New Oxygen Analyser

Offering an exceptional range of industry standard options and three unique, ground-breaking functions, the forthcoming SERVOTOUGH-Oxy
oxygen gas analyser from Servomex (UK) will set new standards of flexibility, stability and reliability from a single, cost-effective unit.
The Oxy builds on the success of 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 unique 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.
An innovative, 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.
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.
