a process. These include: 

• a probe with a filter to prevent dust ingress
• a wafer probe for narrow (2") pipes
• an extractive cell for use with sampling and conditioning systems
• a White cell for trace level detection

Using a modular design, the GPro 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂). 

The GPro 500 does not require maintenance-prone extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.

Intelligent Management for Process Sensors

Process analytical sensors can require scrupulous levels of attention and maintenance to continually deliver optimum performance. In some cases, overly frequent or involved maintenance is performed in order to avoid problems. Mettler Toledo, globally recognized leader in the development of process analytical sensors, developed a solution to streamline sensor maintenance and maximize reliability and performance.

The iSense software suite supports Mettler Toledo's line of intelligent sensors, monitoring and documenting sensor performance while maintaining real time indications of time to maintenance and calibration. Essentially, the iSense software provides guided sensor maintenance and continually verifies the operational health of the sensor to assure that delivered data is accurate and reliable.

There is much more to learn about how the iSense software and comprehensive offering of intelligent sensors can enhance process performance, as well as the efficiency of analytical operations. Reach out to a process analytics specialist with your analytical measurement challenges. Combining your process knowledge and experience with their product application expertise will yield an effective solution.
