Impac’s range of pyrometers provides a robust solution for measuring temperatures in demanding industrial environments without touching the target. These infrared devices are designed for applications such as steel production, metal forging, glassmaking, and ceramic kilns where traditional contact probes would fail or interfere with the process. By detecting thermal radiation, they deliver reliable readings from a safe distance, even on glowing metal surfaces and moving workpieces. This helps manufacturers improve process control, maintain consistent temperatures, and reduce overheating or product defects. The range includes single-colour models for general high-temperature measurement as well as two-colour ratio pyrometers for applications with fluctuating emissivity, dust, smoke, or partial obstruction. Measurement capabilities span from approximately -40 °C up to 3500 °C depending on series. Specialised optics, focusable lenses, and fibre-optic variants support small spot measurement, long-distance installation, and use in harsh environments. Modular platform options also allow scalable multi-sensor configurations for complex monitoring tasks.

Impac pyrometers for metallic surfaces are built for reliable high-temperature measurement in industrial processes where contact sensors are impractical or would fail. These infrared pyrometers measure thermal radiation without touching the target, making them ideal for molten metal, forged parts, hot billets, ceramics, graphite, and other demanding applications.
The range includes compact fixed units, portable instruments, two-colour pyrometers, and fibre-optic pyrometers for installations exposed to heat, vibration, dust, smoke, or electromagnetic interference. With broad temperature coverage, flexible optics, and industrial output options, they provide dependable non-contact monitoring for process control, quality assurance, and equipment protection.

voor Pyrometers uit de Impac-serie voor metalen oppervlakken
A non-contact temperature sensor can measure extremely hot objects without physically touching them. In metallurgical and high-temperature processes, thermocouples may be damaged by molten metal, difficult to mount on moving material, or unsuitable because they risk contamination. An infrared pyrometer detects emitted radiation from the surface, allowing safe and continuous monitoring with low maintenance.
A two-colour pyrometer measures temperature at two nearby infrared wavelengths and compares the signal ratio. This helps reduce errors caused by changing emissivity, dust, smoke, flames, or partial obstruction. It is especially useful for shiny, oxidising, or moving metal targets where single-wavelength measurement may be less stable.
This depends on the optics and model selected. Many Impac units offer precision lenses and focusable optics for very small measurement spots, with some applications reaching around 0.5 mm at close range. High optical resolution also supports longer-distance measurement, while fibre-optic pyrometers allow the sensing head to be mounted close to the target and the electronics to remain further away.
Response times are typically in the millisecond range, making these sensors much faster than many contact probes. Certain models are designed for highly dynamic processes and can respond in sub-millisecond or even microsecond-level timeframes. This makes them suitable for moving products, short thermal events, and rapid process transitions.
Many models include built-in sighting aids such as a laser aiming point, optical sight, or LED spot indication. These help users align the sensor with the exact measurement area, even at a distance or through a viewing port. Focusable optics on selected models also allow the measurement spot to be adjusted for the target distance.
Most models are designed for industrial integration and provide analogue outputs such as 0–20 mA or 4–20 mA. Many also offer digital communication via RS232, RS485, or USB for configuration and data access. Depending on the series, this allows connection to PLCs, controllers, PCs, and broader process monitoring systems.
Yes. These pyrometers are built for harsh industrial settings and are available in rugged housings suited to high ambient temperatures, vibration, and difficult installation points. Fibre-optic pyrometers are especially useful where the optics must be placed near the heat source while the electronics remain protected. Optional accessories such as cooling, air purge, and protective mounting hardware further improve long-term reliability.
The sensors are factory calibrated and use stable detector designs to support long-term accuracy. Periodic recalibration using a suitable blackbody reference is recommended to verify performance over time. Many models also support emissivity adjustment, offsets, and self-diagnostic functions that help maintain reliable high-temperature measurement in daily operation.
Yes. Configuration and analysis software such as InfraWin can be used with compatible models via USB or serial connection. This software typically allows users to adjust parameters, view live readings, log temperature data, set alarms, and analyse trends. It is useful for both commissioning and ongoing process optimisation.
Selection depends on several factors: required temperature range, target material and emissivity behaviour, target size, installation distance, process speed, and environmental conditions. For example, a highly reflective or changing metal surface may benefit from a two-colour pyrometer, while a confined hot zone may require a fibre-optic pyrometer. Reviewing the series specifications and matching them to the application is the best way to identify the most suitable model.
