Furnace & Product Temperature
Short-wave and mid-wave thermal imaging borescopes look inside the furnace and measure the temperature of the slabs, billets or parts and the furnace walls continuously, so heating can be made even and fuel saved.
NIR-B-640Measuring in a range from 600 to 2000°C (1112 to 3632°F), the NIR-Borescope-640 (NIR-B-640) provides a high-resolution thermal image with real-time, continuous, high-accuracy temperature readings.
MWIR-B-640 Thermal Imaging SolutionCombustion atmospheres using dirty fuels require a thermal imaging solution with advanced spectral filtering and high resolution to deliver clear live images from within a furnace, boiler or incinerator.
Portable Temperature Checks
Portable pyrometers take quick non-contact readings at doors, discharge and along the line. Calibration sources check them in the workshop.
Cyclops LAMETEK Land Cyclops L portable, one-handed non-contact pyrometer for spot temperature readings and checking fixed pyrometers, with trigger-controlled data logging.
LandcalAMETEK Land Landcal blackbody sources for calibrating infrared thermometers from -10 °C to 1600 °C, traceable to national standards; bench, portable and transportable.
Furnace Shell Hot Spots
Fixed thermal imagers watch the outside of the furnace for hot spots that show refractory wear, and alarm before the casing is damaged.
Furnace Viewing
High-temperature cameras give operators a live view of the burners and the inside of the furnace from the control room.
Burner Ignition & Flame Monitoring
High energy igniters and gas pilots light the burners, and flame controllers prove each flame to the burner management system.
XEC 18-H Standard High Energy Power Unit18 J high energy ignition power unit for gas and light oil burners in boilers, furnaces and gas turbines, in safe-area or ATEX enclosures.
XEC 18-H Spark Check Power Unit with Ignition Feedback18 J power unit at 3 sparks per second with a feedback board that confirms the ignition process is taking place.
TP Series Gas Pilot Torches (TP15 – TP76)Gas pilot burners from 2 kW to 600 kW with high voltage or high energy ignition and optional ionisation flame detection; lengths made to order.
High Energy Ignition Spark Rods & Replaceable TipsIgnition rods in 12, 14 and 17 mm diameters with screw-on, self-cleaning spark tips (HERC17, HEM17, HEM14) rated to 760–1000 °C; safe-area or Ex d.
Compact Flame ControllersBFI compact flame controllers that combine flame detection and evaluation in one unit and tell their own burner's flame from neighbouring burners.
Flame Monitoring Fibre Optic CablesBFI glass fibre-optic cables that carry flame radiation to a flame scanner or controller, for hot (up to 600 °C) or high-vibration mounting points.
Combustion Control
In-situ TDLAS analysers measure O2 and CO in the furnace or flue in real time, so excess air can be kept low for less fuel and less scale.
Combustion Air & Draft
Multipoint thermal mass flow meters measure combustion and preheated air in large ducts, and low range differential pressure switches for burner management systems watch the furnace draft.
MT100 Flow MeterFCI MT100 multipoint insertion thermal flow meter with up to eight sensing points, for air and gas flow in stacks, flues and large ducts with short straight runs.
Low Range 107 Differential Pressure SwitchSOR 107EL low differential pressure switch for air and clean gases in hazardous areas, 0 to 1000 mm wc, for room pressure and filter monitoring.
Furnace Atmosphere Dew Point
Moisture transmitters measure the dew point of the protective atmosphere (blanket gas) in heat-treatment and annealing furnaces, where too much moisture spoils the surface finish of the parts.
