Kistler is offering a range of high-sensitivity pressure sensors that are suited for use in the production of fibre-reinforced lightweight plastic structures and composite parts.

This includes those for the automobile and aerospace industries using conventional and high-pressure resin transfer moulding (RTM).

The sensors are also suitable for injection moulding and pressing of temperature-resistant components for domestic appliances and electrical products from thermosetting materials such as bulk moulded compound (BMC), sheet moulded composite (SMC), elastomers and liquid silicone resin (LSR).

Two types are available, both with a front diameter of 6mm; one with a sensitivity of 16.9pC/bar over the range from 0 to 200 bar and the other with a sensitivity of 4pC/bar over the range 0 to 1,000 bar.

Both are suitable for use at melt temperatures up to 450C and are available with a coated front for use with materials containing abrasive fillers or reinforcing materials.

Used with the Kistler Como injection system, the sensors’ ability to detect minute changes in cavity pressure allow the processing of curable, cross-linking compounds to be precisely monitored and controlled.

The resulting mould cavity pressure curve can then be analysed for quality assurance monitoring.

The new high-sensitivity diaphragm pressure sensors are part of the ‘Quality moulding powered by Kistler’ programme that uses mould-cavity pressure to monitor and control the moulding process to ensure minimum rejects and maximum productivity.

Kistler Instruments

Established in Winterthur (Switzerland) in 1957, the Kistler Group now has a worldwide presence with 23 group companies and 30 distributors ensuring prompt, local application support and short delivery times. With a staff of more than 1,000, the Kistler Group is one of the world’s leading providers of dynamic measuring instrumentation.

Kistler’s core competence is the development, production and use of sensors for measuring pressure, force and acceleration.  Kistler’s know-how and electronic systems can be used to prepare measuring signals for use in analyzing physical processes, controlling and optimizing industrial processes, improving product quality in manufacturing and improving performance in sports and rehabilitation.

Kistler offers a comprehensive range of sensors and systems for engine development, automotive engineering, plastics and metal processing, installation technology and biomechanics.

Heavy investment in research and development, 15% of staff worldwide are engaged in research and development, has generated a number of innovations using piezoelectric, piezoresistive and capacitive techniques to provide solutions to numerous force, pressure and acceleration measuring problems. These innovations include the world’s first commercial quartz sensor, two-wire constant current technology to integrate sensors with microelectronic circuitry, high-temperature pressure sensors for use up to 400 Deg C and three-component force measuring sensors.
