High-temperature class-leading oxygen
analyser
Following the success of the Servomex 2200 oxygen analyser for process applications, Servomex is launching a new version of the transmitter that is suitable for use with sample temperatures up to 110C
Following the success of the Servomex 2200 oxygen analyser for process applications, Servomex is launching a new version of the transmitter that is suitable for use with sample temperatures up to 110C Designated the Servomex 2200H, the high-temperature transmitter offers potential savings in installation and operating costs for the sampling system by eliminating the need to condense the hot sample prior to analysis

Process oxygen analyser has Ethernet communication
Servomex is introducing the option of Ethernet communications for its Servomex 2200 process oxygen analyser, which is still certified for use in hazardous areas
As with the 2200 model there is no need for either a purge gas or reference gas, which results in further significant cost savings, whether the analyser is being used in a new installation or as a replacement.
Fully approved for use in ATEX category 2 applications, the T3-rated 2200H is certified as flameproof to EExd, intrinsically safe to Exia, sealed to IP66/NEMA 4X, and conforms with the requirements of EN 50104 (Electrical apparatus for the detection and measurement of oxygen: performance requirements and test methods).
Other approved versions of the 2200H such as FM, CSA, and CPA will be available by Q3 2004.

Servomex is pleased to announce that it has gained IECEx certification for its versatile process oxygen analyser range, the Servomex 2200 Series
While the maximum sample temperature for the 2200H is 110C (a 135C version is due to be launched soon), the operating point is factory-settable in 1 degree steps between 65 and 110C.
Throughout this range the analyser can be used to measure oxygen content from 0 to 100% with an accuracy of 0.04% and a repeatability of 0.03%.
Thanks to the characteristics of the fast, rugged, non-depleting paramagnetic sensor cell, zero drift is an extremely low 0.04% per week, so calibration is typically only required every three months - which further reduces the operating cost compared with alternative analysers.
Cost-of-ownership of the 2200H is minimised through an auto-calibration facility and an intuitive, multi-language text interface that requires almost no training to use.
Up to six 2200H transmitters can be linked to a single 2200 control unit, or any combination of 2200 and 2200H transmitters can be controlled simultaneously.
A single twisted-pair cable is all that is needed to link each transmitter to the control unit, with a maximum range of 1000m; electrical aspects of the installation are therefore both quick and easy.
Users can opt to use a digital or analogue output signal from the control unit, which can alternatively be installed on a Modbus network.
If required, translators are available to facilitate connection to other fieldbus protocols.
Future options for the 2200H include pressure compensation and an internal flow alarm.
Typical applications for the 2200H oxygen analyser include solvent recovery, PTA plants, vent/flare headers, solvents with high boiling points (such as xylene and toluene), sewage sludge off-gas analysis, and other processes with a sample dew point within the range 65 to 110C.
The 2200H will replace the successful Servomex 1100H model.
