New high sensitivity pressure sensors for composite materials

New from Kistler is a range of high sensitivity, pressure sensors for use in the production of fibre-reinforced lightweight plastic structures and composite parts 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 6 mm; one with a sensitivity of 16.9 pC/bar over the range from 0 to 200 bar and the other with a sensitivity of 4 pC./bar over the range 0 to 1,000 bar. Both are suitable for use at melt temperatures up to 450°C 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 new 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.
