Pyrometer Models

Sensortherm pyrometers are available in many model types, since each application requires different device characteristics.

All Sensortherm pyrometers are fully digital with direct signal digitization, i.e. the measuring signal is digitized directly behind the detector without logarithmic amplifier and then linearized (Sensortherm development). No other analog circuits will be used, virtually eliminating errors that otherwise arise in analog circuits. Thus very high measurement speeds and signal outputs (response time) are reached with high accuracy, both on the digital interface and the analog output.

  • All pyrometers are ideal for industrial applications
  • With serial interface RS232 or RS485 or switchable
  • Sighting method (depending on model): through lens view finder, laser targeting light or color camera module
  • Measuring modes: normal measurement, measurement with maximum value storage
  • With SensorTools software for device settings or data recording

Metis M3/H3 Heavy Duty measuring system

The HD measuring system is designed for continuous temperature measurement in rolling mills, continuous casting plants, casting machines and similarly harsh industrial conditions.
The system in heavy stainless steel design is optimally adapted to the application conditions in the steel industry. The optics system is designed for up to 250°C, the purge air provides additional cooling and keeps the optics tube and thus the pyrometer field of vision free from contamination. The electronics of the measuring system is mounted in up to 30 meters in a protected position.
Model types: Compatible with all optical fiber pyrometers series M3 and H3

Diadem series

Diadem transfer standard pyrometers (TSP) are highly accurate and long-term stable pyrometers that are used for comparative measurements between the TS pyrometer and the pyrometer to be tested. Subsequently, the TSP temperature is transferred to the pyrometer to be tested.

  • Diadem pyrometers are traceable to the international temperature scale ITS 90, they are calibrated with PTB-calibrated reference devices and adjusted.
