62 Safety New Five Year Long-Life Oxygen Sensor
Tyco Gas & Flame Detection is pleased to announce the release of a new long life Oxygen sensor for the OLCT 60.
The OLCT 60 is a 4-20 mA analogue gas transmitter designed for industrial applications in hazardous locations.
The new design is lead free and has an operational life of five years. The range is from 0 to 30% vol. O2 and the sensor operates from -40°C to 50°C continuously allowing new opportunities in low temperature
applications.
This new Oxygen sensor completes the range of our current 2 year life O2 warranty and is compatible with any existing OLCT 60 O2

Life Safety Oxygen Monitor Attains Safety Integrity Level 2 Certification
Customers using Servomex’s OxyDetect life safety oxygen monitor can now be further assured of its reliability after the hardware attained Safety Integrity Level 2 certification.
Available as a hazardous or safe area version with updated communication relay and MODBUS options, the recently-launched OxyDetect offers a highly accurate oxygen measurement without the sensor deterioration that degrades the performance of traditional electrochemical sensors used in competitor detectors.
The OxyDetect utilizes the market-leading performance of Servomex’s Hummingbird Paracube Paramagnetic sensor, whose industry-leading levels of linearity, accuracy and reliability have ensured its use as a trusted oxygen sensor for the OEM medical market.
Safety Integrity Level (SIL) is a measurement of performance required for a safety instrumented function. It is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction.
Matt Halsey, 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.”
In the European functional safety standards based on the IEC 61508 standard, four SIL levels are defined. SIL is determined based on a number of quantitative factors in combination with qualitative factors such as development process and safety life cycle management.

benzene concentrations can be measured rapidly and accurately in the presence of the hundreds of aromatic and aliphatic compounds encountered in the industry.
Traditionally it has not been possible to collect accurate measurements due to a lack of available technology. However, Ion Science offers a range of high performance personal, handheld and fixed benzene specific detectors for use in hazardous applications across the world.
For data critical zones, Titan is the world’s only fixed, continuous benzene specific monitor for detection of ambient benzene in petrochemical and refinery applications where traditional methods suffer cross interference. Providing the ultimate real-time protection of workforce, environment and plant, Titan is capable of detecting benzene levels down to 0.1 ppm and up to 20ppm.
When a sample is taken, the benzene component is chemically filtered using robust separation technology which eliminates false negatives and positives.
With a robust and reliable design, the Ion Science Tiger handheld PID provides a dynamic detection of one ppb to 20,000 ppm, offering the widest measurement range on the market. It is easy to set up and provides advanced volatile organic compound (VOC) detection with advanced software features. It has a fast response time of just two seconds and can be connected directly to a PC via the USB offering rapid data download capabilities.
The versatile Tiger Select model has two mode operation for the accurate detection of benzene and total aromatic compounds (TACs). Utilising the high output Ion Science 10.0eV PID, a reading for TACs is seen immediately on start-up.
Should TACs be detected, a benzene pre-filter tube can be easily attached to allow rapid detection and selective measurement of benzene.
Throughout the measurement process, Tiger Select continues to display real time data, keeping the worker safe. Benzene concentrations are displayed down to ppb levels.
As the world’s smallest, lightest and most sensitive gas detector, Ion Science’s CubTAC personal PID features audible, vibrating and flashing LED alarms designed to give workers an early warning of exposure to hazardous gases, including benzene, before they reach harmful levels. CubTAC also uses the 10.0ev PID to give a reliable aromatic hydrocarbon concentration.
The Titan, CubTAC and Tiger Select all incorporate Ion Science’s next generation MiniPID 2 sensor which offers increased temperature stability, greater sensor-to-sensor consistency and more repeatable performance at low temperatures.

Ion Science MiniPID 2 sensors include patented Fence Electrode Technology for industry leading humidity resistant performance whilst ensuring fast and accurate detection of VOC gases. With its anti-contamination design, drift is minimised by protecting the sensor from moisture, dust and aerosols. The MiniPID 2 also offers an innovative self-diagnostic feature that indicates whether the lamp is failing to illuminate or the electrode stack is contaminated.
