for you




Development Time



Measurably better - No matter whether high-speed online weight control, moisture measurement, sorting, dryer control, coating or dosing, our high-performance solutions are simple: we provide patented microwave technique tied to passion driven services. Why? The answer is as simple as our solutions: to improve the production process of our clients. Or, in other words: to help our clients to achieve better results.

Our solutions have been developed and designed together with leading companies in several industries for high flexibility worldwide. Our engineers are not just able to adapt our technology to your processes, machines and applications, but also to turn new ideas into new solutions. That’s what we call: Co-Improving®.

The TEWS method enables companies to gain high accurate data about the level of moisture content and density of their products. It’s a one-stop-shop without any sample preparation to optimize the whole production process in terms of cost savings and quality control.


Water Matters.

Product quality and efficiency can be significantly optimized by controlling the moisture content in almost all process steps. Managing the moisture of products is a key factor to achieve better results. TEWS patented solutions deliver high precision results. It's what matters when it comes to company goals and how to achieve them faster.


  • Securing High-Speed-Production – Modern high-speed machines are fragile in a sense that minor deviations from the specified inflow or any piling-up within the production flow leads to severe interruptions. With up to 40,000 measurements per second we are well ahead of all production processes.
  • Plant Efficiency – With our measurement results, machine builders can utilize their advanced machines at an optimum and reduce downtimes and waste to a minimum.
  • Product Quality and Product Safety – A precise moisture level is decisive for the quality. In the industry a wrong moisture level can even harm the product safety as active ingredients may change and turn into toxic or higher the level of explosions if product becomes to dry and dusty.
  • Storage Efficiency – Precise compliance with the recommended water content of components secures product integrity.

It Takes Two.

TEWS patented two-parameter measurement solutions enable companies to work with high precise data in both ways at the same time. Data that relate to the moisture content of products as well as their density. With more than one microwave even multiple content variations can be measured. This leads to even better results in terms of product quality and -efficiency.


  • Mass Flow and Balance Check – Accurate density information being used to assure constant filling levels, content control.
  • Quality Control and Product Safety – perfect final products due to full 100% online production control.
  • Plant Efficiency – Self-adjusting machines based on sensor-controlled and algorithm-optimized production.
Best practice

How Leading Companies Benefit From TEWS.

High Speed Measurement of Yarn

With our ultra-high sensitive sensors we are able to measure the thickness variations in yarn down to 1 Tex (1 gram per 1000m length).

Weight Control on Cigarette Maker Machines

Since its introduction in 1998 microwave technology has replaced Beta-Ray density measurement systems nearly completely. Safe, user friendly, no radioactive sources, additional moisture information, long term stable.

Product Content in Capsules With Varying Capsule Weight

Example of measurement with an additional balance or a second microwave. Measurement of the content inside a capsule despite the fact that the moisture and weight of the empty capsule can vary by up to 10% total mass and the content is only a fraction of the total mass. Possible by measurement of each capsule before and after filling and displaying the correct content.

Where to use

Areas of Application.

In all industries that currently do not use traditional methods to measure moisture, density, weight and other substances that correlate with these parameters.

Microwave is independent or compensated to environmental changes like temperature, humidity, vibrations, light etc. It has no aging or moving parts. It has long term stability. It has shown it can replace balances, density meters, beta ray heads, flow meters, thickness measurement systems and other indirect methods which are less accurate like 1-Parameter systems or light-based systems.
