Pressure Transducer Typical applications • • • • • • Process technology Plant engineering Food industry Oil- and grease-free applications Ultra-pure gas measurement Machine engineering Description The new series DMU 02 pressure transducers are based on a polysilicon thin film measuring cell, a new technology in industrial pressure measurement. The semiconductor bridge circuit is attached to an isolated stainless steel diaphragm. This measuring technology utilises the positive characteristics of conventional pressure sensors such as a high Pressure Transducer Extremely robust, without seal output signal, excellent dynamic characteristic, high long-term stability. In addition, it is resistant to vibrations and offers a high burst strength. Seals are not required since the measuring cell is directly welded to the process connection. In the case of an open process connection, no hydraulic transfer medium is required making the DMU 02 the

perfect solution for oil- and grease-free applications, pharmaceutical air, gas and ultra-pure gas measurements. If flush pressure connections are required, a second diaphragm is mounted in front of the measuring cell. The Vario diaphragm systems of DMU 02 Vario are filled with special transfer liquids and are hermetically sealed with a weld. There is no possibility of diffusion either of the transfer liquid out of the system nor of the measured medium into the system.
