Pyrometer CellaTemp PKL 28

Article description

The CellaTemp® PKL 28 has an integrated LED pilot light. Especially for small measuring objects from Ø1.2 mm, the pilot light is an indispensable aid for aligning the infrared thermometer with the hot zone and setting it to the correct focal distance. The LED pilot light is illuminated continuously and offers a high degree of operational safety due to the permanent control option. 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 250 to 1
600 °C -- switching output universally configurable -- high optical resolution due to precision lenses -- IO-Link interface -- all parameters can be set via pushbutton on the sensor or via interface from the plant system control --2 x switching outputs PNP open collector -- very simple mounting via M30 central thread -- large and bright LED display -- LED pilot light is permanently on as well as parallax-free and safe
