Product Overview

Better Measurements, More Measurements

TheiaVu® TV-250HR (high-resolution) assists quality control professionals to save a significant amount of time while obtaining more precise and repeatable measurement data to improve their production processes. Because some quality parameters are difficult or impossible to quantify using manual methods they are not considered as part of the criteria during quality checks. TheiaVu® allows you to perform these measurements at a fraction of the speed and with a great deal of precision compared to manual methods. The TV-250HR is best suited for inspection of smaller objects (approx 5 mm to 50 mm), bread crumb structure analysis, and applications that do not require washdown.


  • Powerful: Quantify product features difficult to measure manually
  • Automatically collects critical product data
  • Easy to use operator interface
  • Fast: up to 10 objects/second*
  • Versatile: Can be used in lab or production area.
  • Flexible: built-in library with 100+ measurements and growing
  • Measure products up to 91 cm (36” long)
  • Weigh scales and temperature probes as optional accessories

*Actual speed will depend on the size of object and number of different measurements per object.


  • Perform quality checks faster and with better repeatability
  • Know more about your product compared to manual methods
  • Ensure consistent product quality from batch to batch
  • Cost savings through reduced labor and waste
  • Brand protection
  • Save time with reporting, all results are saved & organized
  • Achieve competitive advantages

Used in the lab or at-line, TheiaVu® systems produce critical measurement data on final products or at various stages throughout production for both quality and process control.

Measure Quality Where It Matters

Typical Applications Include:
  • Crumb analysis
  • Incoming inspection: Inspect raw materials quality, such as dough, fruits, and potatoes
  • Batch sampling: Inspect samples of smaller bulk products such as pet food kibble and compound feed pellets
  • R&D: For bakeries or ingredient producers, quantify the baked goods fresh out of the oven based on a new formulation or a new ingredient
  • Process improvement: Inspect product quality at certain steps of the production process for process control
  • Quality control: Before packaging, inspect final products or work-in-progress for quality control
  • Program development: Assistance with creating standards for quality assurance programs
  • Training: Use the TheiaVu® for training staff on in-line or over-line systems, it operates on the same user interface
Finished Product Examples:
  • Bread Products (loaves, baguettes, buns, bagels, english muffins, croissants, muffins, etc)
  • Cookies, crackers, biscuits
  • Snack Foods (snack bars, pretzels, potato chips, French fries, desserts, chocolates, candies, etc)
  • Cheese Products (blocks, snack pieces, wax covered, etc)

How It Works

Compact Machine Vision for Quality Control

TheiaVu® vision inspection systems, also referred to as machine vision systems, use a selection of high-speed cameras, a laser, and imaging software to detect and measure objects as they move along the built-in conveyor belt.

Our proprietary measura® software suite and measurement algorithms can determine the size, shape, color, or composite measurement of any object and convert this information into standard units for quality control purposes. Results are displayed in real-time and data for every object is saved for future analysis and reporting.

To Inspect a Product:

  1. Power on the system
  2. Select the desired measurement profile using built-in operator interface
  3. Place the object on the moving conveyor belt
  4. Instantly view the results on-screen

You can continuously feed multiples of the same product onto the belt without resetting the system and all data will be saved. There is no need for manual note taking or spreadsheets.

Product profiles are easy to adjust or create using the measura® Toolbox module (included). All you need to do is enter your specifications and save. Next time you load the profile, your changes are applied.

System Components

TheiaVu® TV-250HR is equipped with a 9” wide conveyor, full-colour 2D & 3D cameras for high-resolution applications, and special LED lighting for high resolution and porosity applications.


TheiaVu® TV-250HR models are deployed with efficient white LED for accurate color measurement. Additional lighting is deployed for crumb analysis applications.

Camera Options

The TheiaVu® TV-250HR offers camera options for different applications:

  • 1, 2D full color camera with resolutions of approx. 0.2 mm/pix (resolution varies by conveyor width)
  • 1, 3D monochromatic profile camera (works with a laser source for 3D profile)
  • 1, 2D high-resolution color camera for crumb structure analysis and other applications
Other Components
  • Stainless steel conveyor ensures fast sampling and low maintenance
  • Integrated and adjustable system touchscreen allows for easy operator interaction
  • Accessible USB and network connectors allow for easy connection of peripheral devices
  • Plugs directly into any standard electrical outlet (120/220VAC)

Using vision technology, your products are characterized in meaningful ways, including complex details that are difficult and time-consuming with traditional manual methods. Our standard measurements library consists of over 100 basic and advanced algorithms and growing.


Heights Peak, Mean, Center, Edge
Diameters Min, Max, Mean
Slopes Mean End-to-End, Side-to-Side
Shape Length, Width, Roundness
Color Average, Topping, Top Surface w/o Topping
Surface Features Number of Splits, Split Width, Topping Coverage
Others Surface Area, Volume
External Devices Weights, Temperatures

TheiaVu® TV-250HR systems are capable of providing an additional level of detail for analysis – crumb analysis. Crumb analysis provides details about pore size and distribution and texture expectation (airy, dense). This data is important for QA and R&D Teams that are conducting in-depth analysis of their baked products and testing or verifying recipes, as well as for QA Teams to collect accurate, repeatable data for process control. 

The crumb analysis is an option for TV-250HR. It uses a high resolution camera and special lighting for best picture quality. Parameters measured are the number of pores, pore area, largest pore area, largest pore diameter, and average pore diameter. Pores can also be divided into three groups by size with same set of parameters provided for each group.

The custom-designed measura® software drives all of the Sightline vision systems and data obtained by measura® Inspection can be imported into third-party software, giving you the ultimate flexibility when it comes to decision making and process control.

Powerful And Easy to Use measura® Software Suite

The easy-to-use measura® software suite includes a built-in library of over 100 different types of measurements and configurable camera and lighting components for different product needs. The software simplifies the inspection process from product set-up and real-time inspection to process monitoring and quality analytics.
