The Most Reliable Choice for Life Safety Oxygen Detection

Servomex’s OxyDetect is the most reliable oxygen monitor available for life safety applications, with non-depleting sensor technology that provides ultimate protection in both safe and hazardous areas of hydrocarbon processing plants.

Plants can be further assured of its reliability after the hardware attained Safety Integrity Level (SIL) 2 certification, a measurement of performance required for a safety instrumented function.

Matt Halsey, Servomex Product Manager - Process Oxygen, Zirconia & Oxygen Deficiency said: “SIL is an internationally recognised assessment of reliability. The SIL rating corresponds

to the probability that a safety function will work when required to do so. SIL 2 tells us that the hardware will be in a functional state if it is required to do its job.

“SIL hardware compliance makes the OxyDetect easier to integrate into a customer’s safety system, and allows us to target key applications in the marketplace. “It offers customers peace of mind that the OxyDetect is safe.”

Manufactured by Servomex, the world leaders in gas analysis, the OxyDetect uses the market-leading performance of the company’s Hummingbird Paracube Paramagnetic sensor, which provides a long- lasting, fast-reporting oxygen measurement.

Unlike electrochemical cells, which have long been the standard in many industries for O2 ambient

air monitoring, this Paramagnetic technology is non-depleting, so it will never run out or require replacement.

Electrochemical cells require regular calibration every few months to reduce drift, whereas the OxyDetect requires infrequent calibration, making it the best choice for critical area monitoring.

These performance benefits also significantly reduce the cost of lifetime ownership of the OxyDetect. In addition, it is easy to use, with a simple front-panel digital interface allowing easy access to advanced microprocessor-based diagnostics.

It is available as a hazardous or safe area version, with updated communication relay and MODBUS options. For more information, visit

New Device Makes Older-model Gas Detectors Connected, Simplifying Maintenance and Reducing Downtime New Optima Excel Local

Display upgrades capabilities of Honeywell’s Optima gas detectors used throughout oil and gas, petrochemical and energy industry. Allows mission-critical maintenance to be performed wirelessly in risky environments faster, cheaper and with reduced downtime.

Honeywell announced today a new Bluetooth-enabled device that brings connectivity to fixed gas detectors used in the oil and gas, petrochemical and energy industries, enabling workers to use a smart phone to perform mission-critical maintenance and avoid costly downtime in potentially explosive environments.

Honeywell’s new OELD (Optima Excel Local Display) attaches to Searchpoint Optima Plus, a staple safety device for more than 20 years on offshore drilling platforms and in operation at more than 250,000 points of detection throughout the oil and gas industry; in addition, the OELD will soon be available as an accessory for the company’s flagship open-path infrared detectdor, Searchline Excel. With the attached display, workers can view gas information from the detector on the display screen or wirelessly from up to 10 meters on an intrinsically safe smart phone. Workers can wirelessly perform a host of diagnostic work on the detector, including calibration, configuring alarm set points, specifying target gases and checking gas concentration levels and sensor performance.

“Honeywell has brought familiar smart phone technology to a mission-critical maintenance task for the energy industry, which can now be accomplished more easily, quickly, and cost effectively than ever,” said Carl Ritzberger, marketing director for fixed gas detection at Honeywell Industrial Safety, a global leader in gas detection. “Best of all, because the maintenance work is non-intrusive, operators do not have to apply for a ‘hot work’ permit that temporarily shuts down or declassifies a process area, resulting in expensive downtime. With the wireless connection, there’s no need for the worker to go back and forth to the control room, to open up the detector to do the work, to climb ladders or crawl into ducts to access hard-to-reach installation points.”


The new independent Guide to Gas Detection has been published by CoGDEM (The Council of Gas Detection and Environmental Monitoring) to provide industry professionals with a complete reference document on the accurate, reliable measurement of gas concentrations in both process control and occupational safety applications.

This book provides the latest information on UK, EU and global regulations.

Chapters in this Guide include:

•Selecting a Detection System •The Chemistry and Dangers of Gases •Training

•Calibration •Performance Evaluation •Reference Documents

This book provides practical guidance and is ideal for training and reference for Professionals interested in gases.

The Optima Excel Local Display features an LCD screen for gas information that clearly displays real-time information on the detector’s status, supplementing the Optima or Excel’s standard communication bridge to the control room. In addition, the display has bright indicator lights in a familiar ‘traffic-light’ pattern that are visible from a distance: green for normal; yellow for a fault condition; and red for an alarm.

Available in aluminum or stainless steel housing, the local display is approved and rated for a wide range of hazardous environments such as oil and gas, petrochemicals, power generation, heavy manufacturing and lithographic printing.

Honeywell Industrial Safety, part of Honeywell’s Safety and Productivity Solutions group, is a global leader

in gas detection, with the industry’s broadest portfolio of portable, fixed, single and multi-gas detectors. It is also a global leader in personal protective equipment (PPE), head-to-toe turnout gear and self-contained breathing apparatus for first responders. Honeywell’s software offerings connect workers and employers with data-driven, real-time intelligence to increase jobsite safety, productivity, efficiency and bottom-line performance.

This book is available to purchase in hard copy at or call us on +44 (0)1727 858 840 to place an order

The AFRISO WGA 02 alarm unit for oil separators, consisting of the control unit WGA 02 and the conductivity probe WGA-SD 03, monitors the thickness of the oil layer in oil separators and triggers visual and audible alarms if a defined level is reached in the oil separator. The unit excels with a high reliability since the connection cable to the probe and the probe itself are continuously monitored for short circuits and line interruptions. The maximum distance between WGA 02 and the probe is 300 m. The electronic system is contained in a robust wall mounting housing with indicators and buttons on the front (1 LED for operation, 2 LEDs for alarm and error, 1 Acknowledge and 1 Test button). Two voltage-free relay outputs are provided for transmission of signals. The system is supplied with AC 230 V and suitable for operating temperatures from 0 °C to +60 °C. Shipped as a complete system (control unit, probe, junction box and mounting material), the alarm unit is fast and easy to commission. The alarm unit is approved for use in hazardous areas. The probe itself may be installed in zones 0, 1 or 2. However, the control unit may only be installed outside of hazardous locations.
