Product catalog summary

Introduction
The document discusses the CellaInduction measuring system, designed for precise temperature measurement in hot-forging processes using induction heating. Induction heating is favored for its quick heat-up, uniform heat distribution, and precise temperature control, essential for heating steel billets to temperatures between 1000°C and 1250°C.

Temperature Measurement
Temperature control in induction heating systems is achieved using pyrometers, which are infrared thermometers that measure temperature without contact. Pyrometers can be single-colour or two-colour, with the latter offering advantages such as reduced sensitivity to contaminants and emissivity fluctuations.

Advantages of Two-Colour Technology

Less sensitivity to contaminants like steam, dust, and smoke.
High operational safety with signal intensity monitoring.
Compensation for emissivity fluctuations.
Less sensitivity to focal distance and target adjustment errors.

Optical System and LED Spot Light
The CellaTemp® PKL features a high-quality glass lens and an integrated LED spot light for precise alignment and measurement. The LED spot light is safe for the human eye and provides a bright, sharp light for accurate targeting.

Solution
The CellaTemp® PKL infrared thermometer is designed for induction heating applications, offering easy installation, quick response time, and features like DTD for discontinuous processes. It includes a bright LED display and switching contacts for rejecting billets outside the permissible temperature range.

Models and Specifications
The document lists various models of the CellaTemp® PKL, detailing their temperature ranges, focal distances, and measurement techniques. Models like the PKL 29, PKL 38, and PKL 68 are tailored for different temperature ranges and materials.

Accessories
Accessories include shielded cables and mounting brackets, enhancing the system's adaptability to different industrial environments.

Application note Measuring system CellaInduction Induction heating Advantages of the two-colour technology Advanced induction heating systems are widely employed in today’s forging industry for hot-forging applications. Prior to forging, steel is heated to a temperature between 1000 °C and 1250 °C. The required process temperature depends on the carbon content and the specific alloying elements of the steel. Hot forging requires uniform heat distribution across the width and the length of the workpiece. The billet is heated to a temperature above its recrystallization temperature. Induction heating...

Solution The infrared thermometer CellaTemp® PKL was especially developed to optimally fulfil the special requirements for the temperature measurement in induction heating application. The compact design with a M30 central thread offers easy installation options even under limited space. With the response time from 2 ms the instruments provide the necessary short time for the rejection of the billets and for a quick temperature control. For checking the right focal distance and the alignment, the infrared thermometer is equipped with a continuously illuminated LED spot light. It shows both the...
