Herding GmbH Filtertechnik

Herding GmbH Filtertechnik is a manufacturer of filter media, dust collecting systems and filter units for industrial use. Dry dust collecting, aerosol separation and material recovery are the focal points of their work. As part of a demonstration project, Herding GmbH supplied a manufacturer of concrete goods with a removal and treatment system that was used in their dry grinding process. (s. CPG Project: Use of a dry grinding system in the concrete products industry)

Vereta GmbH

For more than 10 years, the company has been opening up new areas of application for thermocouples that are otherwise more likely to be found in high-temperature areas. The methods developed for optimising thermocouple signals enable their use as industrial sensors for level, leakage and flow monitoring. The latest family of climate sensors uses the properties of thermocouples to measure air flows, humidity and solar radiation. A special innovative leap was achieved with the invention of the first sensor for measuring the "felt temperature" or (according to the US patent) "effective temperature". This sensor technology for the demand-oriented and energy-efficient control of temperature- and climate-dependent processes achieved a TOP 5 rating at the international technology award, the Hermes Award 2004. The development department of Vereta has many years of experience in this special field of thermal sensor technology and can avail of the corresponding technical equipment. This includes, among other things, a climatic chamber with integrated flow control, a state-of-the-art bonding system for configuring the sensors on electronic components. Special attention has also been paid to the development of industrial sensors for use in harsh environments. For example, Vereta mass flow sensors are used in flue gas up to 700 °C or the humidity is determined in a process room up to 350 °C. The fine dust measuring case is also a consistent development in this area, which convinces with its robustness and suitability for everyday use.
