Process monitoring and industrial inspection solutions

Lenz Instruments S.L. is a technology-based company focused on the development and commercialization of instruments and systems for industrial inspection applications, as well as on providing engineering services in fields related to automation, electronic design, and process monitoring.

Key fields of expertise include non-destructive or contactless inspection technologies based on electromagnetic sensors, vision systems, ultrasound and optical spectroscopy.


In-line Weight, %Fat and %Salt determination for primal cut classification and dry-curing process optimization.


Engineering services in automation, electronic design, and process monitoring


We are present in different sectors, including the food industry, recycling, and photovoltaics.


As a technology based company, we are very active in R&D projects

Our network

We have collaboration agreements with several industrial and academic partners, which help us to create new business opportunities, to improve and optimize our products, and to generate knowledge. Such collaborations provide us complimentary material and human resources to further develop existing and novel products.




A new consortium formed by eight companies, in collaboration with four research centres, aims at incorporating photovoltaic properties into buildings’ facades by integrating high-transparency and optical-quality devices into their tiled surface.


A Pilot Line for Sorting and Recycling Construction and Demolition Waste

We are working on the development of a pilot line for sorting mixed ceramic fractions from construction and demolition waste. The pilot line is designed to process up to 1 ton per hour of input material, and is aimed to sort it into three main streams: grey fraction (concrete), red fraction (brick fragments) and other materials, including gypsum.


First Advanced Optical Inspection System for Next-generation Thin Film Photovoltaics

We have completed the production of an automated inspection system to automatically analyse thin film photovoltaic modules. The system integrates an optical head, which delivers light onto the module, gathers its optical response, and guides the light into different spectroscopic modules for analysis. By means of advanced data processing techniques, this spectral information can be used to assess the quality and efficiency of thin film materials, during the manufacturing process. The early detection of manufacturing defects is of paramount importance to (1) identify manufacturing errors and implement early actions; (2) maximise production yield; (3) ensure the quality and reliability of the modules; and (4) minimise manufacturing waste.


SUNRISE – A sorting and recycling solution for Polyvinil Butyral (PVB) films from laminated glass A sorting and recycling solution for Polyvinil Butyral (PVB) films from laminated glass

On June 1st 2021, it was officially kicked-off the European Project SUNRISE, which aims to develop new solutions for the separation and recycling of PVB films from laminated glass. This project has received funding from the European Union’s Horizon 2020 Research and innovation programme under grant agreement nº958243.
