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
This will be a major benefit for users that are implementing Ethernet communications networks plant-wide and, via TCP/IP, worldwide While this is the first product from the company to offer Ethernet communications, many more can be expected in the future

Servomex 2200H oxygen analyser displaces 1100H FM
Servomex is announcing that its successful 1100H FM high-temperature oxygen analyser will be obsolete with immediate effect, and the 2200H instrument will be offered instead
As with the existing models in the Servomex 2200 range, the new Ethernet-compatible version is certified as being intrinsically safe to Ex ia; with no need for a safety purge, the analyser costs less to install and operate, whether it is used in a new installation or as a replacement.
It is fully approved for use in ATEX category 2 applications, is certified as flameproof to EExd, and has IECEx certification, FM (Factory Mutual) and CSA (Canadian Standards Association) approvals.
Whereas previous Servomex 2200 oxygen analysers have been available with Modbus and RS232/485 communications - which enables measurement data and status information to be read by a Distributed Control System (DCS) or similar equipment - the new model with Ethernet communications opens up far more possibilities.

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
With Ethernet fast becoming an industry standard for both factory/plant-level communications and cell/control-level communications, there is a market demand for field-level devices that use the same protocol.
The Servomex 2200 Ethernet meets this need, enabling measurement and status data to be shared with other field devices, human-machine interfaces, local control systems, and plant-level management information systems.
Furthermore, Ethernet communications enable devices to be interrogated from anywhere in the world via a standard web browser using TCP/IP.
Better information availability equates to greater operational efficiency, improved decision-making and enhanced customer service.
To enable the Ethernet communications to be incorporated in the 2200 analyser, Servomex has had to make only minimal changes to the hardware and software.
This means that it has been a relatively straightforward process to gain the same certifications as are already in place for the existing models of 2200 oxygen analyser.
It also minimises technical risk, so customers can be confident that the new model will have the same exceptionally high performance and reliability as the existing variants.
Features that help to minimise the cost of ownership from the Servomex 2200 oxygen analyser include a rugged, non-depleting paramagnetic sensor cell that has extremely low zero drift, and an auto-calibration facility.
In addition, the unit has an intuitive, multi-language text interface, that requires almost no training to use.
Up to six Servomex 2200 transmitters can be linked to a single Servomex 2200 Ethernet control unit via twisted-pair cables, with a maximum range of 1000m, and the control unit communicates via a single RJ45 Ethernet connection; electrical aspects of the installation are therefore both quick and easy.
More information about the Servomex 2200 Ethernet process oxygen analyser, as well as other Servomex gas analysers, all of which are available and fully supported worldwide, can be found on the website.
