Fixed Continuous VOC Monitor for Maximum Plant & Worker Safety Launched


Ion Science (UK) has announced the launch of its Falco series of fixed continuous VOC (volatile organic compound) monitors for the on-going protection of workers operating in potentially hazardous industrial environments, such as refineries, petrochemical plants and laboratories. Incorporating first of a kind ‘typhoon’ technology for added reliability, Falco is specially designed to work in condensing atmospheres and extreme weather conditions.


Reinforcing Ion Science’s position at the forefront of gas detection instrumentation for occupational health and the environment, Falco boasts fast response times and several innovative design features. The instrument’s ‘typhoon’ technology prevents condensation forming on the sensor and removes the risk of the system short circuiting - making it ideal for use in harsh weather conditions.


The new PID (photoionisation detector) is simple to operate while an externally located, IS (intrinsically safe) sensor facilitates quick and easy servicing without the need for a hot work permit.


Ion Science Managing Director, Duncan Johns, comments: “Falco will set a new benchmark in fixed VOC monitoring for hazardous areas and help ensure plant-wide safety and on-going protection of employees likely to be exposed to VOCs. The ‘typhoon’ technology was developed as a result of feedback from customers who said that similar monitors had failed in extreme weather conditions. Our R&D team discovered that where ambient air quickly changes from cold to hot, it generates condensation in the sensor which adversely affects performance. The new ‘typhoon’ technology enables the system to cope with these sudden fluctuations.”


Falco is operated via an intuitive user interface with OLED display and five magnetically activated switches – up, down, left, right and enter – which are back lit to help confirm the correct button is being pressed.


For added convenience and ease of use, brightly coloured red, amber and pulsing (optional) green status indicators are clearly visible in sunlight allowing checks to be conducted from a distance.


Incorporating Ion Science’s market-leading PID technology with advanced patented fence electrode system, Falco’s three-electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field, as well as considerably reduced drift issues and extended run time.


Falco utilises a diffusive sample technique resulting in less contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements. Pumped models are available for applications where a sample needs to be drawn to the unit.


There are eight models in the Falco series offering detection ranges as low as 0 - 10ppm with ppb sensitivity or as high as 0 - 10,000ppm. Customers can upgrade to a unit with a higher detection capacity by purchasing a different electrode and simply recalibrating.


Duncan continues: “Falco underlines our commitment to designing gas detection technology that provides both flexibility and cost benefits. A customer normally purchases a fixed VOC monitor based on its detection range. Previously, choosing the wrong model by mistake meant they would have to purchase a completely new system. With Falco, they can easily and cheaply upgrade by buying the relevant electrode.”


The Falco’s flame and explosion proof enclosure is certified to EX d IIC T4 II and the external sensor to EX ib IIC T4 Gb II. A 4 – 20 mA analogue output enables Falco to be easily integrated into a DCS control system to give warning or control of high VOC levels in the working environment. Two relay outputs means it can be connected remotely plus RS485 output with Mobus protocol included as standard allows the instrument to be connected to a network.

New Software Reduces Alarm Rationalisation Time and Cost


One requirement of Pipeline Operational Excellence in the control room is the implementation of an Alarm Management Plan, including rationalisation of all safety alarms to reduce alarm flood as required by the PHMSA CRM rule.


The cost of implementing an Alarm Management Plan can reach $300,000 or more. However the biggest component in this cost is not the software, it is the time and cost that company personnel spend rationalising each safety alarm. The result of rationalising each alarm is to define its alarm priority – critical, high, medium, or low and to create an alarm response sheet to guide the controller’s actions. Typical alarm rationalisation exercises involve 5 or more people sitting around the table discussing what caused the alarm, how to confirm the alarm, what happens if the alarm is ignored, and what action to take to prevent “bad things” from happening. If each alarm takes 15 minutes of conversation, and you have 2,000 safety alarms to rationalise that results in 5+ of your key people spending up to 12 weeks, or 2,500 man/hours on this exercise.


Is there a better way? We think so and you prove it to yourself – request information on the EnerSys (USA) POEMS Alarm Management software (ALMgr) and get the FREE Alarm Rationalization Cost Estimator.

Advanced Multifunction Gas Detection System


The GALILEO SMS (SIL Multisystem), from Sensitron (Italy), is an advanced multifunction gas detection control panel designed to comply with the SIL (Safety Integrity Level) requirements, according to the European Standard EN 50402 and IEC 61508 on Functional Safety. The functional safety is aimed at supervising and managing the behaviour of an overall system in case of failures.


To assure a full redundancy, the control unit’s main board is designed around 2 powerful microprocessors that communicate to each other the monitored data, ensuring


the complete availability of all main board functions even in the case of a failure in one microprocessor. A broad range of self- testing facilities are implemented to detect and localise possible faults.


The redundancy offered by every module being part of the system, added to the possibility to communicate with remote input/ output modules via a redundant closed BUS, makes this system comply with the Functional Safety requirements up to SIL3.


The GALILEO SMS consists of a control unit, used for monitoring and controlling, connected to an optional number of Analogue Input Modules (AIM), LOOP modules and RELAY modules.


The system will be connected in two digital RS485 (EIA-485) type closed loops capable of accommodating a maximum of 256 gas detectors connected as addressable gas detectors type SMART3G or SMART3 “S” connected via 32 input loop modules or analogue 4-20mA detectors connected through 8-input AIM (Analogue Inputs Modules), and a maximum of 520 relay outputs connected as 512 programmable relays on the Relay Outputs modules (8-16 relays module, basic and extended respectively).

Advanced NDIR Sensor for SF6 or Refrigerants Detection


The IR series of infrared gas detection sensors, from N.E.T. (Italy), use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of SF6 or refrigerants. This technique is based on the fact that the gas has a unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable infrared source and by analysing the quantity of energy absorbed from the gas inside the optical path. The IREF-P sensor is equipped with electronics and firmware in order to provide an output that is linearised and temperature compensated. The output is analogue voltage type [0.4 V—2 V] dc (other voltages are available on request). IREF P is now SIL2 approved.


The main features are: analogue voltage standard output, incorporated signal, linearisation and temperature compensation suited for instrument manufacturers without any specialist knowledge in IR technology, standard sensor size 32 mm,


fast response, solid, rugged construction, wide operating temperature and humidity range (-20°C +60°C) and new optics “Variable Geometry”.
