Pyrometer with LED display CellaTemp® PKF 36

°CIO-Linkstationary

Product description:
The CellaTemp® PKF 36 has separate electronics and measuring head. The infrared radiation is transmitted to the electronics via a fibre optic cable. The measuring head can be used without cooling in ambient temperatures up to 250 °C. This version can also be used in cramped mounting conditions or high electromagnetic fields. The length of the fibre optic cable can be up to 50 m. 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.

Special features:

• Measuring range 550 to 2,500 °C
• Fibre optic cable version up to 50 m length possible
• Switching output universally configurable
