MEASUREMENT & TESTING New thermal cameras for fire detection and condition monitoring
The FLIR A500f and A700f Advanced Smart Sensor ruggedised thermal cameras feature high- temperature detection for extreme environments paired with on-camera analytics and alarm capabilities – ideal for industrial early fire detection or outdoor condition monitoring applications. Along with enhanced spot, area, line, polygon, and polyline analytic functions that improve the definition of areas of interest and object curvatures, the A500f/A700f can help commercial and industrial organisations protect assets, improve safety, maximise uptime, and minimise maintenance costs.
For early fire detection, the A500f and A700f thermal cameras can quickly identify increased temperatures related to potentially dangerous conditions. If smoke is present, the cameras can help provide increased awareness for decision makers to properly assess and address incidents. Both cameras feature Flexible Scene Enhancement (FSX) technology, found on Teledyne FLIR K-Series handheld firefighting devices. The result is an ultra-sharp, finer-textured image that shows subtler edge details supplied by the embedded visible camera onto the thermal image, enabling operators to recognize objects and people more easily.
The A500f/A700f are also effective tools for pile-burn monitoring, providing automated early warnings for potential issues in waste management facilities or coal collection areas that operate around the clock.
Manufacturing facilities, chemical processing locations, or power substations that use common communications and control language can also benefit from the A500f and A700f beyond fire detection. These cameras empower those organizations to reduce maintenance costs by identifying heat anomalies from mechanical problems early, thereby extending the life of plant components while maximizing uptime.
Featuring a protective IP67-rated housing designed to withstand temperatures between -30° to 50°C (-22° to 112° F), the A500f/A700f cameras are designed for harsh environments and discreet enough to deter from theft. In addition, the cameras use a single power-over-Ethernet (PoE) cable for both power and communication, helping to further minimize points of potential failure.
The A500f/A700f offers superior thermal imaging capability with a resolution of 464 x 348 (161,472) for the A500f and 640 x 480 (307,200) thermal pixel resolution for the A700f. Users can expect a ±2° C (±‐3.6° F) temperature measurement accuracy.
The A500f has a temperature detection range between -20° to 1500°C (-4° to 2732° F), while the A700f offers a temperature range of between 20° to 2000°C (68° to 3632°F) for detecting chemical fires and other extreme industrial fire conditions.
Along with thermal lens options ranging from 14° to 42° and an embedded HD visible camera, these devices fulfill the needs of most outdoor condition monitoring and fire detection applications.
Installing the FLIR A500f/A700f cameras is seamless. Both cameras are ONVIF compliant and integrate easily into standard security VMS and NVR solutions including control of pan/tilts.
For VMS integrations, thermal and visible streams can be viewed independently or simultaneously. The cameras are easy to add, set up, and operate in HMI (Human Machine Interface) SCADA (supervisory control and data acquisition) systems, offering automation system solution providers a running start. Both the A500f and A700f fully support IIoT protocols such as MQTT (Message Queuing Telemetry Transport) and RESTful API with a system unique token key for extra security.

Advanced and rugged enclosure makes PEMS ideal for NRMM and HDV harsh environment real world emissions monitoring
Horiba has launched an advanced rugged enclosure for its versatile OBS-ONE portable emissions measurement system (PEMS), enabling it to be used for the in-service monitoring of real world emissions (RWE) of combustion engine powered non-road mobile machinery (NRMM) in real-life operational and often harsh environments.
Called the OBS-ONE-RE, the enclosure is a feature-rich system in its own right and enables the OBS-ONE – as trusted the world over by leading OEMs of light- and heavy-duty vehicles for establishing real-driving emissions (RDE) and in-service conformity – to be used for monitoring the exhaust gases of machinery such as diggers, quarry vehicles, snowmobiles, inland water vessels and portable power generating sets.
Les Hill, Manager of HORIBA’s Global Product Planning Group and a member of a number of RDE working groups, comments: “In 2016, the European Commission published the EU Stage V legislation for Non-Road Mobile Machinery. Subsequently, in 2019, the in-service monitoring of NRMMs became mandatory, to monitor for discrepancies between engine-under-test emissions established in the laboratory and real-world emissions when the engine is installed in equipment and in use.”
Launched in 2014, HORIBA’s OBS-ONE measures concentration levels of gaseous emissions – specifically carbon monoxide (CO), carbon dioxide (CO2
), total hydrocarbons (THC), nitrogen oxides (NOx
The OBS-ONE-RE features high endurance and reliable springs that protect the OBS-ONE from shock and vibration in all three axes. In addition, the OBS-ONE-RE is weather-proof, has dust filters and has a cooling system that maintains a consistent internal temperature; enabling the OBS-ONE-RE to operate over the range -7 to +40o
C. Built-in Wi-Fi allows the OBS-ONE-RE to be operated and monitored remotely, enabling the NRMM driver to concentrate on the vehicle or machinery operation.
This rich feature set makes the rugged enclosure the perfect solution for protecting the OBS-ONE from the harsh environments in which many NRMMs, and some HDVs operate and which must now be monitored under industry regulations.

Lewis George, Product Design Engineer of HORIBA UK’s R&D department, comments: “The OBS-ONE-RE is the result of extensive research, development and verification, including testing on the shaker rigs of certified test houses and on various NRMM vehicles, to ensure the product’s durability and robustness. Most importantly, the OBS-ONE maintains a stable response within tolerances appropriate for certification.”
George goes on to explain that HORIBA is already the go-to company for LDV RDE PEMS and for HDV in service monitoring PEMS, adding: “Now we’ve risen to the challenge of taking our trusted and reliable PEMS out into the harshest environments, which will be useful for product development purposes as well meeting the industry’s requirements for in-service monitoring post product launch. Also, our solution offers easy onsite customisation, ensuring monitoring can be performed reliably while ensuring the safety of those operating the OBS-ONE.”
Those developing NRMMs or HDVs likely to be used in harsh environments are encouraged to contact Horiba for further information on the latest RWE regulations, likely changes to regulations in the future and how Horiba’s proven and trusted OBS-ONE and the Rugged Enclosure can help them achieve compliance and de-risk their programmes.
