Important Factors in Choosing an Oven Profiling System

Choosing an oven profiling system? There are some important factors to consider before you decide. The SCORPION® 2 profiling systems from Reading Thermal in Sinking Spring, Pennsylvania, can help you make adjustments to achieve superior products.

The innovative SCORPION® 2 Data Logger with Temperature Sensor Array from Reading Thermal measures, captures, and stores oven temperature profiles so that you can bake your products to perfection.

What Are Your Requirements?

Before you decide on a data logging measurement system, you should consider both your current and future requirements. You will have to determine how many inputs you will need, how much data you want to capture and store, what software features you will need.

The Reading Thermal SCORPION® 2 Data Logger provides a complete measurement system to capture the four key baking parameters: temperature, air velocity, humidity, and heat flux, enabling you to measure and analyze baking, drying, and cooling processes.


The SCORPION® 2 Temperature Sensor Array measures the temperature at product level and delivers an accurate representation of what your product experiences over time. Different types of pluggable sensors are available, including one designed for solid or tight mesh conveyors and one for open mesh conveyors. Our state-of-the-art profiling system also provides an easy way to validate your kill step for food safety and FSMA compliance.

Air Flow/Velocity

In combination with other parameters, air velocity influences the texture, coloration, firmness, and baking time of your final product. It can be measured and recorded with the SCORPION® 2 Air Velocity Sensor, which provides you with a precise picture of airflow patterns in the oven. The sensors collect data, at product level, as the array travels through the oven. The number of sensors varies with the width of the conveyor.


Humidity is the amount of water vapor held in the air. While baking, your products make use of the available moisture inside the oven. Without this humidity, the texture and quality of your products will not be as expected. For example, high oven humidity can lighten the color of a product and prevent it from burning, while less humidity will usually result in crustier bread.

Bakeries around the globe depend upon the SCORPION® 2 Humidity Sensor to measure the absolute moisture content of their oven environments through both heating and cooling processes. While traveling through the oven with the product, the sensor yields a precise profile of the moisture it experiences.

Heat Flux

Heat flux profiles are often used when a bakery is trying to produce the same product on two different lines or transferring product from one line to another. When the heat flux component profiles are matched, the two lines will produce the same product.

The SCORPION® 2 Heat Flux Sensor measures convective and radiant heat fluxes at product level and displays results in Btu/hr·ft2 or W/m2. Convective and radiant heat is absorbed by the band, which serves as the conduction mechanism to the product. While traveling through the oven with the product (in a fully loaded oven), the sensor produces a precise profile of heat flux components the product experienced.
