Pyrometer CellaTemp PK 29

Article description

The CellaTemp® PK 29 is equipped with a special blocking filter. As a result, the measurement is not affected by daylight. This pyrometer also responds substantially less sensitive on reflective external radiation from hot objects around than conventional devices working at short wavelengths. This means that the CellaTemp® PK 29 can be used for a wide variety of applications in the metalworking industry and in particular for measuring the temperature of aluminium and bare metals at low temperatures. Due to the blocking filter, it can also be used for measurements in processes in which diode, Nd:YAG or CO2 lasers are used for heating. The energetically high laser radiation does not influence the measurement. The new generation of the CellaTemp® PK pyrometer series is equipped with a smart function, the vitality indicator.
This is a self-monitoring, analysis and reporting technology (SMART), i.e. a function for self-monitoring, analysis and status reporting. The vitality monitor continuously records all relevant operating data. As part of preventive maintenance, this enables the pyrometer to autonomously signal the optimum time for a service check and calibration, depending on the operating conditions.
