Online Moisture Measurement with Microwaves

New hygienic FlowCell with EHEDG certification

The online measurement of moisture content plays a key role in quality assurance and automation of processes in many industries. With the development of a new FlowCell especially for use in hygienic applications, Berthold is now expanding its portfolio of microwave sensors with another innovative product.

For a representative measurement, the microwaves in the transmission method used by Berthold penetrate the entire material cross-section, which is reflected in a high measuring accuracy. Microwave measurement takes place during the ongoing process and provides real-time information to identify trends in the concentration or dry matter of various liquids, suspensions or pastes.

The new FlowCell is integrated into an existing pipeline and consists of a stainless steel inline housing and two microwave antennas which are connected via clamp connections and are interchangeable at any time. Sealing is accomplished by means of O-rings made of EPDM and two PEEK windows.

Due to the certification of the EHEDG, the FlowCell is particularly suitable for use in the food and beverage industry with its hygienic design and FDA-approved materials. The new FlowCell is available with common process connections and comes in six nominal sizes, from DN 50 to DN 150. In some cases, temperature or conductivity compensation is required. The new design of the FlowCell allows simple integration of appropriate sensors in the immediate vicinity of the measuring point. There, a sampling valve can also be integrated via a second inline housing.

Berthold Technologies is an international leader in industrial process instrumentation. By focussing on technology, powerful and customer-oriented measuring systems and devices are developed and produced. The production of high-quality measuring systems for industry and research began more than 60 years ago in Bad Wildbad in the Black Forest.
