14 Safety Video Demonstrates Safer Furnace Inspection by IR Camera


FLIR Systems has produced a video showing how the FLIR GF309 IR camera aids inspection of high temperature furnaces as used in the chemical, petrochemical and utility industries.


The FLIR GF309 is an IR camera for the high-temperature measurement of industrial furnaces, chemical heaters, and coal-fired boilers, without the need to shut down the operation. The portable camera also greatly improves operator safety, by measuring through flames at a safe distance, for all types of furnaces. A good knowledge of the furnace condition can avert failures and unscheduled shutdowns.


Suitable for monitoring all types of gas-fired furnaces, chemical heaters and coal-fired boilers, the FLIR GF309 measures temperatures from -40°C to +1500°C with high accuracy across the range. To protect the camera and the operator it has a contoured, nickel-coated heat-shield to reflect the heat. It is ideal for a range of extreme temperature applications including inspecting tubes for reduced heat transfer due to scale build-up and localised tube failure due to overheating.


The FLIR GF309 provides temperature readings across the entire surface of the heater, boiler and furnace without the need to interrupt the process. It allows inspection to be accomplished faster and safer, averting unscheduled shutdowns and costly catastrophic failures. This ability is greatly complemented by the cameras wide operating temperature range and detachable heat-shield. As a result the FLIR GF309 can be used for all manner of electrical and mechanical inspection tasks from predicting the life of a bearing to spotting poor electrical connections.


The GF309 furnace inspection camera has in-built GPS that automatically documents satellite co-ordinates, enabling swift identification of the problem site and improving repair logistics. It also has a high sensitivity of <25mK so that small faults can be seen at a good range. Additional features include an in-built, high quality visual camera and a lamp for use in dark environments.


Lightweight – just 2.4kg – and robust, the FLIR GF309 has a high performance and tiltable viewfinder. This can be adapted to the individual user and particularly effective outdoors as it shows a very sharp image without the influence of ambient light or reflection. A turntable control grip allows the camera to be used in the most comfortable position; programmable direct access buttons and joystick control are integrated into this handle.

Detcon (USA), an IST company, is pleased to announce the Site Sentinel is fully certified to North American hazardous-area approval requirements. All models of the CXT (wireless) and CX (wired) combustible and toxic gas detectors are certified cCSAus Class I, Division 1, and both the CXT Controller and CX Sensor Station are certified cMETus Class I, Division2. Designed for fixed or transportable use in a wide range of applications, the flexible and field-expandable Site Sentinel can include up to 32 gas detectors and can be configured for any combination of wired and wireless devices.


Additional Site Sentinel components include wireless alarm stations and the new state-of-the-art Sentinel SiteWatch gateway to alert personnel of potential danger. The Sentinel SiteWatch provies advanced networking capability with email and text messaging on all fault and alarm events through Ethernet or Cellular communications. Web-page remote monitoring of the safety system is also available through Ethernet communications.


All wireless components of the Site Sentinel operate on a 2.4GHz frequency, have a two mile line-of-site communication capability, and use an innovative “Mesh Network” topology that allows each device to operate as a repeater within the network, ensuring redundant and reliable communication. The wireless system can also be armed with an extra measure of network protection when configured with Detcon’s patent-pending “Fault Tolerant Safety Network.” This technology allows any device in the network to operate as a master device if needed, thereby eliminating any single-point of failure.


Critical fault diagnostics are available locally or through a link to the other members of the network. Power options for system components include disposable batteries, rechargeable battery packs with solar power options, and line power.


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).
