Infrared thermometer CellaCombustion PK 73

probewith LED display°C

Product description:
The CellaCombustion PK 73 is an industrial infrared pyrometer designed to measure hot combustion gases at a wavelength where combustion gas components present high optical density. It is intended for large combustion plants such as waste incineration facilities, coal-fired power plants and other industrial furnaces. The PK 73 features the CellaTemp® PK series vitality indicator (SMART) for self-monitoring, analysis and reporting, enabling predictive maintenance by signalling optimal times for service and calibration based on operating data.

Special features:

• Measuring range 500 to 2,500 °C
• Compact design with narrow field of view
• Universally configurable switching outputs (2 x PNP)
• High optical resolution with precision lenses
• IO-Link interface (V1.1.3)
• Parameter setting via sensor pushbuttons or plant control interface
• Easy M30 central-thread mounting
• Large, bright 4-digit LED display
