Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.
Yokogawa offers a full range of product solutions including an industry leading zirconia oxygen probe series, as well as a line of cutting edge tunable diode laser spectrometers.
Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negates the need for sample extraction and conditioning.
The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process.
The AV550G Multi Channel Oxygen Analyzer System allows for measurements on up to eight ZR22 probes simultaneously. The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling, reducing maintenance costs and resulting in faster measurement response to changes in the process.
The ZR202 transmitter/detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ humidity measurement.
The OX400 is a low level zirconia oxygen analyzer that is capable of measuring a wide range of concentrations, from 0-10 ppm up to 0-100 vol%O2.
The TDLS220 is specifically designed for accurate, reliable and low maintenance measurement of volume percent (vol%) oxygen (O2) for safety and process applications. It is a viable alternative to paramagnetic O2 analyzers.
Yokogawa's Zirconia oxygen detector systems offer a variety of calibration units for quick, easy control of calibration gases giving the user simple, accurate calibration.
WZ-H cables are compatible with all ZR22, ZR402, and AV550G model Oxygen Analyzer Systems. The purpose of these cables is to transmit the signal from the sensor/detector to the analyzer. Additionally, the cabling provides for electrical input to the heater assembly within the detector for cell temperature control.
The accumulation of fly ash on the zirconia cell affects its ability to measure oxygen concentration. Fly ash and its constituents can reduce the life of the zirconia cell and affect the cells response time to changes in gas concentration. Yokogawa's large surface area sintered metal filters are designed to keep particulate and ash off the measurement cell.
Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants.
Yokogawa’s new TDLS8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate 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.
