Infrared thermometer CellaTemp PKF 67

two-colorfiber opticwith LED display

Product description
The CellaTemp® PKF 67 features separate electronics and measuring head. Infrared radiation is transmitted to the electronics via a fibre optic cable, allowing the measuring head to operate without cooling at ambient temperatures up to 250 °C. This design is suitable for confined mounting spaces and environments with high electromagnetic interference. Fibre optic cable lengths up to 50 m are possible. The latest generation of the CellaTemp® PK series includes a SMART "vitality indicator" that continuously monitors operating data and signals the optimal time for service or recalibration based on operating conditions.

Special features

• Measuring range 600 to 1,400 °C
• Fibre optic cable version — up to 50 m length possible
• Universally configurable switching output
• High optical resolution via precision lenses
• IO-Link interface
• All parameters adjustable via sensor pushbuttons or plant control interface
• 2 × switching outputs PNP open collector
• Easy mounting via M30 central thread
• Large, high-visibility LED display
