"We imbibe Pressure Sensor Engineering"
"State of Art Technology for Pressure Transmitters/Pressure Sensors/Pressure Transducers and Pressure Switches"
In the manufacture of our pressure transmitters and pressure switches, we adopt three different technologies, tuned to respective applications and purposes.
The Stainless Steel Technology
The Silicon Technology
The Hydrogen Technology
The products have proven their value in millions of most diverse applications.
THE STAINLESS STEEL TECHNOLOGY
Our stainless steel pressure measuring transmitters have a membrane with applied thin film poly-Si resistors. The deformation-dependent resistors change with pressure generating a voltage that can be converted into any signal.
Benefits:
Very compact and homogeneous design
High long-term stability and dynamic load capacity
Measuring ranges from -1…0 bar to 0…4.000 bar
High precision classes of 0.25 % are possible
Very good media compatibility
Material:
Membrane 17-4-PH / SUS 630
Fitting SUS 304
THE SILICON TECHNOLOGY
In silicon pressure transmitters, the pressure-sensitive element is a silicon membrane into which strain sensitive resistors have been diffused. This technology permits to manufacture sensors in high volumes.
Benefits:
Reasonable large-batch production
Measuring ranges from 0 to 40 bar
Compact design
Highly flexible options by its modular design
Material:
Silicon
Measuring principle piezo-resistive, capacitive
THE HYDROGEN TECHNOLOGY
Our partner PRIGNITZ Mikrosystemtechnik has developed a portfolio of hydrogen-ready pressure transmitters and sensors built around a piezoresistive pressure cell engineered specifically for hydrogen applications. The seam-free construction eliminates welded joints—removing potential leak paths and common weak points—for outstanding long-term durability. In the hydrogen market, these sensors stand out for their ruggedness, powered by PRIGNITZ’s patented P2P technology.
Advantages of our Products for H2:
Monolithic, weld-free stainless steel, no oil-filled cavities
Measuring cell (1.4404/316L)
Vacuum-tight, elastomer-free
Long-term stability with high accuracy
No material fatigue due to embrittlement and permeation
Suitable for harsh environmental conditions and critical media
