October 20, 2008 - Servomex SERVOTOUGH-Oxy oxygen gas analyser provides flexibility, stability and reliability from a single, cost-effective unit.The Oxy builds on the 1900 series by providing the same measurement advantages and a series of new and enhanced operation functions that maximises flexibility of configuration and application of use. As well as fault and calibration histories, all units offer NAMUR-compliant relay functions, allowing two concentration alarm levels and maintenance required, service in progress and instrument fault messages to be communicated remotely. A comprehensive Modbus protocol allows remote communication and interrogation of the unit as standard via RS485, as well as an option for Ethernet connectivity. Autovalidation and autocalibration functions allow users complete flexibility for unmanned or remote operation, or to generate maintenance and reliability schedules using trending information. Stainless steel pipe work, automatic range change, fixed background gas compensation and measurement filtration are also now included as standard.The Oxy introduces three options designed and implemented by Servomex that not only greatly raises the standard for comparable units, but offers the potential for cost savings in installation and operational performance. A fully heated sample compartment removes the requirement for a sampling conditioning system on all samples with a dew point of up to 50 degrees centigrade. Responsible for up to 80% of failures in comparable units, sample conditioning failure is a major cause of unplanned downtime. The heated sample compartment design reduces this risk of downtime by the removal of coolers, dryers and other conditioning devices. This design improves operational cost as well as initial system and integration costs, making it especially ideal for use where ‘wet’ gases are to be measured.Servomex’s determination to deliver users the most safe, accurate and reliable levels of measurement remains at the forefront of its design philosophy – and a unique flow sensor manufactured by Servomex has been placed after the measurement outlet, guaranteeing accurate flow alarm settings for all uses including safety applications. The final major innovation of the Oxy is the creation of an integrated pressure compensation system that not only compensates for barometric pressure but also for back pressure variations from flare stacks, enabling emission compliance targets to be easily met. Both the flow sensor and pressure compensation system technologies report via the instrument’s standard communication options, providing all measurement and safety benefits without the need to install additional devices and cost-hungry cabling.The Oxy therefore offers a total oxygen solution that can be configured to the requirements of a wide range of applications. Potential applications include usage in process control, safety critical oxidation such as ethylene oxide and propylene oxide, flare stack analysis, product purity, feedstock clean-up and inerting or blanketing.The advanced capabilities of the Oxy will make it the prime replacement for older Servomex 540 and 1100 units that are at the end of their supported life. Servomex offers a comprehensive support package for users considering changeout of these units and details are available direct from Servomex’s business centres.About 1900 SeriesDeveloped using Servomex’s unique paramagnetic cell to give accurate and stable results with low maintenance and running costs, the 1900 series Zone 1 hazardous area gas analyser series established itself over 12 years as a proven performer in many arduous applications. The 1900 series is specified on numerous global oxygen licenses for oxidisation and inerting applications, having introduced a range of innovations now seen as standard, such as purge-free operation for zone 1 hazardous areas, flammable gas sampling and oxygen measurement without the need for reference gases.Servomex Group LtdAs the world expert in gas analysis, Servomex has established itself as the leading provider of reliable, accurate and stable gas measurement solutions to industries across the globe.An acknowledged innovator in gas analysis technologies for more than 50 years, Servomex is the originator of and world leader in paramagnetic sensing technology and has an exceptional reputation in the development of zirconia, photometric and thick film technologies.
